Allows to specify the action to be performed when reading the last frame
from the internal FIFO buffer. By default the last frame is written to
filter output depending on the timestamp rounding method. When using
"pass" action the last frame is passed through if input duration
has not been reached yet.
Examples using an input file with 25Hz, 1.4sec duration:
- "fps=fps=1:round=near" generates an output file of 1sec
- "fps=fps=1:round=near:eof_action=pass" generates an output file of
2sec

These changes store id3 chapter data in ID3v2ExtraMeta and introduce
ff_id3v2_parse_chapters to parse them into the format context if needed.
Encoders using ff_id3v2_read, which previously parsed chapters into the
format context automatically, were adjusted to call
ff_id3v2_parse_chapters.

Some V4L2 drivers fail to allocate buffers when sizeimage is not set
to a max value. This is indeed the case for s5p-mfc [1]
Most drivers should be able to calculate this value from the frame
dimensions and format - or at least have their own default.
However since this work around should not impact those drivers doing
the "right thing" this commit just provides such a default.
The calculations were extracted from the v4l2 driver used to develop
the ffmpeg v4l2_m2m support [2]. See venc.c and vdec.c

The string is allocated with CFStringGetCString but was being
deallocated with free(), which would intermittently result in
a segmentation fault. Use the correct function for freeing the
allocated CFString.

This FFmpeg-specific "fuzzer fix" was never perfect, but now it
stopped encoding of actual content with a big enough DTS shift.
This returns the function to its original state of results
before negative CTS offsets were added.
I remember dealing with this function before, but somehow had
forgotten about it during VDD. The test cases not tripping this
over also didn't help.
