vaapi: minor changes

This is for relicensing. Some of this code is loosely based on
vo_vaapi.c from the original MPlayer-vaapi patches. Most of the code has
changed, and only the initialization code and check_status() look
remotely similar. The initialization code is changed to be like Libav's
(hwcontext_vaapi.c). check_va_status() is just a C idiom, but to play it
safe, we'll either drop it from LGPL code (or recreate it).

vaapi.c still contains plenty of code from the original patches, but the
next commits will move them out of the LGPL code paths.
