When building with two OSes of the same class (Host, etc) enabled,
independently produce variants of each module for each OS, instead of
making `compile_multilib: "first"` select just one of the OSes.
My use case this is for Linux + LinuxBionic, which are both considered
Host class, but this would also applied if we wanted to generate rules
for Linux+Darwin, or some combination of firmware bits (either in
addition to Android in the Device Class, or multiple firmwares in a new
Class)

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).

Normally, when building with VNDK, platform modules are not allowed to
link against vendor libraries, because the ABI of the vendor libraries
are not guaranteed to be stable and may differ across multiple vendor
images.
However, the vendor public libraries are the exceptions. Vendor public
libraries are vendor libraries that are exposed to 3rd party apps and
listed in /vendor/etc/public.libraries.txt. Since they are intended to
be exposed to public, their ABI stability is guaranteed (by definition,
though it is up to the vendor to actually guarantee it).
This change provides a way to make a vendor lib as public by defining a
module of type 'vendor_public_library' with a map file that enumerates
public symbols that are publicized:
cc_library {
name: "libvendor",
proprietary: true,
...
}
vendor_public_library {
name: "libvendor",
symbol_file: "libvendor.map.txt",
}
This defines a stub library module named libvendor.vendorpublic from the
map file. `shared_libs: ["libvendor"]` is redirected to the stub library
when it is from the outside of the vendor partition.

When a lib is explicitly marked as `vendor_available: false`, then it
can't be directly depended by a vendor lib which is installed to /vendor
partition. This is to hide some VNDK libs (including llndk) from vendors
so that platform owners can have a freedom of modifying their ABI
without breaking vendors.
In addition, the list of the private libs are exported to the make world
as VNDK_PRIVATE_LIBRARIES.
Also, fixed a bug that allowed a vndk lib to link against to vendor
library (or vendor variant of a system lib) if the lib is prebuilt.

Adds the SANITIZE_TARGET=integer_overflow build option to apply signed and

Soong side of the build option.

Nothing changes if BOARD_VNDK_VERSION isn't set.
When the VNDK is enabled (BOARD_VNDK_VERSION in Make), this will split
/system and /vendor modules into two different variant spaces that can't
link to each other. There are a few interfaces between the two variant
spaces:
The `llndk_library` stubs will be available in the /vendor variant, but
won't be installed, so at runtime the /system variant will be used.
Setting `vendor_available: true` will split a module into both variants.
The /system (or "core") variant will compile just like today. The
/vendor ("vendor") variant will compile against everything else in the
vendor space (so LL-NDK instead of libc/liblog/etc). There will be two
copies of these libraries installed onto the final device.
Since the available runtime interfaces for vendor modules may be
reduced, and your dependencies may not expose their private interfaces,
we allow the vendor variants to reduce their compilation set, and export
a different set of headers:
cc_library {
name: "libfoo",
srcs: ["common.cpp", "private_impl.cpp"],
export_include_dirs: ["include"],
target: {
vendor: {
export_include_dirs: ["include_vndk"],
exclude_srcs: ["private_impl.cpp"],
srcs: ["vendor_only.cpp"],
},
},
}
So the "core" variant would compile with both "common.cpp" and
"private_impl.cpp", and export "include".
The "vendor" variant would compile "common.cpp" and "vendor_only.cpp",
and export "include_vndk".

Shared libraries are now installed to different directories depending on
their types.
* NDK libraries: /system/lib/ndk
* VNDK libraries: /system/lib/vndk
* VNDK-ext libraries: /system/lib/vndk-ext
* Framework-only libraries: /system/lib
* Vendor-only libraries: /vendor/lib
* Same-process HALs: /vendor/lib/sameprocess
In addition, a new module type vndk_ext_library is added. It is almost
identical to cc_shared_library but it introduces another attribute
'extends'. This is use to reference the vndk library that this vndk-ext
library is extending.
For example, in order to extend a vndk library libFoo:
cc_library {
name: "libFoo",
srcs: [...]
}
---------------------
vndk_ext_library {
name: "libFoo-extended",
srcs: [...]
extends: "libFoo"
}
Then, libFoo will be installed as /system/lib/vndk/libFoo.so and
libFoo-extended will be installed as /system/lib/vndk-ext/libFoo.so.
Note that file name of the latter is libFoo.so, not libFoo-extended.so:
file name of an extending module is automatically set to that of the
extended module.
