split libandroid.so

- ANativeWindow (native_window.h) and
  AHardwareBuffer (hardware_buffer.h) now live
  in libnativewindow.so, which is a vodka library.

- libandroid.so still provide those symbols
  via a static library version (libnativewindow.a)

- removed libbinder dependency as well

Test: compiled & booted
