libvo, libao: remove useless video and audio output drivers

Some of these have only limited use, and some of these have no use at
all. Remove them. They make maintainance harder and nobody needs them.
It's possible that many of the removed drivers were very useful a dozen
of years ago, but now it's 2012.

Note that some of these could be added back, in case they were more
useful than I thought. But right now, they are just a burden.

Reason for removal for each module:
    vo_3dfx, vo_dfbmga, vo_dxr3, vo_ivtv, vo_mga, vo_s3fb,
    vo_tdfxfb, vo_xmga, vo_tdfx_vid:
        All of these are for very specific and outdated hardware. Some
        of them require non-standard kernel drivers or do direct HW
        access.
    vo_dga: the most crappy and ancient way to get fast output on X.
    vo_aa: there's vo_caca for the same purpose.
    vo_ggi: this never lived, and is entirely useless.
    vo_mpegpes: for DVB cards, I can't test this and it's crappy.
    vo_fbdev, vo_fbdev2: there's vo_directfb2
    vo_bl: what is this even? But it's neither important, nor alive.
    vo_svga, vo_vesa: you want to use this? You can't be serious.
    vo_wii: I can't test this, and who the hell uses this?
    vo_xvr100: some Sun thing.
    vo_xover: only useful in connection with xvr100.
    ao_nas: still alive, but I doubt it has any meaning today.
    ao_sun: Sun.
    ao_win32: use ao_dsound or ao_portaudio instead.
    ao_ivtv: removed along vo_ivtv.

Also get rid of anything SDL related. SDL 1.x is total crap for video
output, and will be replaced with SDL 2.x soon (perhaps), so if you
want to use SDL, write output drivers for SDL 2.x.

Additionally, I accidentally damaged Sun support, which made me
completely remove Sun/Solaris support. Nobody cares about this anyway.

Some left overs from previous commits removing modules were cleaned up.

-Wrangings:
- -  1bpp doesn't work right for me with '-double' and svgalib 1.4.3,
-    but works OK with svgalib 1.9.17
- -  The HW acceleration is not tested - svgalibs supports few chipsets,
-    and i don't have any of them. If it works for you then let me know.
-    I will remove this warning after confirm its status.
- -  retrace sync works only in doublebuffer mode.
- -  the retrace sync may slow down decoding a lot - mplayer is blocked while
-    waiting for retrace
- -  denoise3d fails to find common colorspace, use -vf denoise3d,scale
-
-TODO:
- - let choose_best_mode take aspect into account
- - set palette from mpi->palette or mpi->plane[1]
- - make faster OSD black bars clear - need some OSD changes
- - Make nicer CONFIG parsing
- - change video mode logical width to match img->stride[0] - for HW only
