SDL2 i_video.c code cleanup

Made some code look a bit neater, removed the need for some SDL2STUBs Fury placed, vid_info console command actually kind of has a use again, etc

See merge request !138

Revert "(Messiness warning) attempt to start using SDL_SetRelativeMouseMode instead of the old hacks of making the mouse do movement without leaving the window and be hidden"

This reverts commit 347b5318.

(Too experimental, may end up adding new bugs; let's just keep it to clean up for now)

(Messiness warning) attempt to start using SDL_SetRelativeMouseMode instead of the old hacks of making the mouse do movement without leaving the window and be hidden

Seems to work so far though

This way it's easier by eye to see from the list which SDL scancode maps to which SRB2 key code

(Apparently SDLK_LMETA/SDLK_RMETA don't exist anymore in SDL2 anyway?)

This means the console command vid_info also works properly too now (well, it does nothing in OpenGL mind)

Turns out sdl12's version of this function only did stuff for DC/GP2X ports; support for them have been cut out for SDL2, so for now let's just not use the function at all

HWR_DrawFill support for V_NOSCALESTART

This fixes the console selection highlighting being wrongly positioned and sized for OpenGL.

See merge request !135

Started work on making HWR_DrawFill support V_NOSCALESTART properly ...so far I've got the console text select highlight in the right place outside of 320x200 (and 320x200 is still fine), but for whatever reason it's too large in width and height

Oh well, we're part of the way there, anyway

Console improvements

* Unused console backgrounds no longer take up memory
* Input cursor can now move left and right
* Support for selections (Shift-arrow keys, CTRL-A, etc)
* Clipboard support (CTRL-C to copy, CTRL-V to paste, CTRL-X to cut)
* Fixed handling of simultaneous modifier key presses

None of this affects chat yet, that's not part of the console. I'll look at it later.

MD2 limits check hotfix

Fixing slight mistake made in merge request !132 that someone else spotted, no real explanation needed

See merge request !134

MD2 vertex/frame/triangle/etc limits checking

Fix for this bug: http://mb.srb2.org/showthread.php?t=42099

The model reading code didn't properly check if the model had too many vertices, so models with higher counts freely broke the game. This fix now stops that and prints an error message if that is the case.

However, it seems some models happily exceed other limits such as texcoords without problem (to my knowledge), so I've not bothered with checking those limits for now. Perhaps this could be a time to discuss if we need to change such limits again or not? Either way, one can easily uncomment my lines for checking texcoords/skins/triangles limits later if needed.

EDIT: I've allowed checking for triangle and frame limits too now, after some discussion.

See merge request !132

...your guesses should not be treated as errors.

+ bug fixes

Merge branch 'console-improvements' of http://git.magicalgirl.moe/STJr/SRB2 into console-improvements

# Conflicts:
#	src/sdl/i_system.c

This keeps my new error messages from flooding the console and log.txt

I added similar checks for the other num* but it seems some MD2s break the other limits without knowing anyway ...so I've commented these checks out for now, unless we have further discussion regarding them later on

(unfinished, but basics work)

Revert "Chat and console improvements"

Chat and console improvements

now also properly handles L/R simultaneous presses

let's be honest, it's pretty dumb to have every single possible back colormap in memory when only one is being used at a time

You can now move the cursor in command prompt and chat, using left/right, ctrl+left/right, home/end, and select text with shift
