clean up the draw interface a bit

/*
Make a start on putting the pieces together. Still many undefined and multiply defined symbols, but there seems to be a light in this darkness. I just hope it's not an oncoming train :)

[renderer] Remove namehack.h Finally. I never liked it (felt bad adding it in the first place), and it has caused confusion with function and global variable names, but it did let me get the render plugins working.

struct qpic_s;
[renderer] Add Draw_AddFont for registering a font It's implemented only in the Vulkan renderer, partly because there's a lot of experimenting going on with it, but the glyphs do get transferred to the GPU (checked in render doc). No rendering is done yet: still thinking about whether to do a quick-and-dirty test, or to add HarfBuzz immediately, and the design surrounding that.

struct rfont_s;
[renderer] Add a cell-based character buffer This is intended for the built-in 8x8 bitmap characters and quake's "conchars", but could potentially be used for any simple (non-composed characters) mono-spaced font. Currently, the buffers can be created, destroyed, cleared, scrolled vertically in either direction, and rendered to the screen in a single blast. One of the reasons for creating the buffer is to make it so scaling can be supported in the sw renderer.

[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.
