This changes the default Java language level from 8 to 9, i.e. javac
invocations now use -source 1.9 -target 1.9.
The environment variable EXPERIMENTAL_JAVA_LANGUAGE_LEVEL_9=false is
added to switch back to the language level 8 behaviour. (Previously,
setting that variable to true was required to opt in to language level
9.)

We rely on a weird, GNU specific behaviour of objcopy:
$ aarch64-linux-android-objcopy -w libgcc.a stripped.a --strip-unneeded-symbol=*
$ llvm-nm --defined-only stripped.a | grep multi
0000000000000000 T __multi3
$ aarch64-linux-android-objcopy -w libgcc.a stripped.a --strip-unneeded-symbol=* --keep-symbol=FOO
$ llvm-nm --defined-only stripped.a | grep multi
llvm-objcopy has a different, more consistent behaviour that does not
mark exported symbols as unneeded when "--keep-symbol" flag exists.
However this behaviour will leave most symbols not deleted in the
libgcc_stripped library.
Revert the change while I'm implementing an alternative solution.

This was unnecessary in the past, when -nodefaultlibs was used while

`m <sdk_name>` generates two scripts each of which is use to update the
current snapshot of the SDK and to freeze ToT as a new version,
respectively. Executing the scripts will copy necessary files (stub
libraries, AIDL files, etc.) along with Android.bp into the ./<apiver>
directory under the directory where the sdk is defined.
This change also introduces a new module type 'sdk_snapshot' that
represents a snapshot of an SDK. It will be auto-generated by the above
scripts, so developers are not expected to write this manually.
The module type 'sdk' is now used to simply specify the list of modules
that an SDK has.
Finally, this change changes the version separator from '#' to '@'
because '#' confuses Make.

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.

(cherry picked from commit e36f52754f)
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.

APK in a flattened APEX is installed as 'ETC' class module, instead of
the 'APP' class. This is to prevent Make from doing app-specific
amendments (e.g. such as adding module name after my_module_path)
to the paths and filenames which are all correctly set in the Soong
side.
Test: add `installable:true` to development/samples/Snake/Android.mk
and add 'Snake' to the `apps` property of an APEX. The build is
successful.
Test: build the APEX on a device with TARGET_FLATTEN_APEX=true
The APK is at system/apex/<apexname>/app/Snake/Snake.apk

This allows droidstubs to use the same system modules to create the
stubs that will be used to compile them. It improves consistency and
avoids droidstubs having to duplicate the libraries that make up the
system modules on its libs property.
Adds systemModules() to the sdkContext which allows consistent error
checking behavior between droidstubs and java_library.

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.
