Integer overflow in the Q16 framerate calculation was sending
invalid values to the OMX encoder.
On the RPI4, this manifested as bitrate controls being ignored
on video streams with 60000/1001 framerates. Video streams with
30000/1001 framerates were not affected.

After a1b4f120c0 the teletext PTS values were set
to AV_NOPTS_VALUE if the stream of the PCR pid was discarded.
What actually matters is that if we parse the PCR of the PCR PID or not, so
let's use the cached discard value of the actual PCR PID instead of the stream
discard value, which may be different.
Also fixes ticket #7567, which was caused by the fact that teletext PTS values
were not touched if the PCR pid was discarded even before
a1b4f120c0.

See https://trac.ffmpeg.org/ticket/7687
If an encoded frame is returned split over two or more
IL buffers due to the size, then there is a race between
whether get_buffer will fail, return NULL, and a truncated
frame is passed on, or IL will return the remaining part
of the encoded frame.
If get_buffer returns NULL, part of the frame is left behind
in the codec, and will be collected on the next call. That
then leaves a frame stuck in the codec. Repeat enough times
and the codec FIFO is full, and the pipeline stalls.
A performance improvement in the Raspberry Pi firmware means
that the timing has changed, and now frequently drops into the
case where get_buffer returns NULL.
Add code such that should a buffer be received without
OMX_BUFFERFLAG_ENDOFFRAME that get_buffer is called with wait
set, so we wait for the remainder of the frame.
This code has been made conditional on the Pi build in case
other IL implementations don't handle ENDOFFRAME correctly.

(cherry picked from commit 3d857f219e)
matroska_reset_status (a function that is used during seeking (among
other things)) used an int for the return value of avio_seek which
returns an int64_t. Checking the return value then indicated an error
even though the seek was successfull for targets in the range of
2GB-4GB, 6GB-8GB, ... This error implied that the status hasn't been
reset and in particular, the old level was still considered to be in
force, so that ebml_parse returned errors because the newly parsed
elements were of course not contained in the previously active and still
wrongly considered active master element any more.

The initialization of the uint32_t plane32_lut matrix uses left shifts
of the form 1 << plane; plane can be as big as 31 which means that this
is undefined behaviour as 1 will be simply an int. So make it unsigned
