This is a generic solution that will not reqiore modifications when new options are added.
This also fixes problem with current implementation when qmin or qmax=-1.
Only 8 bits was sent and read back as 255.

Fixes #1275
Fixes #1461

It has not been properly maintained for years and there is little hope
of that changing in the future.
It appears simpler to write a new replacement from scratch than
unbreaking it.

Most formats do not support negative timestamps, shift them to avoid
unexpected behaviour and a number of bad crashes.

Currently FFM files generated with one versions of ffmpeg generally
cannot be read by another.
By spliting data into chunks, more fields can saftely be appended to
chunks as well as new chunks added.

Regression since 5f847bf6.

After this commit, timestamps pushed by FFmpeg won't be relative
anymore, but absolute (based on the date/time at the beginning of the
push). This will allow seeking to work properly. Before this patch, the
seek was done, but ffm timestamps were way smallers than the absolute
requested timestamp (based on a date), so the seek was done, but to the
end of the stream (which was similar to no effect at all).

This is consistent with stdio and is what we want to do in all cases.

Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.

The condition is trivially true, but keeping the assert() is
sensible to avoid FFM_HEADER_SIZE ever getting out of sync with
the actual code.

Deprecate corresponding AVCodecContext fields.

Also remove some pointless NULL/0 assigments.

C++ code must be left as it is because named struct
initializers are not supported by C++ standard.

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).

This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.

The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).

The old functions are marked deprecated and retained for
compatibility.

It's supposed to be called only from (de)muxers.

Deprecate AVCodecContext.directpred

Deprecate AVCodecContext.partitions.

It's more readable and less prone to breakage.

AVStream is no place for it and it's unused outside of ffmpeg anyway.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
