d4fdaafdb7 Always write all colours for animated gif files, including transparent ones.
This fixes the colour of the transparent background (as seen with ffplay),
and makes the background of some non-keyframes transparent that was
incorrectly shown as opaque for some samples.

45635885e4 mpegvideo: increase edge_emu_buffer size for VC1
The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma
and needs more space. That was not a problem before f1d8763a02b5fce
since the size for edge_emu_buffer was always calculated with 2 byte per
pixel since the linesize was not known.

Fixes occasionally fate errors in vc1_sa10143.

f1d8763a02 mpegvideo: allocate scratch buffers after linesize is known
Since we can't know which stride a custom get_buffer() implementation is
going to use we have to allocate this scratch buffers after the linesize
is known. It was pretty safe for 8 bit per pixel pixel formats since we
always allocated memory for up to 16 bits per pixel. It broke hoever
with cmdutis.c's alloc_buffer() and high pixel bit depth since it
allocated larger edges than mpegvideo expected.

Fixes fuzzed sample nasa-8s2.ts_s244342.

It is not posible to call get_buffer during frame-mt codec

sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains
multiple slices.
