Previously, when referencing a cc_library as a static_lib from a
converted module, the corresponding target would depend on the "root
target" of that cc_library. This resulted in a superfluous dependency on
the shared target of the cc_library dependency. This superfluous
dependency could sometimes result in cycles.
This change ensures the static target name is directly specified in such
cases.

Technically, tzdata apex depends on
//system/sepolicy/apex:com.android.tzdata-file_contexts. Builds suceeded
regardless due to bp2build generating a filegroup for all files in a
directory.
This also requires an update to the check in apex/builder.go to address
the fact that outputs (including filegroups) from Bazel in mixed builds
will be in a Bazel out subdirectory. This change also corrects a
potential bug that would not support all subdirectories under
system/sepolicy as golang's path.Match does not treat ** as recursive.

This builds cap_names.list.h, which uses an eponymous filegroup
"generate_cap_names_list.awk" in Soong, but uses the file target
directly in Bazel.
This also improve filegroup support for mixed builds, by issuing a
cquery call _without_ arch. Filegroups in Soong don't have configurable
properties, so don't generate Bazel filegroups into buildroot's
config_nodes (which was x86_64 by default).

- If no system_shared_libs is specified, bp2build writes no attribute
value. In this case, the bazel library macros determine the correct
default behavior.
- If any system_shared_libs is specified for any variant, then bp2build
writes the value verbatim. This includes if an empty list is specified,
as this should override defaulting behavior.
Note this defaulting behavior is incomplete and will be incorrect in
corner cases. For example, if, in an Android.bp, system_shared_libs is
specified for os.linux_bionic but not for os.android, then the bazel
default for os.android will be incorrect. However, there are no current
modules in AOSP which fit this case.
As a related fix, supports static struct for cc_library_static.
Also, removes some elements from the bp2build denylist.

Fixes: 193866723
Change-Id: I5fb38c8b2e8edaecef44162491d399c0223d3fb1
This fixes a bug which was a misunderstanding of soong properties:
Soong's cflags pertain only to C and C++ language, whereas bazel's copts
pertain to all three languages. This change ensures that asflags are
added as specifically asflags, and the 'copts' for the static library
macro pertains only to C and C++ languages.
This requires a somewhat hacky workaround for asflags, however: Since
assembly sources also need includepath-related flags, this duplicates
these flags between copts and asflags. To reduce verbosity of
bp2build-generated targets, this also ensures that asflags are omitted
in cases where there are no assembly sources.

This change enables checked-in BUILD files like
prebuilts/clang/host/linux-x86/BUILD.bazel to be merged cleanly with the
bp2build generated one into the synthetic workspace.
The checked-in BUILD file contains a package() declaration that bp2build
also generates. To avoid double declaration, the BUILD file writer now
checks if the BazelTargets contain handcrafted targets. If so, it
delegates the package declaration to the handcrafted BUILD file instead.
This change also sorts the bp2build targets before the handcrafted ones,
and adds a section header to demarcate the two sets of targets.

There are two pieces to make this work:
1. Local include paths must include $(BINDIR)-relative paths, to support
generated headers in those directories.
2. The srcs that bp2build outputs for BUILD targets must include labels
for targets given in generated_hdrs and generated_srcs.
Support for exported_generated_hdrs intentionally deferred.
This allows us to remove several targets from the bp2build denylist.
Some are moved to the mixed build denylist, because genreated headers are
still unsupported in mixed builds.

This now works with --features no_copts_tokenization. With tokenization,
the escaped empty string '\"\"' became an actual empty string '' on the
command line, setting -DWILDABBR to the wrong value.
However, no_copts_tokenization unveiled other problems with Android.bp
flags, such as spaces in existing cflags like
https://cs.android.com/android/platform/superproject/+/master:bionic/libc/Android.bp;l=288;drc=a0a4a6c2967b5b3c02c951ea1145f32ed5564ab9
- this trips up Bazel's copts when generated literally, so the
fix (other than splitting on space and making Soong accept strings that
don't start with dashes as cflags) is to make bp2build split cflags on
spaces before generating them as copts.

This CL adds the ability to filter cc_library modules to only generate

For example, the libstdc++ library is buildable as a static library,

This CL is pretty large, so I recommend starting with reading the newly
added tests for the expected behavior.
This change works in conjunction with the linked CLs in the Gerrit topic.
Those CLs add support for new platform() definitions for OS targets
specified in Soong's arch.go, which are configurable through
Android.bp's `target {}` property. It works similary to previous CLs
adding support for the `arch {}` property.
These configurable props are keyed by the OS: android, linux_bionic,
windows, and so on. They map to `select` statements in label list
attributes, which this CL enables for cc_library_headers' header_libs
and export_header_lib_headers props.
This enables //bionic/libc:libc_headers to be generated correctly, from:
cc_library_headers {
name: "libc_headers",
target: {
android: {
header_libs: ["libc_headers_arch"],
export_header_lib_headers: ["libc_headers_arch"],
},
linux_bionic: {

export_header_lib_headers: ["libc_headers_arch"],
