Jayant Chowdhary a229d3e23e Special case init for android_is_in_vendor_process.
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.

Bug: 124128212

Test: Boot up device with selinux enforced, use camera to take pictures/ record videos (sanity)
Test: Watch movies on youtube (sanity)

Vic Yang a117f25b4e libvndksupport: Add android_is_in_vendor_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.

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.

Yifan Hong 1ccdb7d92a libvndksupport: do not use functions from android/dlext.h
... 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
Test: boots

Justin Yun 090b593a8d Make libvndksupport look for default namespace as well.
In vendor process, libvndksupport must look for "default" namespace,
instead of "sphal" namespace to open hal libraries.

Justin Yun a34bd0561d libvndksupport: Change log level and message.
If no 'sphal' namespace exist, the sphal library may be found in
current namespace.
Change the log level and message to note this.

Justin Yun 17baed1012 libvndksupport: Do not lookup default namespace for sphal failure
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.

Jiyong Park 7130e13262 add libvndksupport
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.)
