Useful to add or update fate tests.

This is needed in order for the FLV demuxer not to detect a codec change when
using the "flv_metadata" option.

There is no noticable benefit for such precision.

Current dithering only uses the first 4 instead of the whole 8 random values.

Current code divides before increasing precision.

Also reduce upper bound for strength from 255 to 64.  This will prevent
an overflow in the SSSE3 and MMX filter_line code: delta is expressed as
an u16 being shifted by 2 to the left. If it overflows, having a
strength not above 64 will make sure that m is set to 0 (making the
m*m*delta >> 14 expression void).

A value above 64 should not make any sense unless gradfun is used as
a blur filter.

First DC is only used once otherwise. This also makes the code
consistent with ASM versions.

- Make MultiByteToWideChar fail when it encounters invalid encoding.
  Without this, invalid characters might just be skipped
- When MultiByteToWideChar fails, assume the file name is in CP_ACP
  and open it via normal open function, even when the file will be
  written
- When malloc fails return error instead of crashing

In order to match Linux behaviour better our Windows-specific
open() replacement should disable Windows default file locking.

This makes standalone compilation of the eatqi decoder
succeed. The dependency comes from the shared mpeg12dec.o file.

This fixes standalone compilation of the msmpeg4v2, msmpeg4v3
and wmv2 encoders, that previously failed to link due to the
decoder codepaths requiring error_resilience.

This makes the DCA parser and decoder independent.

Fixes linking when only a subset of the deprecated vdpau decoders is
enabled.
