Does not make a difference in this case since sizeof(uint8_t*) ==
sizeof(uint8_t**). Fixes CID703814.

It has not worked for anything other than fringe codecs (asv1/2, mdec,
mjpeg[b]) since about 2003 and nobody ever noticed or complained. This
sufficiently proves that there are no users of this option who have a
clue of what they are doing, so it is completely useless.

Fixes CID732166.

Fixes CID732273.

Fixes CID732272.

Fixes CID732271.

Prevents writes to freed memory and the leak of the old extended data.
Fixes CID732303.

Make just a single reallocation per call instead of one reallocation
per copied chapters. This fixes possible memory leaks on realloc
failures. Also correct the allocation since it needs multiples of
sizeof(AVChapter*) and not sizeof(AVChapter).

Fixes CID700633 and CID700719.

Prevents memory leak and possible access to freed memory.
Fixes CID605744.

Prevents CID602000.

The test programs use internal symbols so cannot be linked against the
shared libs.  Linking against both shared and static is pointless and
might do something strange depending on the linker.  This changes the
dependencies so the test programs are linked only against the static
library for the component they belong to.

This was done to work around toolchain bugs that have long been fixed.

Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.

The vec_splat() intrinsic requires a constant argument for the
element number, and the code relies on the compiler unrolling
the loop to provide this.  Manually unrolling the loop avoids
this reliance and works with all compilers.
