Add small user-event abstraction interface.

Preparation for future UI frontend/backend separation.

This is done to ensure that the code under android/skin/ does not depend
on any QEMU-specific header. We achieve this by adding a new abstract header
"user-events.h" and one QEMU-specific implementations for the functions
defined here.

This also modifies console.h and vl-android.c to make them closer to
upstream (by removing Android-specific changes).

+ fix Makefile.android to always build SDL from sources in standalone mode.
