Currently, for an API symbol to be accessible to APEXes, it needs to be
marked as either # systemapi or # apex. It was originally just # apex,
but we added # systemapi to clearly identify the origin of the APIs.
The intended use is
* #apex is for APEX-visible symbols that are defined in an APEX
* #systemapi is for APEX-visible symbols that are defined in the
platform (the non-updatable part)
This intention is documented build/soong/docs/map_files.md, but isn't
enforced at all.
With b/239274367, this is now enforced and therefore the #apex tags in
the platform library are replaced with `#systemapi`
This change does not alter any functionality.

Vendor APEX section should not separate SPHAL in generic, and also
default namespace does not contain vendor libs in the scope. This change
updates libvndksupport to check 'vendor' namespace when there is no
sphal namespace for vendor APEX section case.

Instead of assuming a module with the .llndk suffix exists, add an
llndk_stubs property to every cc_library module that has a
corresponding llndk_library. Also rename the llndk_library to have

These weak symbols are no longer necessary because we no longer
need to statically link libvndksupport.
Furthermore, these symbols are not really optional when libvndksupport is
dynamically linked. When the library is linked with --as-needed the linker
may drop the reference to libdl_android.so, which leads to a failure to boot.

The APIs that are tagged with # vndk are actually for LLNDK libraries.
Although LLNDK is part of VNDK, calling those APIs 'vndk' has given
users a wrong perception that the APIs don't need to be kept stable
because that's the norm for most of the VNDK libraries that are not
LLNDK.
In order to eliminate the misunderstanding, rename the tag to 'llndk' so
that people introducing new such API will realize what they are signing
themselves up for.

Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).
However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.
All needed modules have to explicitly indicate if they may be used as part
of translated binary build.
This change enabled native bridge support for libvndksupport
a dependency of libutils greylisted library (available for apps
targeting Android version < N).

Init is executed without ld.config.<ver>.txt loaded (since sysprop
service isn't up in order for it to read ro.vndk.version and know <ver>). It uses the hard-coded
namespaces in the linker and therefore, does not know about the vndk namespace. That does not mean
it is not a system process.

In preparation for cleaning up conditionally compiled VNDK libraries,
we need a function that determines if the current process is running in
the system process or the vendor process.

From O, libutils.so is loaded twice. Once in the default namespace and
once in the sphal namespace for vendor libs. However, since the
framework only communicates with the instance loaded in the default
namespace, report_sysprop_change() event is not notified to the instance
in sphal namespace. This causes ATRACE to not work for vendor libs
loaded in sphal namespace.
So, the instance loaded in default namespace now explicitly redirects
the event to the other instance.
