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

It may be a useful alternative to the existing gamma control for laptops in a bright environment, etc.
(raising contrast gives less of a gray/washed out look than raising gamma, but as a disadvantage, colours near white get clipped to white.)
It's also implemented for both GLSL and SDL gamma ramps, but only if USE_GAMMA_RAMPS is set to 1.
Since USE_GAMMA_RAMPS is 0, currently it only works with GLSL.

"The buffers should always be cleared. On much older hardware, there was a technique to get away without clearing the scene, but on even semi-recent hardware, this will actually make things slower. So always do the clear."
Plus it's nice for map development / debugging.

Fixes a obscure bug where:
- a bsp with no textures (pink checkerboard displayed)
- gamma != 1
- nothing else on screen (sbar hidden, r_drawviewmodel 0)
would result in the screen turning to noise.

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.

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.

- 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.
