xine-lib fails to build against ffmpeg 4.5

Hi,

xine-lib (both 1.2.11 and a current snapshot) fails to build against a 
snapshot of ffmpeg that will become ffmeg 4.5.

ff_video_decoder.c:64:11: fatal error: libavcodec/vaapi.h: No such file 
or directory
    64 | # include <libavcodec/vaapi.h>
       |           ^~~~~~~~~~~~~~~~~~~~

vaapi.h was deprecated a long time ago and was removed in the following 
commit:
https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/e3d993fab0ad4255dffd10a794fc5e1bd37047b7

Also :
ff_audio_decoder.c: In function 'ff_audio_init_codec':

       |                   ^
