This was part of a ghastly hack that is long since gone.

A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

Fixes bogus uninitialized value compiler and coverity warnings.

The existing code is not in the right place and it should cover both
interlaced frame and field pictures.

This is required due to the way VC-1 handles chroma pull-back which may end
up causing negative chroma MV for zero luma MV. Edge emulation needs to be
invoked in such cases.

This only affects vertical component of chroma motion vector.

Interlaced field pictures can have one or two reference pictures, signaled
by NUMREF syntax element. For single reference pictures, reference picture
is determined by REFFIELD syntax element.

GCC cannot proof that c->mc_frame_counter is always >- 0, changing the

The error codes differ between systems so printing the value makes

This makes sure proper linker arguments are used for the tools and
test programs when shared libraries are enabled.  The tools are
linked using the usual -l flag while for test programs the full
name of the static library is used.

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.

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.
