If fuzzer coverage sanitized shared libraries are not deployed - we shouldn't
break users during dynamic link time. I need to think more about how we
should solve this problem in earnest, but for now let's just disable
static linkage of libc++ on device.

With __ANDROID_APEX_<NAME>__ definition, native modules may have
different behavior when it is built for a specific apex module.
Previously, the name is passed as value of definition __ANDROID_APEX__
like -D__ANDROID_APEX__=com.android.foo. But it is difficult to do
conditional compilation with it.
Now, since the name is incorporated into definition itself, it gets
easier to set #ifdef condition.

Older VNDK libraries are provided as vndk_prebuilt_shared modules. Those
are added to corresponding VNDK APEX as dependencies.
With VNDK APEX installed, VNDK libs are unnecessary. By the way, since
there can be vendor modules which depend on VNDK libs, Make targets are
still emitted with UNINSTALLABLE=true.
Android.mk has additional modules for vndk libraries which are named
with apex name as suffices. For example, if libfoo is a vndk library,
then libfoo.vendor is its vendor variant and it would be in
/system/lib/vndk. But with vndk apex, it has additional
libfoo.com.android.vndk.current variant.

Fuzz targets currently have dependencies on multiple libclang_rt runtime
libraries when building with ASan/HWAsan on device. This is an error.
This happens as Soong adds the dependency on the ASan/HWASan shared
runtime library. These libraries should provide the required UBSan
components. The clang driver was previously being passed
-fsanitize=fuzzer-no-link at link time, and as it doesn't know about the
already-established dependency on ASan/HWASan, it mistakenly thinks that
there is not runtime providing the UBSan components.
This patch fixes that problem by not adding -fsanitize=fuzzer-no-link to
the link-time flags.
This revealed a underlying issue in the upstream runtime compilation.
Android uses emulated TLS, which changes the symbol names from
<my_symbol_name> to __emutls_v._<my_symbol_name>. In particular, this
fails to account for the '__sancov_lowest_stack' symbol, as it no longer
matches the linker script rule for '__sancov*', and the symbol is no
longer exported in the shared library variant of ASan/HWASan.
This patch works around the discovered issue, which is being tracked in
the linked bug. It disables stack depth instrumentation, and we no
longer depend on this symbol. This means we get a missing sanitizer
coverage feature when fuzzing, but shouldn't be too detrimental.

Host builds using libc++ used -nodefaultlibs to turn off the default
C++ runtime, and then added back all the other necessary libraries.
Clang supports -nostdlib++ since https://reviews.llvm.org/D47115
that removes the C++ runtime without affecting the other default
libraries. Use -nostdlib++, and remove the lists of default
libraries.

Create a new type InstallPath that is similar to OutputPath to
differentiate intermediates output paths from installed output
paths.
RelPathString is a poorly defined, undocumented function that is
primarily used to get an install path relative to out/soong to
generate an equivalent install path for Make relative to $(OUT_DIR).
Move it to InstallPath for now, and fix the one remaining user on
OutputPath.
Add a method to create an NDK install path so that ndk_sysroot.go
doesn't have to do it manually with PathForOutput.

Android builds by default put artifacts into out/ subdirectory of
the source tree, causing the extractor to record their names as
relative. The indexer considers such files as sources, which is wrong.
Fortunately, the extractor can be fed a set of filename rewriting
rules (see build/tools/vnames.json).
Also, undo previous unsuccessful attempt use to absolute path for the
output directory to distinguish between source code and artifacts.

Without this change, we can end up failing to sanitize parts of libraries
that are compiled as cc_objects, such as bcm_object.o in boringssl. This
is normally harmless (except that the sanitizer would fail to detect bugs
in unsanitized code), however boringssl in particular needs to be compiled
with HWASAN enabled in all translation units in order to avoid link errors
with newer toolchains that support HWASAN global instrumentation.

Adds the `make fuzz` build rule. This offers a few features on top of
`make haiku`:
1. Identifies all fuzz targets through the build system, rather than
having to maintain a golden file.
2. Packages now exist in out/soong/ and are packaged on a per-architecture
basis. Packages also now contain fuzzer seed corpus && dictionary.
3. This gives us further extension options:
- Packaging shared libraries for shared library fuzzing.
- Presubmit tests for fuzzing. Each fuzz target could be made into a
regression test by adding the crash testcase to the corpus. We can
also ensure that example_fuzzer finds a bug with an ASan report as a
presubmit smoke test.

This change introduces a new module type named 'sdk'. It is a logical
group of prebuilt modules that together provide a context (e.g. APIs)
in which Mainline modules (such as APEXes) are built.
A prebuilt module (e.g. java_import) can join an sdk by adding it to the
sdk module as shown below:
sdk {
name: "mysdk#20",
java_libs: ["myjavalib_mysdk_20"],
}
java_import {
name: "myjavalib_mysdk_20",
srcs: ["myjavalib-v20.jar"],
sdk_member_name: "myjavalib",
}
sdk {
name: "mysdk#21",
java_libs: ["myjavalib_mysdk_21"],
}
java_import {
name: "myjavalib_mysdk_21",
srcs: ["myjavalib-v21.jar"],
sdk_member_name: "myjavalib",
}
java_library {
name: "myjavalib",
srcs: ["**/*/*.java"],
}
An APEX can specify the SDK(s) that it wants to build with via the new
'uses_sdks' property.
apex {
name: "myapex",
java_libs: ["libX", "libY"],
uses_sdks: ["mysdk#20"],
}
With this, libX, libY, and their transitive dependencies are all built
with the version 20 of myjavalib (the first java_import module) instead
of the other one (which is for version 21) and java_library having the
same name (which is for ToT).
