This reverts parts of d6d5ef5534d582, that didn't work right. (The
tests that were added failed on big endian, and the output looked
garbled on little endian as well.)

This is due to the fact that the intermediate scaling values (from
e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and
thus requires a separate output function, while yuv2gbrp_full_X_c
only interprets it as int16_t.

This replaces a large number of checks for the second field by
fixing the pointers when they are setup

This should also fix I/BI field pictures

Changes checksums for vc1_sa10143, the file becomes slightly closer
to what the reference decoder outputs

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.

Use a noise range of -0.707 to 0.707 instead of -0.5 to 0.5

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).

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.

Force commands to specify the name of the test to run. This simplifies
extending the function with a new parameter, which will be done in a
following patch.
