All option parsing functions now match the function pointer signature through
which they are called (int f(const char *, const char *), thereby working
reliably on all platforms.
Prefix all option processing functions with opt_

This removes the default samplerate of 44100 for raw input, hence all
the FATE changes.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Make it returns the list of open inputs and outputs, so it can be
reused by applications.

Breaks API/ABI.

The picture struct is written to in the loop, so this cannot work.

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.

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.

This is required for a pending simplification.

Make ff* tools only accept opt_* functions taking two arguments.

The distinction between functions with one and two arguments is quite
pointless. Simplify parse_options() code.

It's a duplicate of AVFormatContext.nb_streams.

Grow the file and stream list in opt_input_file() instead of creating it
all at once in transcode().  This is simpler and will be useful for
following commits.

AVStream.index stores the same thing.

Currently, the url_interrupt_cb callback will abort all IO
after the first received signal. This makes the output files
from e.g. the mov muxer to be unreadable if the transcode is
aborted with ctrl+c.

After this patch, the first signal cleanly breaks out of
the transcoding loop, but won't forcibly abort all IO.
After the second signal is received, the url_interrupt_cb
callback will abort all IO.

The new function accepts a slightly more intuitive order of paramters,
and returns an error code, thus allowing applications to report a
meaningful error message.

It's badly documented and does the same thing as -flags global_header,
so it's redundant.
