Support Matroska native formatting.
On demuxing prepend a Frame container atom (32bit big endian encoded
frame size and 'icpf' string).
On muxing remove it.
Adds a flag context_reinit to MpegEncContext to relieable keep track
of frame parameter changes which require a context reinitialization.
This is required for broken inputs which change the frame size but
error out before the context can be reinitialized.
Thus comparsion against int64_t value will not raise warning
(from -Wextra set) about comparsion of unsigned and signed integer
commiter added () and changed the litteral to unsigned

As a sideeffect this makes the code more robust if a future change leaves
a path where it may be uninitialized otherwise.

The GRAPH_DESCRIPTION string supplied to graph2dot must include explicitly
defined inputs and outputs which are not normally part of the command line
used in a real invocation.
This clarifies that requirement, and provides an example.

This is mainly required for frame parameter changes during frame based
multithreading but single threaded usage profits too from avoiding
ff_MPV_common_end()/ff_MPV_common_init() cycles.
Filters now use null pointers to indicate having no input/output pads,
rather than empty lists of pads. We can't assume pad is non-null
anymore.

This fixes stream copy from a format that already has incompatible
codec tags set. The chained ismv muxer exports this same codec tag
list, so set it on this one as well, to allow the caller (and
lavf common code) to set them correctly.

A quite widespread pattern in the demuxer is read a 32bit unsigned
integer and then loop till this value is reached.
Checking for EOF prevents pathological situations.
