46fb395952 libavformat/concatdec: remove support for unsafe=-1 
It only makes sense as the default value,
but it is not the default since 689211d5727231c3fe92762d224dbadebdbf4e30.

e88db774d8 avfilter/avfilter: Deprecate avfilter_pad_count() 
It is unnecessary as the number of static inputs and outputs can now
be directly read via AVFilter.nb_(in|out)puts.

7c5f998196 avfilter/avfilter: Add avfilter_filter_pad_count() 
It is intended as replacement for avfilter_pad_count(). In contrast to
the latter, it avoids a loop.

8c53b14599 avutil/opt: Document actual behaviour of av_opt_copy a bit more 
In particular, document that av_opt_copy() always disentangles
allocated options even on error; this guarantee is needed to e.g.
properly free duplicated thread contexts in libavcodec on error.

imgutils: expose av_image_copy_plane_uc_from() 
The reason why the generic av_image_copy_uc_from() doesn't really
fit in the case for Vulkan is because some planes may be copied via
other methods (such as mapping GPU memory), and if they don't satisfy
the strict alignment requirements, a gpu image->gpu buffer->cpu ram
copy is performed.

We need this for hwcontext_vulkan, and I think this will also be
useful to API users like libplacebo who would rather not write
a custom SIMD memcpy.

2dd8acbe80 avutil/common, macros: Move several macros from common.h to macros.h 
common.h currently contains several things: Math macros, UTF-8 macros,
other fundamental macros; furthermore it also contains miscellaneous
math functions and it (directly and indirectly) includes lots of other
headers.

This commit moves the "other fundamental macros" to macros.h which is
a more fitting place.

b7ba472f43 avfilter/fps: remove unconventional acronyms 
In dd770883e9, support for expressions was added. Among the constants
added were labels of qnstc, qpal, sntsc & spal.

These were added in ba2a8cb40b to represent parameter permutations where
only the resolution is different. They don't have any usage currency and
don't represent any industry standards or convention in terms of framerate.
