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)’

Add a dummy option -i to ffplay so that it is easy to switch between ffmpeg -i "file" and ffplay -i "file".

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.
