9ea6d2149e avcodec/decode: add a flags parameter to ff_reget_buffer() 
Some decoders may not need a writable buffer in some specific cases, but only
a reference to the existing buffer with updated frame properties instead, for
the purpose of returning duplicate frames. For this, the
FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential
allocations and buffer copies when they are not needed.

When compiling natively on an RPI where libomxil-bellagio-dev
was also installed, `check_headers OMX_Core.h` succeeded and
the -isystem compiler flag was never added to the build.

For non-native builds, the error message now mentions the
raspberrypi/firmware repository where the RPI specific
headers are available.

ef43a4d6b3 avformat: Add ZeroMQ as a protocol 
When ffmpeg was streaming, multiple clients were only supported by using a
multicast destination address. An alternative was to stream to a server which
re-distributes the content. This commit adds ZeroMQ as a protocol, which allows
multiple clients to connect to a single ffmpeg instance.

b022d9ba28 avcodec/omx: fix xFramerate calculation 
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.

f4eb7d84a7 avformat/mpegtsenc: fix flushing of audio packets 
7d097a0fc5 had the same purpose as
3700f655c5 but the former is much simpler, so
let's remove the latter.

Unfortunately both checks were wrong, because in order to make sure DTS > PCR
we have to give us some headroom, so instead of using a dts_difference <
max_delay check let's use a dts_difference < max_delay/2 check.

Fixes DTS < PCR errors with this command line:
