1f6d90f4c7 Create 'cc_prebuilt_test_library_shared' module type
This new module type allows cc_test modules to depend on prebuilt
shared libraries and have them included as data dependencies alongside
the test binary.

Test: Manually verified to facilitate mk-to-bp migration of
bionic-unit-test prebuilt dependencies (aosp/1339035)

380fc3615c Enforce min_sdk_version of apex(use_vendor:true)
Even though use_vendor:true is prohibited, there is media.swcodec apex
which is still use_vendor: true and also needs to support Android10.
(min_sdk_version: 29)

Because LLNDK stubs were provided only for the current VNDK version,
media.swcodec couldn't be built against min_sdk_version: 29.

This change introduces additional versions for LLNDK stubs which are
enforced when an apex with use_vendor: true sets min_sdk_version.

To make things easier, the versions of LLNDK stubs are borrowed from its
implementation libraries.

eabaedd520 Fix product variables in defaults modules
Product variables structs are generated at runtime to contain only
the properties that apply to the current module.  Defaults modules
always contained all product variable properties. Defaults modules
apply their properties to the target module using
proptools.PrependProperties, which prepends structs that have
matching types.  Filtered property structs had a different type
and were dropped.

Even after adding filtering to the defaults product variable
properties, defaults modules may contain more property structs
than the target module they are applied to, so the product
variables struct for the defaults module could contain more
fields than the product variables struct for the target module.
Use proptools.PrependMatchingProperties when applying defaults
of product variables instead, which will apply matching properties
across types.

8471cdaced Implement vendor snapshot
Vendor snapshot can be captured with "m dist vendor-snapshot". With
vendor snapshot and vndk snapshot, older version of /vendor and newer
version of /system will be able to be built together by setting
BOARD_VNDK_VERSION to past vendor's version.

Only vendor modules under AOSP are to be captured. In detail, modules
under following directories are ignored:
- device/
- vendor/
- hardware/, except for interfaces/, libhardware/, libhardware_legacy/,
  and ril/

Test modules (cc_test, etc.) and sanitized modules are also ignored.

e5ba28648f build: Link the unwinder dynamically into platform and vendor binaries.
Instead of linking the unwinder statically into every binary, link it
dynamically, by exporting the symbols from libc.so. This has a number
of advantages:

- Reduces image size (system.img size decreases by 1.7MB on walleye-userdebug,
  and 1.2MB on crosshatch-userdebug).
- Allows us to easily change/upgrade the unwinder throughout the system,
  including vendor prebuilts.
- Allows code outside of libc++ to define custom personality routines.
  Previously, personality routines would call the unwinder routines in the
  local binary, which would cause problems with unwinders with global state
  (such as the libgcc unwinder) if the copy of the unwinder used for unwinding
  (normally libc++'s copy) were different from the copy linked against the
  personality routine.

5f7f7e8a39 Create product variant for product partition
When PRODUCT_PRODUCT_VNDK_VERSION is set to 'current', product
modules are enforced to use only VNDK libs from the system partition
as BOARD_VNDK_VERSION does to vendor partition.

Modules with 'vendor_available: true' create product variant as well
as core and vendor variants. The product variant as an image variant
is used for the modules in /product or /system/product.

It must not affect the current build behavior without
PRODUCT_PRODUCT_VNDK_VERSION set.

075c417837 Improve cc tests by adding fuzzer mutators
This fixes an issue that arises when deduping cc build component
registration code.

The fuzzer and fuzzer_deps post deps mutators were not previously
added when running cc tests. That meant the tests were not actually
testing the same behavior as at runtime.

Adding the mutators breaks the TestFuzzTarget test as the mutator
changes the variant of the fuzz_smoke_test that is created and so the
test fails to find it.

This fixes the test by correct the variant name.

52767be335 Add support for Rust C libraries.
Adds the ability for rust modules to be compiled as C libraries, and
allows cc modules to depend on these rust-generated modules. This also
means that soong-rust should not have any dependencies on soong-cc aside

 - A bug in libNameFromFilePath that caused issues when library's had
 "lib" in their name.
 - VariantName is removed from rust library MutatedProperties since this

b49fe1bde7 Stop linking libdl.a into static bins
libdl.a has a no-op dlopen, which breaks static libraries that need a real
dlopen. Instead of automatically linking libdl.a into static executables,
make it optional.

Until recently, the libunwind_llvm.a unwinder, used on arm32, needed the
no-op dladdr, but it's now built using -D_LIBUNWIND_USE_DLADDR=0.

The HWASan run-time uses dlsym and dladdr, so add a libdl dependency for
HWASan-built static binaries. We could also remove the dependency from
libclang_rt.hwasan_static-*.a, but this is also easy to do.

64c4395386 Add version to vendor variants
Vendor variant is now divided into several vendor.{version} variants,
depending on their intended usages:

vendor.{BOARD_VNDK_VERSION}: vendor and vendor_available modules
vendor.{PLATFORM_VNDK_VERSION}: VNDK modules in the source tree
vendor.{snapshot_ver}: VNDK snapshot modules

This also affects exported module names from Soong to Make. But to
maintain backward compatibility, ".{BOARD_VNDK_VERSION}" suffix will not
be emitted for modules having version BOARD_VNDK_VERSION, so that vendor
modules still can be referred as-is.

d48f3c3885 soong: Add tests for depending on disabled module
This will check if direct deps of android.Module type is "Enabled()".
Previously, this is checked only if a module calls VisitDeps*()
functions in GenerateAndroidBuildActions().

Most modules call VisitDeps*() in GenerateAndroidBuildActions(),
but some modules don't. For example, "apex" module calls
WalkDepsBlueprint() or VisitDirectDepsBlueprint() since it
exceptionally depends on non-android.Module modules.

Therefore, when an apex module depends on disabled(enabled:false) module,
build fails with panic, which is fixed by this change.

2da19cbc20 Link libc++demangle with libc++ for the device.
libc++demangle provides __cxa_demangle, which used to be a part of
libc++.so but is being moved out to save on resources since very few
libraries need it.

2907459e43 filegroup.path is used to specify the include path for aidl files
filegroup {
    name: "foo",
    srcs: ["srcs/aidl/com/android/**/*.aidl"],
    path: "srcs/aidl",
}

cc_library { // or java_library, etc.
    name: "bar",
    srcs: [":foo"],
}

automatically adds "-Ipath/to/foo/srcs/aidl" when compiling the aidl
files from foo for bar. This allows us to omit aidl include path
when using sources in other places via file group.

da9a463794 Add the cc_fuzz target.
Adds the cc_fuzz target via a cc_fuzz module. Also implements the
libclang runtime interface for the x86 toolchain to allow host-built
fuzzers.

Bug: 137398545

Test: Build a fuzzer (with all topic patches), notice that you now
have a host-built fuzzer :)

380029182c soong: fix wrong link type for VNDKs
Do not rely on 'module.Name()' to decide VNDK link type.
Some prebuilt modules such as libclang_rt_prebuilt_library_shared and
vndk_prebuilt may have different naming schemes.(prefix/suffix)
And llndk_library module has '.llndk' suffix.

Instead, use VNDK-related properties (e.g. vndk.enabled,
vendor_available, etc.).

33b2fb7333 Support using cc_prebuilt_library_shared with cc_library
Allow a cc_prebuilt_library_shared to share the same name as a
cc_library by always creating static and shared variants of
prebuilts so that the variants of the source module are always
a superset of the variants of the target module.

1f086e2f0d Generate VNDK snapshot with Soong except configs
This is the first commit to generate VNDK snapshot with Soong: .so
files, some txt files, and notice files are captured with Soong. As
ld.config.txt is currently in Android.mk and will be deprecated soon,
configs files (and zipping all of artifacts) are still handled with
Makefile.

acee27cd72 Strip libgcc to only keep fallback symbols
We use libgcc as fallback for symbols not present in libclang_rt
builtins, however we didn't know what exact symbols were being used,
some may not be intended to fallback.

Create libgcc_stripped, which only contains unwind symbols from libgcc.
