The APEX dependency is more correctly tracked. Previously, the
dependency was tracked while we gather modules that will be installed to
an APEX. This actually was incorrect because we skipped many dependency
types that we don't need to follow to gather the modules list, such as
the headers dependency.
Now, the dependency is tracked directly when a module is mutated for an
APEX. In other words, if a module is mutated for an apex X, then the
module will appear in the X-deps-into.txt file.
This change also changes the format of the txt file. It now clearly
shows why a module is included in the APEX by showing the list of
modules that depend on the module.

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.

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.

cc_library_static {
name: "libfoo",
shared_libs: ["libbar"],
}
cc_library {
name: "libbar",
}
If libfoo is part of an APEX, then libbar is no longer considered as a
member of the APEX, because it isn't actually linked to libfoo.
To distinguish such a shared lib dependency from a static library from a
shared lib dependency from a shared library, a new dep type
SharedFromStaticDepTag is introduced. It is treated exactly the same as
SharedDepTag, except when we determine whether a dependency is crossing
the APEX boundary or not.
This allows us to check the apex_available property more correctly.
Previously, modules were incorrectly considered as being used for an
APEX due to the shared lib dependency from a static lib.
As a good side effect, this also reduces the number of APEX variants.
Specifically, on aosp_arm64, the number of the generated modules were
reduced from 44745 to 44180.

(cherry picked from commit 931b676a69)
Change-Id: I899ccb9eae1574effef77ca1bc3a0df145983861
This change fixes a bug that apex_available is not enforced for static
dependencies. For example, a module with 'apex_available:
["//apex_available:platform"]' was able to be statically linked to any
APEX. This was happening because the check was done on the modules that
are actually installed to an APEX. Static dependencies of the modules
were not counted as they are not installed to the APEX as files.
Fixing this bug by doing the check by traversing the tree in the method
checkApexAvailability.
This change includes a few number of related changes:
1) DepIsInSameApex implementation for cc.Module was changed as well.
Previuosly, it returned false only when the dependency is actually a
stub variant of a lib. Now, it returns false when the dependency has one
or more stub variants. To understand why, we need to recall that when
there is a dependency to a lib having stubs, we actually create two
dependencies: to the non-stub variant and to the stub variant during the
DepsMutator phase. And later in the build action generation phase, we
choose one of them depending on the context. Also recall that an APEX
variant is created only when DepIsInSameApex returns true. Given these,
with the previous implementatin of DepIsInSameApex, we did create apex
variants of the non-stub variant of the dependency, while not creating
the apex variant for the stub variant. This is not right; we needlessly
created the apex variant. The extra apex variant has caused no harm so
far, but since the apex_available check became more correct, it actually
breaks the build. To fix the issue, we stop creating the APEX variant
both for non-stub and stub variants.
2) platform variant is created regardless of the apex_available value.
This is required for the case when a library X that provides stub is in
an APEX A and is configured to be available only for A. In that case,
libs in other APEX can't use the stub library since the stub library is
mutated only for apex A. By creating the platform variant for the stub
library, it can be used from outside as the default dependency variation
is set to the platform variant when creating the APEX variations.
3) The ApexAvailableWhitelist is added with the dependencies that were
revealed with this change.

Otherwise binaries under:
prebuilts/gcc/linux-x86/host/x86_64-w64-mingw32-4.8/bin/
are being invoked.
https://sourceware.org/binutils/docs-2.33.1/binutils/windres.html
states:
When windres reads an rc file, it runs it through the C preprocessor first.
Use the `--preprocessor` flag to specify the exact command to run. The
args to the preprocessor get wiped out when setting that flag, so
`-E -xc-header -DRC_INVOKED` must be re-passed, else clang will error as
it tries to invoke ld.
