Andreas Rheinhardt 5106fe85f7 avcodec/h261dec: Initialize IDCT context during init 
Before 998c9f15d1, initializing an
MpegEncContext's IDCT parts occured in ff_mpv_common_init() and this
has been called in h261_decode_frame(), not h261_decode_init().

Yet said commit factored this out of ff_mpv_common_init() and therefore
there is no reason any more not to set this during init as this commit
does.
