doc: Add more information in the README

And convert it to Markdown.
lavr: Update the planar check in ff_audio_convert

mxf: Add UID print helpers

And use it to print non-parsed ULs.
mxf: Add the UL for the MPEG2VideoDescriptor
mxf: Support AAC

Update mxf_set_audio_pts to use the container-provided information.

The UL is marked as "to be changed in the future", but the current
samples in the wild do use it.
Prepare for 11_beta1 Release
doc: Change wrong term to avoid confusion

A function declaration is the prototype.

proresenc: Report buffer overflow

If the allocated size, despite best efforts, is too small, exit
with the appropriate error.

proresenc: Realloc if buffer is too small

The buffer allocation may be incorrect (e.g. with an alpha plane),
and currently causes the buffer to be set to NULL by init_put_bits,
causing a crash later on.

So, detect that situation, and if detected, reallocate the buffer
and ask for a sample that shows the problem.

proresenc: Properly account for alpha plane

The packet buffer allocation considers the alpha channel as DCT-coded,
while it is actually run-coded and thus requires a larger buffer.

mov: Drop unused parameter from ff_mov_read_esds()

This is cleaner and avoids an uninitialized variable warning with MSVC.
vfwcap: Drop fallback VfW defines

The defines were added long ago when MinGW still lacked them.
vc1: Add missing parentheses to conditions in vc1_decode_b_mb_intfr()
pcm: Drop unused variable from DECODE_PLANAR macro
pcm: Drop av_unused attribute from variable that is always used
vsrc_movie: Avoid a variable indirection in movie_get_frame()

This avoids an unused variable warning with MSVC since the variable is
only used in a debug mode printf statement.
avfilter: Remove unused variable from ff_get_video_buffer()
vsrc_movie: Adjust a silly typo from b977b287f61fea48ecd6251d54a26334213b7ec6
