Do not rely on get_buffer initializing them.

Changes yadif tests (off by one in one border pixel), because yadif
reads from those uninitialized lines.

The bottom line was invalid before.

Setting it to zero (instead of 128, as the default get_buffer() does)
also produces more correctly-looking output.

The FATE sample contains some pixels with value 0, but the palette
stored in the file contains only values from 16 up. Because the default
and cmdutils get_buffer() initialize the data to 0x80, they appear as
gray dots.
After this commit they change to black dots, which is probably still
incorrect but less visible and doesn't rely on get_buffer() initializing
the data.

We have to make some symetric changes elsewhere as this increases
the precission with which samples are stored.

Do not assume that frame dimensions are mod16 (or that height is mod32

Add support to an if/else construct, simplify logic in expressions.

This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.

Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).

Add some additional checks for EOF and print error messages on an incomplete
header or packet.

FATE reference updated for id-cin-video due to the demuxer no longer
returning a partial video packet at EOF.

The mp=pp filter was removed and replaced with a native implementation,
so the dependency on CONFIG_MP_FILTER stands no more.

Also re-enable the FATE test.

Snow is a toy codec with no real-world use and horrible code.

The filter has been added recently and does not yet pass tests on all platforms.
It should not be included in the tests in the release until it works.
