this is a good compromise between speed and compression

This made the output non binary reproducible across different versions of
zlib.
This reverts commit bce5855afb.

FATE results differ when using the original zlib and zlib-ng.
Since we don't need to test the result from zlib itself, this commit
disables compression on tests for zlib-based codecs, which ends up
giving the same results with both libraries.

The output file (even the filesize) of the recently added
EXR tests depends on the endianness; therefore checksums
of these files must not be part of the ref file. Therefore
this commit adds an option (unused for now) to disable these
checksums on a per-test basis.
In order to avoid having to check twice, the checksum and
the filesize info are moved to immediately follow one another;
this results into updates to the ref files of all lavf-image tests.

Improves rgb -> gray16 conversion
Fixes Ticket3422
The pam and png output files look visually similar, in both cases the
dynamics increase to 0x0 -> 0xfffb.

This makes -t sample-accurate for audio and will allow further
simplication in the future.
Most of the FATE changes are due to audio now being sample accurate. In
some cases a video frame was incorrectly passed with the old code, while
its was over the limit.
