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_
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.
On Windows/MinGW the SDL cflags re-define the main() function, which
results in a linking error if the define is not undeffed.
Since the addition of the SDL output device, SDL cflags are used also
for compiling ffmpeg and ffprobe, so we need to move this trick from
ffplay.c to a common header.
Fix trac issue #256.
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.

inttypes.h is not necessary, just stdint.h is enough.
Unconditionally #include avfilter.h in cmdutils.h. It is an installed
header with no non-standard external dependencies, so it is safe.
The function was only used in opt_sample_fmt() for listing the sample
formats. Move list_fmts() functionality directly into
opt_sample_fmt().
Also fix the warning:
ffmpeg.c: In function ‘opt_audio_sample_fmt’:
ffmpeg.c:2877: warning: passing argument 1 of ‘list_fmts’ from incompatible pointer type
cmdutils.h:163: note: expected ‘void (*)(char *, int, int)’ but argument is of type ‘char * (*)(char *, int, enum AVSampleFormat)’

avformat_opts->key.

This option limits the CPU time used by ffmpeg to the number of seconds
specified. After this time, the OS sends a SIGXCPU signal, which we
handle and attempt to exit cleanly. If the process is stuck, the OS
will deliver a SIGKILL one second later, forcibly terminating the
process.
This functionality is useful in automated setups where a runaway ffmpeg
process would otherwise go undetected.

filters.
Currently filters are not registered, so the option will show none.
