Renamed for consistency. Also, since print_int() and print_str() are
already defined as macros, the long name version is preferred.

Having a string callback is much more simpler than a variable args
one for writers to deal with, especially when dealing with escaping.

This patch also introduces a local fast_asprintf() function which is
similar to av_asprintf() but avoids reallocating at each print (leading
to a performance issue).

Adds support for decoder-private options and makes setting other options
simpler.

This is required after the OPT_FUNC2 removal.

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_

Useful for mimicking the ffmpeg -i FILE syntax.

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.

Replace "codec (id=%d)" with "codec with id %d", slightly more
readable.

Provide a non-NULL AVFormatParameters structure to
av_open_input_file() in open_input_file().

This is required because otherwise av_open_input_file() will allocate
and use a new format context, discarding the options set in the
provided format context.

Replace "codec (id=%d)" with "codec with id %d", slightly more
readable.
