4 buffers were: mod_novis, decompressed, checkpvs, and fatpvs.
Also fix fatbytes calculation in SV_FatPVS to match the other PVS
buffers, was (numleafs+31)>>3, changed to (numleafs+7)>>3.
I am assuming the previous was a bug/typo.

new worldspawn keys: _wateralpha, _lavaalpha, _slimealpha, _telealpha, _skyfog (unique to Quakespasm)
The lava/slime/telealpha cvars are non-archived, and default to 0, which means to use the value of r_wateralpha, so they have no effect by default.
The worldspawn keys allow custom maps to set these values in a way that only applies while the map is loaded, and doesn't change the cvar value. (similar to the behaviour of the "fog" worldspawn key.) They are accepted with or without the underscore, like "fog".

In GL_MakeAliasModelDisplayLists, after saving the standerd triangle strips and fans onto the hunk, if the system is GL2 capable, we also save a second version of the mdl on the hunk designed to be loaded into a VBO (GL_MakeAliasModelDisplayLists_VBO). In R_NewMap, and on video mode changes, we call GLMesh_LoadVertexBuffers which loops over all precached mdl's and loads the data into a pair of VBO's (vertices and vertex indices).
Finally, in R_DrawAliasModel, assuming no rendering options are disabling the fast-path (r_drawflat 1, r_lightmap 1, or r_fullbright 1 would disable it), we call GL_DrawAliasFrame_GLSL, which sets up all of the bindings and draws the (possibly lerped) mdl in one glDrawElements call.
Special thanks to MH for some of the code from RMQEngine and the general concept.

It was possible, but unlikely, to see artifacts from the previous code in some circumstances, e.g. "host_maxfps 10" and spin around quickly near a flashing light e1m1, you may see a surface drawn with an out-of-date lightmap for one frame.

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.

It caused a dramatic slowdown on my machine on windows (50% slower)

The glBegin(GL_POLYGON), for() loop with GL_MTexCoord2fFunc()/glVertex3fv() calls, and glEnd () per polygon is replaced by a memcpy() and a glDrawArrays() call per poly.
My guess is this only saves function call overhead, but it gives a decent ~20% speedup (36 -> 42fps) on my machine on orl’s map.
Note: glDrawArrays() is in OpenGL 1.1, but the glClientActiveTextureARB function is part of the GL_ARB_multitexture extension but not GL_SGIS_multitexture. Instead of splitting into two code paths, I just dropped support for GL_SGIS_multitexture.

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.

file cannot be opened for the timedemo command. for playdemo, verify
that the forcetrack '\n' byte appears among the very first 12 bytes
of the file.

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.
