[model] Remove 64k limit on visible leafs Modern maps can have many more leafs (eg, ad_tears has 98983 leafs). Using set_t makes dynamic leaf counts easy to support and the code much easier to read (though set_is_member and the iterators are a little slower). The main thing to watch out for is the novis set and the set returned by Mod_LeafPVS never shrink, and may have excess elements (ie, indicate that nonexistent leafs are visible).

The map's entities are used to create the lights, and the PVS used to determine which lights might be visible (ie, the surfaces they light). That could do with some more improvements (eg, checking if a leaf is outside a spotlight's cone), but the concept seems to work.

[vulkan] Rework lighting model to be more algebraic This leaves only the one conditional in the shader code, that being the distance check. It doesn't seem to make any noticeable difference to performance, but other than explosion sprites being blue, lighting quality seems to have improved. However, I really need to get shadows working: marcher is just silly-bright without them, and light levels changing as I move around is a bit disconcerting (but reasonable as those lights' leaf nodes go in and out of visibility).

[vulkan] Implement all the extended light models Standard quake has just linear, but the modding community added inverse, inverse-square (raw and offset (1/(r^2+1)), infinite (sun), and ambient (minlight). Other than the lack of shadows, marcher now looks really good.

The work also paves the way for qwaq-x11 to become a proper engine (though sorting out its init will be taken care of later). Fixes #15.

[vulkan] Create shadow maps and basic data I will definitely need to look into sparse images later (2.3GB for marcher) but the shadow map images, views and matrices are created.

[vulkan] Move non-specific lighting code out of Vulkan The parsing of light data from maps is now in the client library, and basic light management is in scene. Putting the light loading code into the Vulkan renderer was a mistake I've wanted to correct for a while. The client code still needs a bit of cleanup, but the basics are working nicely.

[vulkan] Load the map's lights into an array It's not used yet as work needs to be done to better support generic entities, but this is the next step to real-time lighting (though, to be honest, I expect it will be too slow to be usable).
