dsputil: remove duplicate or unused functions.

dct_bits is never set except in h264, where it is never used, thus
remove it. Then, remove all functions that were set based on non-zero
(32) values for dct_bits. Lastly, merge 9-14 bpp functions for get_pixels
and draw_edge, which only care about pixel storage unit size, not actual
bits used (i.e. they don't clip).

Revert "lavfi/ebur128: fix format negociation for output."

This reverts commit 9efcfbed9dd64679145f5f39d9a812dfeea97172.

All the shame on me; this commit is actually causing more problems
(broken outputs but also crashes) than it was solving.

lavfi/ebur128: fix format negociation for output.

Before this change, the audio input and output formats are set
independently, so the lavfi negociation could pick different settings
for the input and output. This is particularly true for the channel
layout settings, where multiple choices were available.

Fixes Ticket2342.

lavfi/thumbnail: support flushing.

This makes possible the raise of one picture if the input has less than
the number of frames to analyze.

Fixes Ticket1992.

tiff: fix handling of metadata with refcounted frames

Since the conversion to refcounted frames, the tiff decoder
only wrote the metadata into its internal "picture" in its own context,
never exposing the metadata to the user, and eventually leaking the
metadata.

Instead, properly store the metadata directly into the frame being decoded into.

yadif: restore speed of the C filtering code

Always use the special filter for the first and last 3 columns (only).

Changes made in 64ed397 slowed the filter to just under 3/4 of what it
was.  This commit restores the speed while maintaining identical output.
