Add comments to describe the sources of the constraint values expressed here,
and add some more related values which will be used in following patches.
Fix the incorrect values for SPS and PPS count (they are not the same as those
used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere.

This has been unused for a long time, and the original purpose has been
replaced by the per-stream hwaccel_flags.

Should prevent some options from being added to cflags when they
don't exist and the compiler only warns about it.

The library has several dependencies that vary between systems.
Their pkg-config properly lists them all.

Two of them are missing it in their pkg-config file, so adding it
here is a workaround until said pkg-config files are fixed.

The public functions av_alloc_vdpaucontext() and
av_vdpau_alloc_context() are allocating AVVDPAUContext
structure that is supposed to be placed in avctx->hwaccel_context.
However the rest of libavcodec/vdpau.c uses avctx->hwaccel_context
as struct VDPAUHWContext, that is bigger and does contain
AVVDPAUContext as first member.
The usage includes write to the new variables in the bigger stuct,
without checking for block size.
Fix by always allocating the bigger structure.
