This patchset is a mix of mpegvideo-related patches. The second half
(beginning with avcodec/ituh263dec: Simplify AIC handling) mostly has a
theme, namely improving dc_val and ac_val handling in mpegvideo. The first
is just other stuff which I found while investigating the latter.
Andreas Rheinhardt (47):
avcodec/mpeg4videodec: Don't zero blocks twice
avcodec/rv10: Perform RV20 initialization during init
avcodec/rv10: Perform RV20 check only for RV20

avcodec/ituh263dec: Remove redundant store
avcodec/ituh263enc: Don't use array unnecessarily
avcodec/ituh263enc: Fix indentation
avcodec/mpeg12dec: Don't store block_last_index unnecessarily

avcodec/mpegvideo: Provide alignment hint to compiler
avcodec/mpegvideo: Don't reset AC values of upper-left luma block
avcodec/mpegvideo: Combine stores
avcodec/mpeg4video: Don't use ac_val[1], ac_val[2] when cleaning
buffers
avcodec/mpegvideo: Only use a single ac_val pointer
avcodec/mpegvideo: Allocate ac_val jointly
avcodec/mpegvideo: Zero-init mbintra_table
avcodec/mpegvideo: Only keep MpegEncContext.dc_val[0]
avcodec/vc1: Only keep mb_type[0]
avcodec/mpegvideo: Allocate dc_val for each encoder slice
avcodec/{ituh263,mpeg4video}enc: Simplify out-of-slice DC prediction
avcodec/mpeg4video: Move ff_mpeg4_pred_dc() to decoder
avcodec/ituh263enc: Simplify encoding umotion vectors
avcodec/mpegvideo: Reduce stack usage when copying MpegEncContext
avcodec/mpeg4videoenc: Fix data race when using AC prediction
