output-example.c (and renamed to muxing-example.c) has been moved to
doc/examples.

The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.

Parts are inspired from the 8-bit H.264 predict code in Libav.
Other parts ported from x264 with relicensing permission from author.

Setting a standard is meaningful only for analog capture devices.

Avoids warning about discarding qualifiers in avcodec.c

It is only used on the host and may not compile on the target.

The filename is unnecessary and brittle across file renames.

It's simpler and less error-prone.

Fixes some memleaks along the way.

Avoid to add frames to the vsrc_buffer in the case ist->pts <
start_time, as these frames are unused (and never released). In
particular this condition is verified with commands of the kind:
ffmpeg -i INPUT -ss TIME OUTPUT

Also allow a minor simplification.

Useful for mimicking the ffmpeg -i FILE syntax.

This fixes the build with hardcoded tables enabled.

The -i INPUT option can be implemented more cleanly by using a
function option, which can easily be done now that the
parse_arg_function passed to parse_options has a standard signature.

This is required for a pending simplification.

This allows a more efficient use of the commandline.

Helps debugging.
