- upload only the dynamic AABB subtree using glBufferSubData
- change internal raytracing stack limit from 16 to 32
- update shadowmap AABB tree after R_SetupFrame for proper frame interpolation
Since these can be changed on the placed light actor they have to be read from there, so this is now a pointer in FDynamicLight, just like the other properties that can be user-changed.
Also did some cleanup on the interface so that external code doesn't need to dereference the lightflags pointer but can use utility functions for all flags.
This should be less of a drag on the playsim than having each light a separate actor. A quick check with ZDCMP2 showed that the light processing time was reduced to 1/3rd from 0.5 ms to 0.17 ms per tic.
It's also one native actor class less.

I thought this wasn't needed but apparently the buffer refactoring caused this not to be done automatically anymore.
Best have it once at the start of each frame where the cost is negligible.

* split gl_shadowmap.cpp into a GL dependent and an API independent part.
* gl_drawinfo must be kept around for the HUD sprite because it connects the renderer with the hardware indpendent part of the engine.
