Ratchanan Srirattanamet d0ffcb46df androidmedia: call all static_init() functions from single entry point 
This allows the implementations to do custom logic behind the hood. For
example, when NDK implementation is added, the entrypoint can chooses to
statically initialize the NDK implementations or the JNI one.
