The celt_delay AVAudioFifo is always allocated during init, so checking
for its existence in .flush is unnecessary.

Modifying static storage must not happen because of multithreading
(except initialization of course), so add const to the pointed-to type
for pointers that point to static storage.

These two are always called directly after each other (with the
exception of the calls in mpeg_decode_init() where some irrelevant
modifications of the avctx (which could just as well be done before
ff_mpv_decode_defaults(), because it doesn't have a pointer to the
AVCodecContext at all and therefore can't see these modifications at
all) are performed in between), so merge ff_mpv_decode_defaults() in
ff_mpv_decode_init().

This automatically makes the eamad, eatqi, ipu and mdec decoders
init-threadsafe; in addition to the actual mpeg[12]video decoders,
of course.

ff_mpeg12_init_vlcs() currently initializes index_run, max_level and
max_run of ff_rl_mpeg1/2; yet the only user of these fields is the
MPEG-1/2 encoder which already initializes these tables on its own.
So remove the initializations in ff_mpeg12_init_vlcs(); this also
simplifies making ff_mpeg12_init_vlcs() thread-safe.

ff_rl_free() was added in 324e50ee95929a9491b855c5e15451145bd5d1ec,
but never used; nonstatic storage was not used long before that.

This was introduced in version 4.6. And may not exist all without an
optional package. So to prevent a hard dependency on needing the Linux
kernel headers to compile, make this optional.
Also ignore the status of the ioctl, since it may fail on older kernels
which don't support it. It's okay to ignore as its not fatal and any
serious errors will be caught later by the mmap call.
'void *' is too flexible, since we can derive info from
AVFilterContext*, so we just unify the interface with this data
structure.

This can be used to receive the raw mpegts stream from a SAT>IP
server, by letting avformat handle the RTSP/RTP/UDP negotiation
and setup, but then simply passing the MP2T stream through
instead of demuxing it further.
For example, this command would demux/remux the mpegts stream:
SATIP_URL='satip://192.168.1.99:554/?src=1&freq=12188&pol=h&ro=0.35&msys=dvbs&mtype=qpsk&plts=off&sr=27500&fec=34&pids=0,17,18,167,136,47,71'
ffmpeg -i $SATIP_URL -map 0 -c copy -f mpegts -y remux.ts
Whereas this command will simply write out the raw stream, with
the original PAT/PMT/PIDs intact:
ffmpeg -rtsp_flags satip_raw -i $SATIP_URL -map 0 -c copy -f data -y raw.ts

When targeting a recent enough macOS/iOS version that has clock_gettime
it won't be a weak symbol, in which case clang warns for this check
as it's always true:
warning: address of function 'clock_gettime' will always
evaluate to 'true'
This warning is silenced by using the address-of operator to make
the intent explicit.
