v23 of renderer patch

v23.

This one includes FBO support, mostly taken from xreal, though modified.  Using
this code, the renderer now renders to an fp16 frame buffer and does tone
mapping as a post-process.

The cvar r_hdr has changed, it now has four settings:
0: no tone mapping/hdr
1: tone mapping, autoadjust if worldspawn has "adaptiveToneMapping 1" key/value
pair, default
2: tone mapping, no autoadjust
3: tone mapping, autoadjust
This is to adapt to existing maps, so they don't have auto-adaptation when they
weren't made for it.

As well, r_lightmap 3 now shows the deluxemap for debugging purposes, though
this should not be used at the same time as hdr.

There are also some cvars for turning on/off the new GL extensions I use,
namely r_ext_framebuffer_object, r_ext_texture_float, and
r_arb_half_float_pixel.
