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.

[ui] Move font loading into new gui library Font and text handling is very much part of user interface and at least partially independent of rendering, but does fit it better with GUI than genera UI (ie, both graphics and text mode), thus libQFgui as well as libQFui are built in the ui directory. The existing font related builtins have been moved into the ruamoko client library.

struct font_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.

[console] Resurrect console scaling Currently only for gl/glsl/vulkan. However, rather than futzing with con_width and con_height (and trying to guess good values), con_scale (currently an integer) gives consistent pixel scaling regardless of window size.

[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 qboolean from orbit I never liked it, but with C2x coming out, it's best to handle bools properly. I haven't gone through all the uses of int as bool (I'll leave that for fixing when I encounter them), but this gets QF working with both c2x (really, gnu2x because of raw strings).

void glsl_Draw_Pic (int x, int y, struct qpic_s *pic);
[renderer] Add fitted pic rendering The pic is scaled to fill the specified rect (then clipped to the screen (effectively)). Done just for the console background for now, but it will be used for slice-pics as well. Not implemented for vulkan yet as I'm still thinking about the descriptor management needed for the instanced rendering. Making the conback rendering conditional gave an approximately 3% speed boost to glsl with the GL stub (~12200fps to ~12550fps), for either conback render method.

int glsl_Draw_AddFont (struct font_s *font);
[renderer] Replace Draw_FontString with Draw_Glyph While Draw_Glyph does draw only one glyph at a time, it doesn't shape the text every time, so is a major win for performance (especially coupled with pre-shaped text).

Rewrite the 2d code to use a scrap. This severely reduces the calles to BindTexture, and more importantly, glUseProgram, EnableVertexAttribArray etc. The biggest changes are: o icons and text are all in the one giant texture o icons and text are mixed in the one queue This gave ~9% speedup for bigass1 (159->174fps).
