Previously, the pkt_size option only affected write buffering in the file
protocol. This change extends its effect to read mode as well.
On embedded systems with limited RAM, users can now reduce I/O buffer
memory by setting a smaller pkt_size.

Add a "pkt_size" AVOption to the Unix domain socket protocol. This option
allows the user to specify the maximum packet size for packet-oriented
sockets (SOCK_DGRAM and SOCK_SEQPACKET).

While we only add the flag if the linker seems to support it,
it turns out that ld.bfd had a bug where the flag is accidentally
accepted, and the flag produces an output file named
"_warn_duplicate_libraries".
The ld.bfd bug was fixed in binutils 2.36, in
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=3991c7acb29aa8d7d52150695eb3efa03a08dd50.

If 'sname:*' is set in the var_stream_map variable, use it as
the NAME attribute for subtitles. This improves the naming of
subtitle streams in HTML players, providing clearer and more
descriptive labels for users.

Split it into sections that describe in detail
* the components of the transcoding pipeline
* the main features it handles, in order of complexity
* streamcopy
* transcoding
* filtering
Replace the current confusing/misleading diagrams with new ones that
actually reflect the program components and data flow between them.
We started defauling to nasm 8 years ago.
We are still compatible with yasm 0.8.0, released in 2009. **15 years ago**.
The time has more than come to remove support for it.
Maintaining compatibility started cutting into writing new code long ago.
We still can't have 2-argument instructions, preprocessor booleans, and all
AVX2 code must still be wrapped in ifdefs. Newly added code often breaks this.
Add a mechanism to AVClass to allow objects to signal their state to
generic code. When an object flags itself with the 'initialized' state,
print an error (and fail, after the next major bump) if the caller
attempts to set non-runtime options.
Will be used to export certain information present in HEIF samples, like
rotation metadata, ICC profiles, and potentially others.

"int-list" options are a hack that provides rudimentary support for
array-type options by treating them as byte arrays (i.e.
AV_OPT_TYPE_BINARY). Since we now have proper array-type options, they
should replace "int-list" everywhere (which happens to be just
buffersink).
I plan to look after and test them for the forseeable future.
I am not a committer but do care for these muxers/demuxers.

This extends the syntax for specifying input streams in -map and complex
filtergraph labels, to allow selecting a view by view ID, index, or
position. The corresponding decoder is then set up to decode the
appropriate view and send frames for that view to the correct
filtergraph input(s).
