[render] Add basic 2d line drawing
...
The software renderer uses Bresenham's line slice algorithm as presented
by Michael Abrash in his Graphics Programming Black Book Special Edition
with the serial numbers filed off (as such, more just so *I* can read
the code easily), along with the Chen-Sutherland line clipping
algorithm. The other renderers were more or less trivial in comparison.

Nuke the rcsid stuff.

It's pretty useless in git.

No clients link. Even if they did, nothing would work.

Add functions to create/destroy qpics.
...
The creation uses raw 8-bit data (and the system palette). Destroying a
qpic loaded via other means will probably produce nasal demons.

Allow uncaching of qpics.
...
qpics loaded via Draw_CachePic can now be uncached via Draw_UncachePic.

Revamp cshifts and implement in glsl.
...
The renderer should now be free of any direct access to client code. Even
3d rendering is now done via a function pointer.
The cshift code is done as a 2d screen function.

make gamedir change a two phase operation so things can be done both before and after the cache is flushed. (still having problems with cached sounds, though)

Change hudswap to use a callback, and instead of passing a swap variable to 10 functions, where only 2 use it, use a global variable. Make a few scr functions static inline, too. Got a totally unexpected ~0.45fps speedup.

sw32. Flee in terror. This'll break compilation for everything until -sdl32 compiles. sw32 wont work for a while either, so don't get overly excited yet.
