Soong's proto.include_dirs becomes the -I path for aprotoc cpp code
generation. This does not translate well to Bazel because it runs this
action in a sandbox. Even if we construct an -I path, the .proto files
will not be there. This CL attempts to handle this kind of dependency
automatically via bp2build.
For this hypothetical example
```
foo.proto # contains `import bar.proto"
Android.bp # cc_library {srcs:"foo.proto", p.include_dirs:["subdir"]},
subdir/bar.proto
```
Implementation details for CcProtoGen of foo
- Glob the labels of .proto files for each includeDir, and create a
proto_library that encapsulates them.
- Since Bazel poses a contraint that proto_library target needs to be
in the same pacakge as the .proto file, the proto_library might be created
in a subdirectory with an import_prefix
- Add bar's proto_library as transitive deps of foo's cc_proto_library.
This will be added to -I during aprotoc. We cannot add them to `deps`,
otherwise bar's symbols will be statically linked into foo's .a
file.
Implementation details for clang compile of foo
At the end of CcProtoGen, we have converted foo.proto
to .cpp/.h files. To compile them to .a files, we need the .h files
generated from bar.proto. Soong specifies this at the
top-level cc_library soong module, so add those deps as the
implementation deps for clang compile.
(Will add support for java in a follow-up CL)

This is a fix for aosp/2693190 that handled .proto files that end up in
different bazel packages. It did it by creating proto_library targets in
the correct bazel package.
Changing the granularity causes issues if the the new proto_library in
the subpackage imports a .proto file from a parent package or a
different package. e.g.
```
tmp
├── foo.proto
└── subdir/import_foo.proto # contains an `import "foo.proto"`
└── subdir/Android.bp # package boundary
├── Android.bp # contains a cc_library with foo.proto and
# subdir/import_foo.proto
```
At ToT, the ProtoInfo we provide to CcProtoGen is correct, but the
proto_library in subdir/BUILD will not compile because it does not have
a dep on the proto_library in ./BUILD
This CL creates a workaround by adding `manual` to the proto_library
targets. This CL is based on the assumption that the buildable unit in
bp2build is cc_library_*, and not proto_library necessarily (atleast
till we do a manual/automated cleanup)

Bazel poses a strict requirement that .proto files and proto_library
must be in the same package. This CL handles this automatically by
creating the proto_library in a separate dir/package if necessary
Implementation details
- Partition the `srcs` by package. `srcs` has been computed using
`transformSubpackagePath`, so the information about packages is
available at this point
- Create a proto_library in each package by using
`CommonAttributes.Dir`. Collect all these additional libraries
and put them in `info.Proto_libraries` so that they get added as deps
of (cc|python|...)_proto_library
- Add an import_prefix to the proto_library in subpackages relative to
the current directory. This relies on the assumption that every src is
beneath the current directory (Soong will complain if a path in
Android.bp contains ../)
filegroup module type uses a separate code-path to create proto_library.
This will be handled in the next CL in stack.

Change-Id: I437fc89092321b26c5f0511387cde9e84084d6f9
The current API restricts creation of targets to the directory of the
visited soong module. This CL proposes adding a `Dir` property in
`CommonAttributes` that can be used to create a bazel target in
a specific dir. The use case for this is to dynamically create
additional targets for proto_library that are adjacent to .proto files
(Bazel poses a strict requirement about proto_library being in the
same package as the .proto file, but Soong does not)
Usage is restricted to dirs that have an existing Android.bp file. There
are some places in bp2build where we use existence of Android.bp/BUILD
on filesystem to curate a compatible fully qualified path (e.g. headers).
If we use `CommonAttributes.Dir` to arbritraily create BUILD
files, then it might render those curated labels incompatible.

If `srcs` contains a gensrcs/genrule module, the current bp2build module
will put it in the catch-all `srcs` attribute. This is reserved for .cpp
sources, so if the genrule produces a .proto/.aidl/... file, this will
fail.
This handles genrules that produce .proto files. To implement this, this
creates an additional partition that detects if the other module is a
genrule/gensrc that produces .proto files. If true, it will append it to
the proto partition.
This CL does not handle
- genrule that produce .c/.aidl/.yacc/.... files. They will continue to
be partitioned into the catch-all partition

The "bazel sandwich" is a mechanism for bazel to depend on make/soong
outputs. The name comes from the fact that bazel is now at the top
and bottom of the build graph. This is intended to allow us to work
on converting the partition builds to bazel while not all of the
dependencies of the partition have been converted.
It works by adding the bazel_sandwich_import_file rule, which emits a
dangling symlink that starts with bazel_sandwich:, and includes
information that the aquery handler in soong reads. The aquery handler
rewrites the symlink so that it points to a file generated by
make/soong, and adds a ninja dependency from the symlink to the file
it's targeting.
This allows us to depend on make-built files from bazel, but notably
it doesn't allow us to depend on analysis-time information from make.
This shouldn't be a problem for the partitions, but limits the use of
the bazel sandwich to similar, less complicated types of builds.

These tests cannot be run with b since it uses functions that should not be
used outside tests, and it enforces this by looking at os.Args. Since
the pattern (`-test`) is missing in os.Args, these tests panic in b.
A module can be a dep of soong_build via two mechanisms
1. Listed in deps explicitly
2. Via plugin_for to create a reverse dep
This CL denylists (1) explicitly. e.g. soong-android. Another option
would have been to denylist by using Deps() of soong-build, but that
would denylist `golang-protobuf-proto` as well
This CL denylists (2) programmatically.
Note that this CL only denylists creation of the `go_test` target. We
will still create `go_binary` and `go_library` for soong since there
might be tools that depend on soong.
e.g.
```
--> depends on
dexpreot_gen --> soong-dexpreopt --> soong-android (test failure)
```
(The above example means that we might need to convert _some_ of soong
after all, but we can refactor the common bits to common utils. Keeping
this out of scope for now).

For go modules with non-empty testSrcs, we will create an additional
go_test target. To build a standalone test executable, we need to
include the source files in the compilation unit. This will be done
using the `embed` attribute
1. For tests of go_library, this is straightforward. It will embed the
go_library and "inherit" its .go files and deps
2. For tetss of go_binary, we need to create an additional go_source
target since go_binary cannot be embedded inside a go_test
Using `b test` for these tests revealed that certain tests are not
hermitic and rely on `testdata` files checked into the tree. This CL
introduces an allowlist to skip generating go_test targets for them.

There is one major deviation between Soong and Bazel's
go_binary/go_library. Soong
collects the deps in the transitve closure and puts them on compile/link

This module type does not implement android.Module, and therefore we

Instead this has been special-cased inside bp2build/build_conversion.go.
Because of the above, we also do not have access to useful functions
available in the ctx object of ConvertWithBp2build. This includes
1. Finding the package (directory) of a dep. This requires getting a
handle of the underlying module from its name (string). To solve, we
do a pre-visit to collect this information. This did not increase the
wall time. On my machine, `m bp2build --skip-soong-tests` takes ~14s
before and after this CL
2. Converting srcs to labels. This requires glob and package boundary
resolution. This CL introduces a partial implementation for this
function. (glob patterns are not used in go tools)
For (1), I considered creating a `ModuleFromName` on
`blueprint.Context` instead of a pre-run, but this increased the time to ~27s.

Introduce aidl.libs prop on cc libraries to pass in aidl_library. The goal is to eventually disallow aidl.include_dirs (a pattern for passing aidl headers dir for aidl compilation) and enforce aidl headers to be explicitly specified in Android.bp.

For converting the art plugins to pure soong, it would be useful to
have a property that's qualified on both a soong config variable and
the OS. Soong had very little-known support for this by saying your
soong config variable changes the "target.android.cflags" property,
and we didn't supporting bp2building that. Add the bp2build support.
This cl also refactors product variable and soong variable bp2building
so that they're separate from each other, which I think makes the code
easier to understand.

Create a select statement for every api_domain a library could be
included in. The stub/impl
selection heuristics per apex domain are
1. If dep has stubs and the api domain appears in dep's apex_available, use
impl
2. If dep has stubs and the api domain does not appear in dep's
apex_available, use stubs
(Category 3: If dep does not have stubs and the apex does not appear in
dep's apex_available, then a separate apex_available validation in Bazel
will emit an error).
Platform variants have been special-cased for now to use equality of
apex_available for stub/impl selection

apex_test do not "override" the source apexes that they test. However,
similar to override_apexes, test apexes have the same path
(/apex/<apex_name>) on device. Instead of creating another property,
reuse the existing base_apex_name property. The use case for this will
be for creating selection statements for stub/impl selection.
Test: go test ./bp2build
Change-Id: I4b7548e0e0fc920e407e1c5e5c00e87efc6e70c9
The use case for this is for creating a select statement for stub/impl
selection. Since Bazel propagates apex_name from the top-level apex,
the source apex and test apex builds a specific library in two different
configurations. We need select statements for both these two
configurations, but this metadata might not always exist in Android.bp
since test apexes are not necessary to be listed in Android.bp files.
To overcome this, the select statements will be created per api domain
instead. This CL uses a naming convention to infer the api domain of
apexes.
Test: go test ./bp2build

Although paths to resource files in a Bazel java_library should be
relative to the package, the directory structure in the resulting jar
will have resources under the full path from the top-level of the
workspace, e.g. if a library in "a/BUILD" has java_resouces as
"res/res.txt" then by default the res.txt file would appear under
"a/res/res.txt".
Fix this by adding a resource_strip_prefix in that case.

To avoid verbosity, we currently dedupe keys in axis if its value
matches the value of //conditions:default. For axes where all values
might match the default value, we would effectively drop the common
value.
To fix this, we are now dropping the select statement and not the common
value.

These are created by bp2build in /build/bazel/rules/apex. Eventually
these config_settings should likely be colocated with the source apex
definition.
Another alternative was to make Bazel's apex a macro that generates a
config_setting. I did not pursue this further for now since it requires the
apex_available of every allowlisted cc_library to also be allowlisted.
This might not always be true (e.g. com.android.runtime)
Test: go test ./bp2build

The use case for this is creating config_setting(s) specific to an apex
variant and selecting stub/impl in that config_setting. We likely need
only a handful of such config_setting(s), but determining that list
requires iterating the build graph.

There are a number of instances where we are exporting information
from soong to bazel via soong_injection. This could be more bazel-centric
if the information was instead held in bzl files, and both bazel and
soong read it from there.
Add a starlark package that will run
//build/bazel/constants_exported_to_soong.bzl at initialization time,
and then results can be retreived with GetStarlarkValue.
Since changes to the starlark files mean that soong has to rerun,
add them as ninja deps.
Unfortunately, the starlark code has to be run at runtime rather than
pregenerating their results, because tests run from intellij wouldn't
go through any pregeneration steps. This means that starlark is run
multiple times during the build, once per test package and once per
primary builder invocation. (currently 3, could be reduced to 2 if we
made the symlink forest generation into its own standalone tool) The
starlark code we have so far in this cl is very fast, roughly half a
millisecond, so it's not a big deal for now, but something to keep an
eye on as we add more starlark constants.

Note this doesn't entirely match Soong's logic but is an improvement to
allow linking against implementation when two cc modules are
apex_available to the same module.
It is not possible to recreate the logic for "directly in" without
significant changes to bp2build as we do not add dependencies nor run
apex mutators. Rather than trying to replicate this, we would be better
off refactoring Soong to no longer support the "directly in apex" logic
and require users to correctly specify apex_available.

Since the source_library attribute of _cc_stub_library_shared was a
label attribute, the source library was added as a dependency of the
stub which doesn't always make sense. E.g. it caused validation actions

library.
This change converts the label attriubte to a string attribute so that
we don't add the dependency.

With this CL, we avoid deleting the bp2build directory and regenerating
all BUILD files. Instead, we regenerate BUILD files which have changes
on the filesystem, and delete old BUILD files which should no longer
exist.
This improves incremental Bazel server performance by about ~5 seconds.
Previously, Bazel would have cache misses for regenerated packages, and
would thus need to analyze them even if no meaningful changes took
place.
For ease of implementation, we avoid removing stale (empty) directories
from the bp2build workspace, but this should have no effect on the
build. (These will be removed on next clean)

This fixes two main sources of nondeterminism:
1. Fix a bug in the ConfigurationAxis comparator (which caused
ConfigurationAxis sorting to be nondeterministic)
2. Process C++ dependencies using the sorted ConfigurationAxis order. In
theory, the order in which dependencies are processed shouldn't
matter (as they should end up in different select stanzas). However,
in the case of InApex stubs, this is not the case; we now ensure
that lists are concatenated in a predictable order.
Added bonus: Some cleanup with SortConfigurationAxes which
makes use of go generics (this made it easier to debug this issue).
Will follow-up with regression tests.
