R_DrawTextureChains_Multitexture: revert to the way it was before VBO support was added.
gl_texmgr: expose GL_SelectTexture. make the implementation less convoluted and support 3 TMUs.
gl_vidsdl: check GL_MAX_TEXTURE_UNITS
r_brush: only create VBOs if 3 TMUs available

This seems to help fps a fair bit on maps with a lot of world polys like jam2_tronyn. Tried on a few computers with intel and nvidia gpus, windows, mac os, linux, and there's always at least some fps improvement. Best case was 70fps -> 96fps on jam2_tronyn, on OS X + nvidia 650gt.
Interested to hear how this works for amd gpu's, just do a timedemo with and without "-novbo".
Only downside is I had to disable the fast path in Vid_Toggle_f() because at least with SDL1, the vbo no longer works after a toggle. So as a result, fullscreen toggles with alt-enter are slightly slower.

To make this work with the drawing order we use in gl_rmain (world excluding water, opaque ents, world water, transparent ents), I made each texture_t have two texture chains, one for world and one for bmodels. This way they can be cleared during entity drawing without having to regenerate the world ones.
Other than this the changes are mostly minor adjustments to the R_DrawTextureChains_* functions so they can work for things other than the world.

Not implemented for world polys (afaik it's useless for world polys) but could be added if needed.

Can speed up map loading by multiple seconds on levels with a lot of lightmaps, at a cost of using slightly more lightmaps (about 5% more).

performance boost on some systems. add GL_BGRA as an option, thanks
to Kristian Duske. the format is hardcoded as GL_RGBA for now,
need a way to make it configurable later.

of using size_t instead of it. include stdint.h in q_stdinc.h for it.
for Visual Studio earlier than version 2010, use the header provided by
the msinttypes project.
