avconv: remove presets.

Browse Source 
Nothing except x264 uses them and native x264 presets should be used
with private options.

@section Preset files
A preset file contains a sequence of @var{option}=@var{value} pairs,
one for each line, specifying a sequence of options which would be
awkward to specify on the command line. Lines starting with the hash
('#') character are ignored and are used to provide comments. Check
the @file{ffpresets} directory in the Libav source tree for examples.
Preset files are specified with the @code{vpre}, @code{apre},
@code{spre}, and @code{fpre} options. The @code{fpre} option takes the
filename of the preset instead of a preset name as input and can be
used for any kind of codec. For the @code{vpre}, @code{apre}, and
@code{spre} options, the options specified in a preset file are
applied to the currently selected codec of the same type as the preset
option.
The argument passed to the @code{vpre}, @code{apre}, and @code{spre}
preset options identifies the preset file to use according to the
following rules:
First avconv searches for a file named @var{arg}.ffpreset in the
directories @file{$av_DATADIR} (if set), and @file{$HOME/.avconv}, and in
the datadir defined at configuration time (usually @file{PREFIX/share/avconv})
in that order. For example, if the argument is @code{libx264-max}, it will
search for the file @file{libx264-max.ffpreset}.
If no such file is found, then avconv will search for a file named
@var{codec_name}-@var{arg}.ffpreset in the above-mentioned
directories, where @var{codec_name} is the name of the codec to which
the preset file options will be applied. For example, if you select
the video codec with @code{-vcodec libx264} and use @code{-vpre max},
then it will search for the file @file{libx264-max.ffpreset}.
