Also document it and replace undocumented and inconsistent
'-sample_fmt list' syntax with -sample_fmts.

This allows options like -target, which are just shortcuts for other
options, to work without dummy function for all options they invoke.

This is the first step to removing the globals plague from avtools.

This will be useful in the following commit.

Allows cmdutils to call each tool's own cleanup function.

Avoid brittle and obfuscating reference to a global.

Split them when codec id is known.

It stores options in a dictionary to be passed to new open calls.

It will replace opt_default once all the pieces are in place.

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.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

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)’

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.
