Previously in order to make use of dist entries with tag properties it
was necessary for each module type to be modified to store the results
of GenerateTaggedDistFiles(module) in the AndroidMkEntry.DistFiles
property. This change generalizes that mechanism to work across all
module types.
This change does improve the behavior of a couple of tests where
previously a dist with tag property was ignored because tagged dist
files were not available now it is used correctly.
Some module types do not implement OutputFileProducer interface and so
they cannot handle dist with tag properties. This change makes it an
error to attempt to do that. That necessitated adding OutputFiles(tag)
method to customModule in queryview_test.go as some of the tests in
that file used dist entries with tag properties.
Follow up changes will remove the code that was made redundant by this.
Test: m nothing
m dist sdk - before and after this change, compare result to
make sure that there are no significant differences.

The sbox tool is used to wrap genrule actions, and run them in a
temporary directory. Afterwards, the outputs are moved into their
proper location in the output tree. However, some tools embed the file
name of the output file (as passed to the tool) into the output file.
For example, the perfetto code generator script uses the output file
name to generate a C header guard when it generates
perfetto_src_base_version_gen_h/gen/perfetto_version.gen.h.
When using remote execution / remote caching, these genrule actions are
run locally whenever the output file doesn't exist, effectively making
them unique (across time and between users).
They then cause cache misses on all actions depending on these output
files as well as on transitive actions. In the above example, this
causes libperfetto.so to differ, which then causes all actions
depending on libperfetto.so to be rerun unnecessarily.
As a fix, this commit changes the sbox tool to use the sha1 hash of the
manifest path. The tool already seems to assume that there are no
concurrent runs of the same tool with the same manifest (otherwise
it would fail flakily depending on exact timing). It seems therefore
safe to use a temporary path deterministically derived from the
manifest path.
Test: ran multiple builds w/ remote execution; observe proper caching

The hardlink optimization attempts to save I/O by hardlinking input
files into the sandbox instead of copying them, but it never works on
a Linux build due to nsjail always making out and the source tree into
separate bind-mounted filesystems. If the optimization did work it
would actually cause build failures when it hardlinked the relative
bionic/libc/fs_config_generator.py symlink into the sandbox directory
without the target. Just remove the optimization for now since it
never works.

$ bazel query 'attr(apex_available, //apex_available:platform, //...)'
$ bazel query //art/dalvikvm:dalvikvm--linux_glibc_x86_64 --output=build | grep compile_multilib

This patchset changes bazel_overlay to generate soong_module as a macro,
instead of a rule, and generate module properties in the BUILD files as
kwargs to the soong_module macro.
Here's a sample of the new BUILD files with module properties:
bionic/libdl/BUILD.bazel:
https://paste.googleplex.com/6484466996346880?raw
art/build/apex/BUILD.bazel:
https://paste.googleplex.com/5461276001042432?raw

soong_module is now a macro that conditionally expands to underlying
soong_<module type> rules with statically defined attributes. In this
CL, we are starting with a hardcoded filegroup rule definition to
demonstrate the conditional rule loading within the soong_module macro.
If the module_type matches an existing Bazel rule, soong_module forwards
the entire **kwargs into the rule, which Bazel typechecks.
Non-filegroup module types will be expanded into generic_soong_module,
but with the kwargs dropped.
This approach allows us to:
1) Programmtically generate soong_<module type> rules for all module
types available in Soong, together with the statically defined attribute
types in `attrs`.
2) Incrementally migrate and test individual module types from
generic_soong_module to their module rule shims.
3) Swap out the module rule shims to the actual Bazel rules (e.g
cc_library, java_library) and perform attribute manipulation in Starlark
itself.
Example of querying against the 'srcs' attribute in soong_filegroup:
```
$ bazel cquery 'kind(soong_filegroup, //...)' | wc -l
590
$ bazel cquery --output=build 'attr(srcs, "linker.cpp",
kind(soong_filegroup, //bionic/...))'

hardcoding them like `soong_filegroup`.

The Bazel overlay is a directory at out/soong/bazel_overlay that
replicates the layout of the AOSP Soong module tree, but as a Bazel
workspace. Each Soong module variant is represented as a BUILD target
created with the `soong_module` rule.
To create this overlay, run `m bazel_overlay`.
A `soong_module` target can depend on other `soong_module` targets.
These dependencies replicate each module's `directDeps` in the Blueprint
graph, just before `PrepareBuildActions`.
This enables users to use bazel query as a way to introspect the Soong
module graph. For example,
- Direct reverse dependencies of //bionic/libc:generated_android_ids in
//bionic/libc/...:
$ bazel query 'rdeps(//bionic/libc/...,
//bionic/libc:generated_android_ids, 1)'
//bionic/libc:libc_bionic_ndk--android_recovery_arm_armv7-a-neon_static
//bionic/libc:libc_bionic_ndk--android_ramdisk_arm_armv7-a-neon_static
//bionic/libc:libc_bionic_ndk--android_arm_armv7-a-neon_static_com.android.runtime
//bionic/libc:libc_bionic_ndk--android_arm_armv7-a-neon_static
//bionic/libc:generated_android_ids
- Why does com.android.runtime depend on lzma?
$ bazel query
'somepath(//bionic/apex:com.android.runtime--android_common_com.android.runtime_image,
//external/lzma/...)'
//bionic/apex:com.android.runtime--android_common_com.android.runtime_image

//external/lzma/C:liblzma--android_arm_armv7-a-neon_shared_com.android.runtime
- What does the dep graph of //bionic/libc:crtbegin_so look like?
$ bazel query

Currently, the build timestamp saved to the build_date_timestamp
field in the MetricsBase metrics protobuf usually comes from a text
file named build_date.txt. It may not be accurate for metrics purposes.
Instead, use the build start time from Soong main UI for a better
timestamp.

From aosp/1329396, the RBE metrics protobuf file is part of the

protobuf file before sending to the uploading process.
