Implement APEX stub of API surface so any stub can be replaced with API
surface when APEX stub interface is required.
Unlike other stub interface, APEX stub can be decided if it should be
used after APEX postdeps mutator analyzes which modules should be
included in which APEX. To cover this, APEX stub is being added to the
dependency if the dependency should not be covered with LLNDK or NDK
stub, and APEX stub exists. From depsToPaths, if dependency to both
original module and API library exists, then it choose one of the
dependency and ignore the other.
To cover this logic, a new property is added to the api_surface :
apex_libs. This is introduced as it is difficult to
gather all api library with apex stub before DepsMutator.

Rename export_headers of cc_api_variant as export_include_dirs, because
the property only supports header directory.

Update cc build logic to support NDK variant of cc_api_variant. Any
cc_api_library with NDK variant of cc_api_variant would be treated as
similar with NDK library.

Define CcApiLibrary Variants for LLNDK. Each variant will be defined as
below.
cc_api_variant {
name: "libc",
variant: "llndk",
arch: {
x86_64: {
src: "libs/x86_64/libc.so",
},
...
},
}
And CcApiLibrary will be marked to use this variant as below.
cc_api_library {
name: "libc",
...
variants: [
"llndk",
...
]
}
Soong will replace source of libc cc_api_library as src from
cc_api_variant during build time.

The current combined multi-tree build graph is not accurate. A vendor.c
file currently does not have a dependency on the assembled .h file in
multi-tree out. Previous successful builds of
`multitree_build vendor/vendorimage` were a happy
coincidence (presumably because the actions which copy the .h files from
a speciific inner tree to out/ are at the bottom of the build graph).
Fix this by exporting `cc_api_library.src` to be an order only
dependency of its rdeps (both compile and link). Making an .so file an
order only dependency of _compilation_ is probably confusing, but I
think it will be less confusing than the other alternative I could think
of (creating .timestamp files for each api_surface include dir and
creating phony targets to make them available from top-level to chdir'd
inner tree)

There are some module definitions which are implemented for the proof of
concept, but these modules are not in use now. This change removes
unused module definitions to reduce confusion.

Switch from `PathForModuleSrc` to `PathForSource`. The latter does not
check that the target path exists in the tree. This is necessary since
the prebuilt stub and header directories are not guaranteed to exist
when Soong analysis begins (Step 2a)
Build orchestrator will be responsible for putting these files in the
right place as part of Multi-tree ninja invocation (Step 4)

Introduce cc_api_library, which reflects imported API from other
inner-tree. This cc_api_library module type will later refer from
the other ninja module which generates stub library from the interface
description.
Tested environment :
* original libc definition has been removed temporarily, to ensure that
imported api stub library is being used from build
* Added new definition of libc as below
cc_api_library {
name: "libc",
arch: {
x86: {
src: "libs/x86/libc.so",
},
x86_64: {
src: "libs/x86_64/libc.so",
},
},
header_libs: [
"libc_headers",
],
export_header_lib_headers: ["libc_headers"],
min_sdk_version: "9",
vendor_available: true,

This change contains a prototype implementation for multitree. Several
interfaces and modules are added.
1. Imported/Exported
Modules implementing Exportable interface can export artifacts to other
components. "imported_filegroup" modules can import generated artifacts from other exported modules.
2. Multitree metadata
It contains information about imported/exported modules in each
component, and can be generated via "m update-meta".
3. cc library stub
It's based on prototype stub libraries. It uses imported/exported
mechanism to expose a C API, with a map.txt file and header files.
