When the stubs variant of a library is dependend by a platform component
and the library is included in one or more APEX, the library is not
installed to the platform, because it is provided by APEX.

When a native module is built for an APEX and is depending on a native
library having stubs (i.e. stubs.versions property is set), the stubs
variant is used unless the dependent lib is directly included in the
same APEX with the depending module.
Example:
apex {
name: "myapex",
native_shared_libs: ["libX", "libY"],
}
cc_library {
name: "libX",
shared_libs: ["libY", "libZ"],
}
cc_library {
name: "libY",
stubs: { versions: ["1", "2"], },
}
cc_library {
name: "libZ",
stubs: { versions: ["1", "2"], },
}
In this case, libX is linking to the impl variant of libY (that provides
private APIs) while libY is linking to the version 2 stubs of libZ. This is
because libY is directly included in the same apex via
native_shared_libs property, but libZ isn't.

Shadow call stack (SCS) is a security mitigation that uses a
separate stack (the SCS) for return addresses.
The effect of setting sanitize.scs on a shared library is to build
the library and all of its static library dependencies with SCS. This
is similar to CFI and the other sanitizers.

A cc_library or cc_library_shared can be configured to have stubs
variants of the lib.
cc_library_shared {
name: "libfoo",
srcs: ["foo.cpp"],
stubs: {
symbol_file: "foo.map.txt",
versions: ["1", "2", "3"],
},
}
then, stubs variants of libfoo for version 1, 2, and 3 are created
from foo.map.txt. Each version has the symbols from the map file where
each symbol is annotated with the version that the symbol was introduced
via the 'introduced=<ver>' syntax. The versions don't need to be in sync
with the platform versions (e.g., P for 28). The versions are local to
the library.
For another library or executable to use the versioned stubs lib, use
the new 'name#ver' syntax to specify the version:
cc_binary {
name: "test",
....
shared_libs: ["libFoo#2"],
}
Internally, a new mutator 'version' is applied to all cc.Module objects.
By default, a variant named 'impl' is created for the non-stub version.
If the versions property is set, additional variations are created per a
version with the mutable property BuildStubs set as true, which lets the
compiler and the linker to build a stubs lib from the symbol file
instead from the source files.
This feature will be used to enforce stable interfaces among APEXs. When
a lib foo in an APEX is depending on a lib bar in another APEX, then bar
should have stable interface (in C lang) and foo should be depending on
one of the stubs libs of bar. Only libraries in the same APEX as foo can
link against non-stub version of it.

ApexModule is the interface for APEX-aware modules. The module type apex
uses the interface to get APEX-specific information from other modules,
such as the list of APEXs that a module should be built for.
A module that is included in an APEX will be built specificaly for the
APEX. This is especially required for shared libraries; we shouldn't
just copy the artifacts built for platform, because they may be linking
against private (=unstable) symbols that are not available to APEXs
which are basically unbundled.
This CL, as a first step, makes cc.Module an APEX-aware module type.

This CL fixes a bug that when a module is configured as 'vendor: true' &&
'recovery_available: true', the link type of the recovery variant of the
module is incorrectly set to 'native:vendor'. This was because,
androidmk.go emits 'LOCAL_PROPRIETARY_MODULE := true' whenever
Proprietary property is set to true, regardless of whether it is a
recovery variant or not. This in turn makes LOCAL_USE_VNDK := true for
the module which in turn causes the link type to be 'native:vendor'.
Fixing the bug by resetting the properties like Proprietary, Vendor,
Soc_specific, etc. for the recovery variants.

This is a new sanitizer similar to ASan, but with a few differences
from the build system perspective:
* Only runs on AArch64.
* Supports static binaries.
* Bionic itself will be built with HWASan.
* Does not have any "if a library is sanitized than the binary must
be, too" requirements unlike ASan. Even better, individual static
libraries can be freely sanitized or not. We propagate "nosanitize"
from binaries to static libraries anyway, because otherwise there
is no good way to disable hwasan on a binary as a whole.
Same a CFI, we export a list of sanitized static libraries to make.
In fact, we export separate lists for vendor and regular libraries,
because it is possible for one to be sanitized without the other
(i.e. there can be mylib.hwasan.vendor w/o mylib.hwasan or vice
versa).

Fixed a bug that recovery variant of a module is not created on 32-bit
targets. The bug was happening because the creation of the recovery
variant relied on DevicePrefer32BitExecutables() which returns false

device that is returned by DevicePrimaryArchType().

To save space in the recovery partition, modules installed to the
partition are restricted to be built in the first architecure (i.e.,
32bit for 32bit-only device or when TARGET_PREFER_32_BIT is true, and
64bit otherwise).
Most notably, this change removes the 32-bit variant of the linker
(about 1MB). The linker was installed regardless of whether there is a
32-bit executable or not. Now, the unnecessary linker is not installed

This commit adds `runtime_libs` to cc_binary and cc_library.
Similar to the `required` property, if a module specifies the
`runtime_libs` properties and it is installed, then the modules
specified in `runtime_libs` will be installed as well.
Differnt from the `required` property, if a module is using VNDK and the
module names specified in `runtime_libs` are resolved to the modules
with both core and vendor variants, then '.vendor' will be appended to
those module names.
For example, if `libb` is vendor_available and `libd` is a vendor lib,
then LOCAL_REQUIRED_MODULES will contain `libb.vendor` (instead of
`libb`).

double_loadable is a property that tells whether a module is capable or
being loaded with other instance (possibly an older version) of the same
module in the same process. Currently, a shared library that is a member
of VNDK can be double loaded in a vendor process if the library is also
a dependency of an LLNDK library. Such libraries now must be explicitly
marked as `double_loadable: true` by the owner, or the dependency from
the LLNDK lib should be cut if the lib is not designed to be double
loaded.
