This is changing more then I wanted to at once, however. The major change is that we no longer require libGL to even exist on the system at compile time for the GL targets, we dynamicly link to the libGL of choice at run time. (This probably breaks most non-linux systems, and all GL targets except -glx, some fixup will be needed.) (This also kills glquake, dead dead DEAD! GONE FOREVER! WHEE!) Some gl_draw cleanup. Commented out equake alias model occlusion test stuff, very experimental. Added the .lo and .la patterns to the .gitignore files. Some minor sbar cleanup. (We don't use the disc in use symbol for anything.)

#include "QF/qtypes.h"
[gl] Use glGenTextures to allocate texture numbers While the scheme of using our own allocated did work just fine, fisheye rendering uses glGenTextures which caused a texture id clash and thus invalid operations (the cube map texture happened to be the same as the console background texture). Sure, I could have just "fixed" the fisheye init code, but this brings gl closer in line with glsl (which makes extensive use of glGenTextures and glDeleteTextures). This doesn't fix any texture leaks gl has (plenty, I imagine), but it's a step in the right direction.

Clean up global symbols for the gl renderer. Where possible, symbols have been made static, prefixed with gl_/GL_ or moved into the code shared by all renderers. This will make doing plugins easier but done now for link testing.
