What changed in EDuke32, build by build

Oops! Fix MinGW build issue caused by ripping out nedmalloc

A potential fix for MUSICANDSFX problems after loading a savegame. I was never able to reproduce the issue myself, but something like this seems like a good idea anyway. Thoughts?

Remove some outdated/incorrect code that was causing some issues when multiple copies of a single sound were playing and just one of them needed to be stopped.

Fix setting r_pr_maxlightpasses from .cfg at startup

Add cvar "cl_runmode" to control ud.runkey_mode. This should fix the "allow walk while running" preference not saving.

Fix the bug I caused with custom projectiles :p

Fix issue with explosion sound cutoff in E1L2. This implements functionality to stop playback and free up the voice of a currently playing sound of the same ID when there are already MAXSOUNDINSTANCES (currently 8) of the same sound playing, determined by distance/volume and which sound is oldest.

fix up Makefiles, split dynsymlists.

Minor cleanups in actors.c, mostly relating to custom projectiles and the like. A bug causing custom projectiles to knock the player back twice as far as the hard-coded ones was also fixed. There should be no other functional changes for the end user.

make 'corruptcheck_noalreadyrefd' a separate OSD command.

Fix a.masm changes so MSVC builds work again. The relevant functionality seems to work (non-power of 2 textures drawn without error), even with CLASSIC_NONPOW2_YSIZE_WALLS defined in engine.c, but I'm not familiar with any corner or edge cases that need to be watched out for with this.

engine.c: add compilation switches for non-pow2 ysize functions, disable for now.

Revert "Abyss crash prevention code", but make the overflow explicit.

Disable spot lights on ATI cards, fixing the recent crashes with Catalyst 12.8.

Fix compilation on Debian 6.0 (Squeeze).

Revert r2223's removing of bit 1 making it to setbrightness(), now a noop.

Fix aspect determination from showview in fullscreen mode.

Fix three (probably harmless) maybe-uninitialized warnings.

Possible fix for saving the "Fav priority" autoswitch setting.

__fastcall int32_t getangle -> int32_t fastcall getangle. Might fix MSVC build.

New OSD cmd: demo <demonum or demofile>, starting one instantly from the menu.

Fix entering the game from within a demo, but don't enable it.

Use Bstrncpyz in 1 place; fix displaying err msg if write-opening savegame fails

Fix crash when recording demo, stooping it, going to title screen, and exiting.

Fix "shooting" tripbombs from non-players such as the SE shooter.

The Build tools no longer link with SDL or SDL_mixer because they don't need to.

Disable questionable lines from Makefile.common that were causing my build system to deep crash.

for c&p-ing map portions w/o TROR, fix wrongly resetting wall lotag/extra

for copy-pasting map portions without TROR, fix wrongly resetting xpanning.
