Log Message:
Update multimedia/{gmplayer,mencoder,mplayer,mplayer-share} to 1.2.1.

pkgsrc changes:
 o Switch all mplayer packages to use multimedia/ffmpeg2 instead of the
   version bundled with MPlayer. This will make maintainership of mplayer
   packages probably a bit easier (and it's particular relevant when dealing
   vulnerability issues). Discussed with wiz@.
 o Adjust CONFIGURE_ARGS and other part of the Makefile* to reflect the switch
   to multimedia/ffmpeg2.

Changes:
  1.2.1:
    Fixes:
    * misc GUI fixes
    * fix build regression in FreeBSD
    * fix many crashes with fuzzed files
    * fix errors for multichannels files and pulseaudio >= 6
    Other:
    * building with system FFmpeg libs is possible without a local copy of
      of private FFmpeg headers
    * docs building does not require FFmpeg anymore
    * FFmpeg updated to 2.8.5
