Subject: vaapi: replace image pool implementation with mp_image_pool

Although I at first thought it would be better to have a separate
implementation for hwaccels because the difference to software images
are too large, it turns out you can actually save some code with it.

Note that the old implementation had a small memory management bug. This
got painted over in commit 269c1e1, but is hereby solved properly.

Also note that I couldn't test vf_vavpp.c (due to lack of hardware), and
I hope I didn't accidentally break it.
