The data attributes for cc library rules is dropped by their starlark
macros, so serves no real purpose. Furthermore, this unused dependency
proves problematic for allowlist v2, as there are many cases at HEAD
where the corner-case "requires" dependency would otherwise mark a module
as unconvertible.

This module type is used by a single soong module - `common_libc` in
bionic/libc
Implementation details
- Convert this module type to ndk_headers rule. Bazel's ndk_headers rule
will have a boolean attribute `run_versioner` to determine if
verioner should be run on the headers
- Add this module type to the alwaysConvert bp2build list
- Add the converted target for `common_libc` to the deps of
`ndk_sysroot`. This ensures that unbundled apps link against the
versioned NDK headers of libc

bp2build tests should not use bp2build_available:false test deps,
because, with the "allowlist v2" feature, this will cause these modules
to stop being converted with bp2build. Instead, such test deps should be
"stubbed", which effectively treats them like targets in pre-existing
BUILD files on the filesystem.

This target will have a dependency edge to every bp2build equivalent of
Soong's ndk_headers. In b builds, sdk variants will compile against this
aggregated CcInfo providing target
A non monolithic alternative was discarded after conversations in
b/300504837#comment1-5
Contents of bp2build generated target: https://paste.googleplex.com/6643820291686400
Implementation details
- Since there is no equivalent Soong module for ndk_sysroot, hardcode
bp2build/build_conversion.go to collect all ndk_headers soong modules.
Add them to `deps` of a ndk_sysroot target
- Create `ndk_sysroot` in build/bazel/rules/cc/BUILD.bazel. This is
expected to be a temporary location. This will use the
cc_library_headers macro
- Update SetStubsForDynamicDeps so that sdk variant of rdeps depends on
//build/bazel/rules/cc:ndk_sysroot. This will provide a CcInfo during
compilation. Since ndk_sysroot is of type cc_library_headers, it will
not get packaged into the apk.
- Refactor `goBazelTarget` to a generic `bTarget` so that it is
representative of the expanded usage by ndk_sysroot

Allowlist v2 will change bp2build by automatically disabling rdeps of
unconvertible modules. Many bp2build tests create bp2build stub modules
without an implementation,
This CL changes setup of such tests to also contain a BUILD file with
"stub implementations" of equivalent targets, to keep these test targets
convertible.
To verify this change in-place, this CL removes `bp2build_available:
false` from these dependencies.
This is a test-only change for bp2build tests.

A single proto providing directory can be used by multiple soong modules. Some of these
can be
1. Host specific
2. Device specific
3. Both host and device
Since the generated proto_library can have 1:many mapping, it should
have an empty target_compatible_with. Compatiblity will be enforced at
the top-level {cc|java|python}_proto_library.
(This is a followup to aosp/2727054 which did not handle this correctly)
Test: Added a unit test
Change-Id: I09b3def70e3d043fd8ba0d1eb4ffff1910f097d1
The fixes are
- Dedupe the dir list. Since we partition the proto srcs per pacakge and
then iterate the map, a single include directory was being listed
multiple times
- Drop target_compatible_with from these proto_library targets. The
compatibility will be enforced at the top-level <lang>_proto_library.

This is a fix similar to aosp/2707793. This adds manual tags to the
top-level proto_library created in the root package, plus any
dynamically created proto_library targets for proto.include_dirs. These
proto_library targets might not specify their deps correctly and might
be unbuildable.
(We need to keep these targets because they provide a ProtoInfo for
cc/java/py source gen)

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.

Note that this CL does not do the `CheckBadHostLdLibs` validation of
Soong. There are some different ways to do this, and these are being

Create a select statement for every api_domain a library could be

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

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.
