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.
Bug: 119423884
Test: Add a dummy VNDK library that prints different string in system
vs vendor process. Use the library in different processs and
check the output.

... if they are not available. Use weak symbols and do not call the
following functions when they are not defined:
* android_dlopen_ext
* android_get_exported_namespace
Test: links

In vendor process, libvndksupport must look for "default" namespace,
instead of "sphal" namespace to open hal libraries.

If no 'sphal' namespace exist, the sphal library may be found in
current namespace.
Change the log level and message to note this.

Test: Check log message for vndksupport tag.

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.

Test: start an app, run 'adb shell atrace gfx --stream'. atrace from the
graphics driver are visible.

Instead of looking up default namespace for the failure of loading
sphal libs, report failure. This is only for the devices that have
sphal namespace.

libvndksupport is a new LL-NDK library that provides vendor-visible APIs
for platform-only functionalities of other LL-NDK libraries. Currently,
it provides android_(load|unload)_sphal_library which abstracts the
platform-only APIs of libdl (android_get_exported_namespace, etc.)
