Eric Wasylishen 429b29a669 Sky_NewMap: avoid stack buffer underflow on the "remove trailing spaces"
line that happened if a map had an empty string worldspawn key,
detected by ASan on macOS with demo_map.bsp from SlayerTest.

Also prevent the strcpy's from overflowing the buffers in case of long
keys.

Eric Wasylishen 0a681bd7cd new r_scale cvar, for rendering the 3D view at 1/2, 1/3, or 1/4 res.
This is for emulating a low-resolution pixellated look,
or possibly as a performance boost on slow graphics cards.

Eric Wasylishen e007116a5d Alias model VBO renderer: restructure so each model is stored in a separate VBO and load them in Mod_LoadAliasModel, rather than R_NewMap.
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.

Steven b2465a4c82 r_pos cvar: Dynamic position info, aka r_speeds + viewpos.

Eric Wasylishen 01faf4e5b6 new cvars: r_lavaalpha, r_slimealpha, r_telealpha for fine-tuning specific liquid opacities (from DirectQ, RMQEngine)
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".

Eric Wasylishen 112c8b68b8 Alias model rendering fast-path using OpenGL 2.
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.

Eric Wasylishen e0680cb6d3 Load world and brush models into a VBO, and draw it in batches in R_DrawTextureChains_Multitexture. Uses the same immediate mode code as before if VBOs are not available, or if "-novbo" used at the command line. I only touched R_DrawTextureChains_Multitexture because it's usually the main bottleneck aside from alias model rendering.
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.

Ozkan Sezer c66cadc05a removed the envmap command which drew to front buffer. adjusted the
timerefresh command not to draw to the front buffer. also made sure
that there is an active connection when timerefresh is called.

Ozkan Sezer 1928f2e1b8 * first shot at cvar flag system and cvar layer clean-ups :
- 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.

Ozkan Sezer 5f0d6b07d1 finally nailed the SubdividePolygon() segfault when running as a dedicated
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.

Ozkan Sezer 2b919188d6 renamed Sys_FloatTime to Sys_DoubleTime (the thing always returned double
you know..) and adjusted all callers accordingly.  changed Sys_Sleep() to
take a milliseconds argument, added implementations for unix (usleep) and
windows (Sleep).

Ozkan Sezer 8e0638e867 gl_rmisc.c (R_Envmap_f): the envmap command can only be run when there's something
to render, ie. when connected to a server. besides, the refdef must be restored when
it is completed.
