0066e79c9e avcodec/libopenh264dec: Increase array sizes, fix stack-buffer overread 
av_image_copy() expects an array of four pointers and linesizes
according to its declaration; it currently only pointers that are
actually in use (depending upon the pixel format), but this might
change at any time. It has already happened for the linesizes in
d7bc52bf45 and so increasing their
array fixes a stack-buffer overread.

This fixes a -Wstringop-overflow= and -Wstringop-overread warning
from GCC 11.2.

d1f7a44e89 avcodec/libkvazaar: Increase array size 
av_image_copy() expects an array of four pointers according to its
declaration; although it currently only touches pointers that
are actually in use (depending upon the pixel format) this might
change at any time (as has already happened for the linesizes
in d7bc52bf45).

This fixes a -Wstringop-overflow= warning with GCC 11.2.

717c7f4ae9 avcodec/Makefile: Only compile nvenc.o if needed 
This fixes compilation errors in case nvenc is enabled
(e.g. autodected) with both nvenc-based encoders disabled
because nvenc uses ff_alloc_a53_sei(), yet only the nvenc-based
encoders require atsc_a53.
(This error does not manifest itself in case of static linking
(nothing pulls in nvenc.o), but it exists with shared builds.)
