What changed in EDuke32, build by build

Fix the bug I caused with custom projectiles :p

The other half of the previous commit.

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.

expose updatesector*, add random walker as timing test for them.

various tweaks and API changes/additions.

save command input history.

Clean up redundant/local function declarations in build.c.

various tweaks.

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.

In savegames, store dummy constant-length block instead of a _prlight array.

In DNCOORDS display, add spritebridge and sbs.

On non-{Windows, OS X}, don't link to libpng when PNG support is not requested.

Add helper program profdemo.lua, running EDuke32's demo profiling N times.

In Load Game menu, show 32- or 64-bitness of save game on mismatch.

make 'corruptcheck_noalreadyrefd' a separate OSD command.

factor out some code (3x) into GetSaveBoardFilename().

In -d command line arg, allow specifying demo number in addition to file name.

Update ENet with the latest changes from github

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: Split CLASSIC_NONPOW2_YSIZE into _WALLS and _SPRITES, enable the second

Port non-pow2 ysize texture mapping routines to MASM, untested.

a.nasm: add 'dword' to some stores in the nonpow2 routines for consistency.

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

foreachmap.lua: add option of only printing matching file names (like grep -l)

add check for sprites being out of the maximal grid range (+-524288).

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.

Add the option of starting demo profiling from the command line.

foreachmap.lua: add shortcut for quickly finding certain sectors/walls/sprites.

With SDL 1.2 builds, make the profiling be cancelable by pressing any key.

Add a profiling option to the 'demo' OSD command.

Fix aspect determination from showview in fullscreen mode.

Remove old backtrace DLLs. For some time they have been unused and supplanted by ebacktrace1.dll.

Add detection of Windows 8 and Server 2012 to win_printversion().

Fix three (probably harmless) maybe-uninitialized warnings.

patch from jfmact: "added c++ trimming to header" mathutil.h

Revise EVENT_CHANGEWEAPON so that RETURN has no effect except for two values. -1 will cancel the weapon switch. -2 will override the switch to whatever value p->curr_weapon is set in the course of the event.

SE17 setup: when failing to find warp z height for lower level, use heuristic.

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

Replace some literal statnums with the corrensponding STAT_...

Replace some more literal SE numbers, rename a couple of functions.

STHELP.HLP/SEHELP.HLP: reference SE11 and ST23 from each other.

Replace most other literal SEs/STs by symbolic enumeration values.

Clean up some timing-related code.

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

Move enum cheatindex_t from game.c to game.h and use its values in osdcmds.c.

Add macro CON_ERRPRINTF(Fmt, ...) and use that everywhere.

Factor out some repeated code into G_{Load,Save}PlayerMaybeMulti.

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

Factor out snprintf'ing a maybe-modDir'd file name into macro G_ModDirSnprintf().

Move G_HandleAsync() into game.h as 'static inline' and use everywhere else.

Rename a couple functions local to actors.c, remove IFHITSECT macro. This is mostly a test commit to make sure our CIA.vc script is properly updated now.

compat.h: tweak indentation of some preprocessing directives.

Make getangle() a __fastcall function instead of static inline.

In dosetaspect(), bail out calculating radarang2[] instead of failing assertion.

Add lunatic/test/tables.lua, which was used to compare the calc'd sin/atan values.

Calculate sine and arctan tables, getting rid of TABLES.DAT dependency.

player.c: factor out inline checks for shootable switch picnums.

player.c: factor out multiple instances of a 3-liner into A_SetHitData().

Remove some unneeded NULL checks.
