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.

av_freep(swsContext) will leak all memory potentially

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 is consistent with how all the other options work.

CommandLineToArgvW requires windows.h, include it directly

All file names should be in UTF-8 within libavformat.

This is handled by mapping the open() function to an internal one
in os_support.h for windows.

fopen() could be overridden in the same way, but if that would be
used from ffmpeg.c, it would add a dependency on an ff prefixed
internal lavf function.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

Using a preset file caused the address of a stack variable to be stored
in opt_names/values. This change causes the strings to be dup'd then

libavcodec minor version is > 99 so when printing the library versions
the output is a little bit broken:

Because DTS values aren't passed through decoders, they tend to be
inaccurate if decoder delay doesn't match what was expected by the encoder.

In particular this improves timestamps for H.264 without num_reorder_frames
set and with -strict 1, which causes DTS to be up to 16 frames ahead of the
picture.

Note that this doesn't really improve any file with very broken PTS/DTS,
since PTS isn't much more accurate in these.
