6ca43a9675 avdevice/lavfi: output wrapped AVFrames
This avoids an extra copy of potentially quite big video frames.
Instead of copying the entire frames data into a rawvideo packet it
packs the frame into a wrapped avframe packet and passes it through
as-is.
Unfortunately, wrapped avframes are set up to be video frames, so the
audio frames continue to be copied.

Additionally, this enabled passing through video frames that previously
were impossible to process, like hardware frames or other special
formats that couldn't be packed into a rawvideo packet.

64f04df379 avdevice/avdevice: fix return value of avdevice_list_devices()
According to API docs avdevice_list_devices(), avdevice_list_input_sources()
and avdevice_list_input_sinks() should return the number of autodetected
devices on success. This is redundant with AVDeviceInfoList->nb_devices so it
was not noticed earlier that none of the underlying device list functions work
like that.

Let's fix it in generic code to make it in line with the API docs.

Fixes ticket #9820.

b67ca8a7a5 avdevice/pulse_audio_dec: reduce default fragment size
Reduces default fragment size from the pulse audio default of 2 sec to 50 ms.
This also has an effect on the size of the returned frames, which will be
around 50 ms as well, making timestamps more accurate.

This should fix the regression in ticket #9776.

Pulseaudio timestamps for monitor sources are still pretty inaccurate for me,
but I don't see how else should we query latencies from the library.

iec61883_parse_queue_hdv() is only called when the mpegts-demuxer
is available and can be optimized away when not. Yet this
optimization is not a given and it fails with e.g. GCC 11 when
using -O0 in which case one will get a compilation error
because the call to the unavailable avpriv_mpegts_parse_packet()
is not optimized away. Therefore #if the offending code away
in this case.

d61240f8c9 avcodec/packet_internal: Add proper PacketList struct
Up until now, we had a PacketList structure which is actually
a PacketListEntry; a proper PacketList did not exist
and all the related functions just passed pointers to pointers
to the head and tail elements around. All these pointers were
actually consecutive elements of their containing structs,
i.e. the users already treated them as if they were a struct.

So add a proper PacketList struct and rename the current PacketList
to PacketListEntry; also make the functions use this structure
instead of the pair of pointers.

d82c91ba2f configure, avcodec/Makefile: Add new mpeg4audio CONFIG_EXTRA group
This group is mainly for the users of *_mpeg4audio_get_config2();
it is not for those who only use avpriv_mpeg4audio_sample_rates.
This is in preparation for splitting the latter into a file of its own;
if there were no CONFIG_EXTRA group for *_mpeg4audio_get_config2()
users, one would have to add a dependency to the new file for all
these users on top of the existing dependency on mpeg4audio.o.

Adding a new CONFIG_EXTRA group only takes effect after a reconfigure;
so in order to force a reconfigure some unnecessary headers from
libavdevice/alldevices.c have been removed.

3d53cefb49 avcodec/raw: Reduce number of avpriv symbols
libavcodec currently exports four avpriv symbols that deal with
PixelFormatTags: avpriv_get_raw_pix_fmt_tags, avpriv_find_pix_fmt,
avpriv_pix_fmt_bps_avi and avpriv_pix_fmt_bps_mov. The latter two are
lists of PixelFormatTags, the former returns such a list and the second
searches a list for a pixel format that matches a given fourcc; only
one of the aforementioned three lists is ever searched.

Yet for avpriv_pix_fmt_bps_avi, avpriv_pix_fmt_bps_mov and
avpriv_find_pix_fmt the overhead of exporting these functions actually
exceeds the size of said objects (at least for ELF; the following numbers
are for x64 Ubuntu 20.10):
The code size of avpriv_find_pix_fmt is small (GCC 10.2 37B, Clang 11 41B),
yet exporting it adds a 20B string for the name alone to the exporting
as well as to each importing library; there is more: Four bytes in the
exporting libraries .gnu.hash; two bytes each for the exporting as well
as each importing libraries .gnu.version; 24B in the exporting as well
as each importing libraries .dynsym; 16B+24B for an entry in .plt as
well as the accompanying relocation entry in .rela.plt for each
importing library.

The overhead for the lists is similar: The strings are 23B and the
.plt+.rela.plt pair is replaced by 8B+24B for an entry in .got and
a relocation entry in .rela.dyn. These lists have a size of 80 resp.
72 bytes.

Yet for ff_raw_pix_fmt_tags, exporting it is advantageous compared to
duplicating it into libavformat and potentially libavdevice. Therefore
this commit replaces all library uses of the four symbols with a single
function that is exported for shared builds. It has an enum parameter
to choose the desired list besides the parameter for the fourcc. New
lists can be supported with new enum values.

Unfortunately, avpriv_get_raw_pix_fmt_tags could not be removed, as the
fourcc2pixfmt tool uses the table of raw pix fmts. No other user of this
function remains.
