This was unnecessary in the past, when -nodefaultlibs was used while
linking, but that changed with
aosp/I722bd6596a1f3f5819f2767c29c0fa1e8b3ec0e8.

apex_available property can be appended differently per the linkage
type. This will be used to restrict certain libs (e.g.
libc_malloc_debug) to an APEX while allowing them to be statically
linkable from platform for testing purpose.

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.

This change reverts following three changes to remove the no_apex
property. no_apex: true is equivalent to apex_available:
["//apex_available:platform"].
Revert "fix: "no_apex" can be put in defaults"
This reverts commit cc372c5b1d.
Revert "Add no_apex check for static library"
This reverts commit 2db7f46d0c.
