Reimpl. the cvar alias system. Reimpl. the cvar hash table as a distinct type
It is now type-safe, cleaner, and doesn't require new static cvar_t's
for each alias. The hash table being implemented as a distinct type
allows multiple hashes to point to the same cvar without having to
create a new cvar_t for each alias.

Initial implementation of cvar aliases, with slowmo as a starting example
This allows cvars to be renamed, and keep the old cvar by pointing it to
the new one. Pretty much every cvar finding function has been adapted to
return a the aliased cvar or the alias itself depending on context.
For example, if a value is needed, it'll dereference the alias. If the
cvar is needed to be listed somewhere or to check if the cvar merely
exists, it will not. Other than that, it's pretty straightforward.

Implement experimental hook-like system, with working example.
This system allows you to call functions that may or may not exist at runtime
and compile-time. You create hook_t pointers and register them during
initialization, and point them to a function. If they're not registered,
no problem. This could potentially allow different subsystems to function
independently of each other, such as the client and server.
It's using a union to allow functions to have any return type they want.
However, for obvious reasons, functions cannot have any parameters they want
and must accept a pointer to the union type where the actual args are stored.
This is experimental and there may be bugs, but the current working example
should be stable.

Added lightgrid texture based lighting in q3bsp maps by uploading it as a 3D texture, to make more accurate and continuous model lighting throughout a scene. Can be disabled via the mod_q3bsp_lightgrid_texture cvar.
The lightgrid texture based lighting can also be enabled on world surfaces if one desires (mod_q3bsp_lightgrid_world_surfaces cvar) which gives levels a dream-like quality that is globally consistent, can also be enabled for bsp models that are not the world (mod_q3bsp_lightgrid_bsp_surfaces cvar) which may be more useful for ammo pickup models that are bsp or similar.

Fix most Q3 & QL glow maps
From bones_was_here: "Very few glow maps work in unmodified Q3 maps as they do not use the _glow darkplaces convention, instead Q3 shaders specify the file name to use which is not currently supported.
Fortunately there is a naming convention started in id software's pak0 and continued in QL and most 3rd party maps. It uses these forms: foo_texture.blend.ext and bar_texture_blend.ext
It's not possible to fix 100% of glow maps without parsing Q3 shaders and using the specified file name, but this is a big improvement.
This also fixes a few glow maps in nexcompat, which are originally Q3 textures that were not renamed to _glow."

Allow r_viewscale to be set to values higher than 1 for super-sample antialiasing, also integrate vid_samples into this calculation to restore old behavior somewhat (super-sampling is more expensive than multisampling, so this isn't a great solution yet, but it brings back the quality).

Add csqc_polygons_defaultmaterial_nocullface cvar which defaults to 1 in nexuiz and xonotic derived games, this restores the compatible behavior with older versions of the engine. It defaults to 0 in other games (and would be recommended to set to 0 in those games when they make a new release) as it seems like that would be the better default for efficiency (and matches FTEQW engine).
Fixed a bug in CL_MeshEntities_FinalizeRenderEntity where it skipped finalize when the entity has no surfaces, but since it is still included in the render entities list it was rendering garbage when unused.

Rework r_shadow_shadowmode to be more maintainable and understandable - it now caches the values of r_shadow_shadowmapping and r_shadow_deferred, and is now updated when those change, rather than just at startup, and changing those now also causes a recompile of world lights (which always had different bounds when shadowing was on/off, toggling shadows had weird behavior as a result, so this is a bugfix).
This fixes a massive fps drain with settings that disabled shadows entirely by disabling shadowmapping (where r_shadow_shadowmapping 0 and r_shadow_deferred 0 together caused it to reallocate the shadowmap texture every frame and do other bad stuff)
