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.

Avoids warning about discarding qualifiers in avcodec.c

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.

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.

This duplicates the function fillPlane().

Remove duplicate "inC" and "_c" functions that do the same thing;
give each function that handles data and acts as a function pointer
a "_c" suffix; remove "_c" suffix from functions that are inherently
not optimizable. Remove inline keyword from functions that are only
used through function pointers.
