x86 and ARM DSP modified by simply moving the multiple calls from vc1dec
to the DSP code. Decoding improvements should only occurs because of the
compiler actually able to unroll more.

f6774f905f mpegvideo: operate with pointers to AVFrames instead of whole structs 
The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().

ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.

NULL pointer checks are added to ff_thread_release_buffer() stub function.
