2768f7e4fe sparc: VIS mnemonics 
Currently, if VIS is enabled by configure, it will also be enabled at
run-time regardless of its support in the hardware. Thus, masking VIS
usage as it is done in vis.h by constructing binary instructions is
pointless. Using normal VIS mnemonics in inline assembly allows to take
advantage of automatic register allocation, gets rid of register
variables, which are unsupported by suncc for SPARC, and improves code
readability.

98c292a7a8 Adding support for encoding VP8 Alpha 
This patch adds support for encoding VP8 files with alpha. The alpha channel
is encoded separately and the output is placed in AVPacket's side_data. The
muxer then muxes it into the BlockAdditional element of the matroska container.
More details on spec here: http://goo.gl/wCP1y

259af1b923 mpegvideo: allocate sufficiently large scratch buffer for interlaced vid 
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer

For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.

This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.

22c7784f60 adpcm_thp: Allow the use of extradata for the adpcm table 
There are several containers that support adpcm_thp (Also known as Gamecube DSP)
streams, but only thp files contain the coeff table and previous sample inside
each frame.
Some don't even contain previous sample information at all.

This change will make it easier to implement demuxers for said containers
without having to create a new decoder.

Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.
