[sldev] Reimplementing video capture using the glc capture library

[Khyota]

Ok its quite unfortunate that SL lost the movie maker function, and
that it never ran on linux, LOL. glc is an OpenGL and ALSA capture
library. The glc-capture program can record just like fraps does and
is the best thing to use for capture on liunx.

glc-caputure has support for recording multiple sound streams
seperatly to the .glc container, but it does not seem to work with SL,
its all mixed and voice doesnt get recorded. Ive talked with the
developer in IRC and he says it would probably be possible if glc was
integrated. Capture Music, Media, Voice, Sounds, Ambient, and UI
unmixed. Kinda the main reason i think it would be of benefit, other
then some convenience. Im wondering if there are any Macinimators and
coders that would want capture built into the viewer again.
