Both GCC and Clang create code that inlines the loops in
next_input() and next_output() at high optimization
levels (presumably when there are not too many devices)
and this code leads to the creation of .got entries:
e7: 48 3b 3d 00 00 00 00 cmp 0x0(%rip),%rdi # ee <av_input_video_device_next+0xe>
ea: R_X86_64_REX_GOTPCRELX ff_alsa_demuxer-0x4

f0: 48 3b 3d 00 00 00 00 cmp 0x0(%rip),%rdi # f7 <av_input_video_device_next+0x17>
f3: R_X86_64_REX_GOTPCRELX ff_fbdev_demuxer-0x4
f7: 74 41 je 13a <av_input_video_device_next+0x5a>
These relocations can't be fixed up lateron when it is known
that the symbols exist in the same DSO.
This commit therefore marks these symbols as hidden, leading
to code like this:
f7: 48 8d 05 00 00 00 00 lea 0x0(%rip),%rax # fe <av_input_video_device_next+0xe>
fa: R_X86_64_PC32 ff_alsa_demuxer-0x4

10d: 74 50 je 15f <av_input_video_device_next+0x6f>

that tries to read the addresses from the .got given that the
addresses can be read directly from indev_list/outdev_list.)

This commit does for AVInputFormat what commit
59c9dc82f450638a3068deeb1db5c56f6d155752 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.
This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).
This is possible since 50f34172e0cca2cabc5836308ec66dbf93f5f2a3
(which removed the last usage of an internal field of AVInputFormat
in fftools).
(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

Makes it robust against adding fields before it, which will be useful in
following commits.
Majority of the patch generated by the following Coccinelle script:
@@
typedef AVOption;
identifier arr_name;
initializer list il;
initializer list[8] il1;
expression tail;
@@
AVOption arr_name[] = { il, { il1,
- tail
+ .unit = tail
}, ... };
with some manual changes, as the script:
* has trouble with options defined inside macros
* sometimes does not handle options under an #else branch
* sometimes swallows whitespace
This can be achieved by using AV_OPT_TYPE_FLAGS instead of
AV_OPT_TYPE_STRING. It also avoids strcmp() when accessing
the option.

It implements BSD-specific support for very old analog capture cards,
which are highly unlikely to be useful today. After being added in 2005,
there were never any commits to it beyond compilation fixes and generic
maintenance. There have also been zero trac tickets for this device, and
the only related web search result I found concludes that it does not
work.
The code also does some unacceptable things, like messing with signal
handlers and storing its state in global variables.
Some callers assume that item_name is always set, so this may be
considered an API break.
This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;

Converting from an integer to HWND (which is a pointer) requires
an explicit cast, otherwise Clang errors out like this:
src/libavdevice/gdigrab.c:280:14: error: incompatible integer to pointer conversion assigning to 'HWND' (aka 'struct HWND__ *') from 'long' [-Wint-conversion]
280 | hwnd = strtol(name, &p, 0);
| ^ ~~~~~~~~~~~~~~~~~~~
(With GCC and MSVC, this was a mere warning, but with recent Clang,
this is an error.)
After adding a cast, all compilers also warn something like this:
src/libavdevice/gdigrab.c:280:16: warning: cast to 'HWND' (aka 'struct HWND__ *') from smaller integer type 'long' [-Wint-to-pointer-cast]
280 | hwnd = (HWND) strtol(name, &p, 0);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
On Windows, long types are 32 bit, so to get a usable pointer, we
need to use long long. And interpret it as unsigned long long
while at it - i.e. using strtoull.
Finally, right above it, the code triggered the following warning:
src/libavdevice/gdigrab.c:278:15: warning: mixing declarations and code is incompatible with standards before C99 [-Wdeclaration-after-statement]
278 | char *p;

Deprecate AVStream.side_data and its helpers in favor of the AVStream's
codecpar.coded_side_data.
This will considerably simplify the propagation of global side data to decoders
and from encoders. Instead of having to do it inside packets, it will be
available during init().
Global and frame specific side data will therefore be distinct.

It is of no value to the user, because every muxer can always
be flushed with a NULL packet. As its documentation shows
("If not set, the muxer will not receive a NULL packet in
the write_packet function") it is actually an internal flag
that has been publically exposed because there was no internal
flags field for output formats for a long time. But now there is
and so use it by replacing the public flag with a private one.

lots of user have uint8_t* const * and therefore either
cast (the majority) or copy the array of pointers.
