For an AIDL file, five files are generated for the CPP backend: cpp
output, depfile, and three headers. Previously, the cpp output and the
dep file were created at <module_out>/gen/<abs_path_to_input_aidl>.cpp,
while the headers were at <module_out>/gen/aidl/<package_name>/*.h.
This not only looks inconsistent, but more critically makes it difficult
for the aidl compiler to infer the path to the headers that the build
system registered as implicit outputs. Inferring the implicit outputs
by the aidl compiler is needed because otherwise users will see the
error message from sbox just saying that some of the expected files are
not created. This can happen when the input AIDL file is put directly
into the srcs property without specifying the base directory, e.g.
some/subdir/android/foo/IFoo.aidl where the pacakge is actually
android.foo.
In order to make it easy for developers to fix such an error,
I0f23b6027ba3a4755cc2901f4a7f7fc70bffd0ef introduces a check in the aidl
compiler which is triggered earlier than the sbox error. The compiler
now enforces that the cpp output is at
<out_dir>/<package_name>/<type>.app. When the check fails, it suggests
to fix that by correctly feeding the AIDL file via filegroup and the
path property.
This change in Soong is required to satisfy aidl compiler when the base
directory is correctly set. The cpp output is now at
<module_out>/gen/aidl/<pacakge_name>/<type>.cpp.

Previously, a cc library that included .aidl, .proto and/or .sysprop
files and exported headers generated from at least one of those types
would actually export generated headers from all of them.
While headers generated from .sysprop files are always exported those
generated from .aidl or .proto should only be exported when explicitly
requested.
This change treats them separately as expected. It has the potential
to break the build as it could reduce the set of headers exported and
so a dependent module that needed those would break. The fix in that
case is to simply add one (or both) of the following to the module
that previously exported those headers:
aidl: {
export_aidl_headers: true,
}
proto: {
export_proto_headers: true,
}

To support module specific lexer flags, this follows the same strategy
as the yacc flags:
- add LexProperties to the BaseCompilerProperties
- propagate those flags to the generator generation (i.e. genLex)
- add a placeholder for custom flags
- replace the placeholder with the concatenated flags
This might not support escaping very well, but I figured that this is a
very edge case. Support for escaping etc. could be added later on.

This allows setting per-module make variables earlier in the build,
particularly for prebuilt_build_tool users like LEX/M4/BISON. I moved
filegroup over because it's a simpler common interface, but it doesn't
strictly need it.

This fixes an incremental build issue where we didn't clean up old aidl
header files (or necessarily notice that they were updated).
We do this by declaring the header files as outputs in the build graph,
but this means that the src file name needs to be convertible to the
aidl package name, as that's how the header file paths are created. In
many cases, filegroups can be used to strip path prefixes from the aidl
files.

A newly introduced sysprop_library soong module will generate a
java_sdk_library and a cc_library from .sysprop description files.
Both Java modules and C++ modules can link against sysprop_library
module, thus giving consistency for using generated sysprop API.
As Java controls accessibility of Internal / System properties with
@hide and @SystemApi, 2 different header files will be created. And
build system will selectively expose depending on the property owner
and the place where the client libraries go into.

From now on, a c++ shared library can be built only with adding
".sysprop" description file to srcs. Sysprop library generator will
automatically generate a .cpp and .h files, and the header file will be

schema of description file, see system/tools/sysprop/sysprop.proto.

Historically, we've always passed '-I .' as the first argument to
protoc, essentially treating all proto file package names as their full
path in the android source tree. This would make sense in a monorepo
world, but it makes less sense when we're pulling in external projects
with established package names.
So keep the same default (for now), but allow individual builds to opt
into using local paths as the default names with
'canonical_path_from_root: false'. A cleanup effort and/or large scale
change in the future could change the default to false.
As part of this, run protoc once per input proto file, since the flags
may need to change per-file. We'll also need this in order to specify
--dependency_out in the future.

This centralizes verification and common operations, like converting the
path to a source file to the path for a built object.
It also embeds the configuration knowledge into the path, so that we can
remove "${SrcDir}/path" from the ninja file. When SrcDir is '.', that
leads to paths like './path' instead of just 'path' like make is doing,
causing differences in compiled binaries.
