Used vlc_fourcc_t.
Protected a macro.
Used var_CreateGetNonEmptyString where needed.
Cosmetics.

 The rawvideo stream may not be CFR but has a timestamp for every frame.
 Anyway I prefer that we try to display the stream even with small glitches
than rejecting it.

demux:
 - Use accurate timestamps (date_t)
 - Signal frame rate in fmt_out
 - Fix aspect ratio for YUV4MPEG2
 - Reoganise input options to allow sensible overrides
   Ie: extension gussing < yuv4mpeg < cmdline

codec/packetizer:
 - Fix incorrect assumption of 25 fps video
 - Use accurate timestamps (date_t)
 - Copy input format as output format (to preserve frame rate)
 - Set progressive flag per picture

TODO:
 - Have module option for interlaced
 - Detect interlaced in demux for YUV4MPEG2
 - Have codec read set the interlaced flags in the video
 All seems rather tricky for the moment (well, YUV4MPEG2 bit does,
 since the demuxer strips the headers that reveal the interlace
 mode).

 Do not use vout_Request in aout_filter_t anymore but aout_filter_RequestVout.
 They have the same semantic but it will allows to control every vout creation
from aout.

NB, this highlights some reference counting strangeness.

Should fix some aspect ratio related pain, amongst others.
