Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.

From 253 to 51 cycles on Arrandale and Win64.
44 cycles on SandyBridge.

delta is in samples, not bytes. Also the sample format is not guaranteed
to be planar.

This makes linking succeed for tools that include config.h but
don't link to libavutil.

The indirection was used to abstract from the different -regression.sh
scripts. Now that only one remains, this indirection is pointless.

Prevent spurios EIO on EOF.

Notwithstanding the return value the frame should be freed if
is not going to be used.

Fix the mispresented EINVAL for EOF on partial files, among the other.

0.1 seconds at 25 fps is exactly 2.5 frames, which may be rounded either
to 2 or 3 on different platforms.

The scale filter depends on sws, resample on lavr, and movie on lavf and
lavc.

Fixes Bug 502.

They are now used for -ss/-t

It is incompatible with refcounted frames and since it's been deprecated
for a long time now, fixing it is not worth the effort.

They are not guaranteed to be aligned.
Fixes Bug 503.

Fixes memory leak in fate-redcode-demux.

Fixes Fate tests on big-endian configs.

Use bitfields in FormatEntry array to avoid wasting an int for each flag.

Every other pixel had the alpha channel taken from the wrong
row.

This fixes bug 504.

The function is only instantiated once, so there is no point
in keeping it in a template file.
