This is for emulating a low-resolution pixellated look,
or possibly as a performance boost on slow graphics cards.

Initially I thought that we would never need to draw an alias model that hadn't been precached when R_NewMap runs, but this assumption turned out to be incorrect. This fixes the issue where progs/bolt.mdl wasn't rendering in the Scourge Done Slick demos.

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.

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.

timerefresh command not to draw to the front buffer. also made sure
that there is an active connection when timerefresh is called.

- removed the archive and server members of cvar_t structure
which are now represented by the CVAR_ARCHIVE, CVAR_NOTIFY
and CVAR_SERVERINFO flags.
- added new Cvar_SetROM and Cvar_SetValueROM functions to
set vars marked as CVAR_ROM (read-only vars) programaticaly
- added Cvar_SetCallback() as a new function to assign (or
remove) a callback function to a cvar.
- changed Cvar_RegisterVariable() to only accept a var pointer
as in original quake
- moved notification handling from Cvar_Set() to callbacks.
- changed Cvar_Set() so that it doesn't reallocate the var's
string buffer if nothing is changed, nor does it run the
var's callback.
- changed the 'registered' and 'cmdline' cvars to be read-only
so that the users can't change it using the console. (and
with 'registered' flagged as CVAR_ROM, the 'static_registered'
thing is no longer required)
- added comment that sending cmdline upon CCREQ_RULE_INFO is
evil...
- more to follow later.

server: R_Init() isn't called for dedicated server therefore gl_subdivide_size
was used without being registered hence divisions by zero when using its value
member. Geez.. Moved its registration to Mod_Init() and we are good.

take a milliseconds argument, added implementations for unix (usleep) and
windows (Sleep).
