Cosa è cambiato in EDuke32, build per build

getcwd with NULL gives us memory allocated from the system, so don't try to use nedmalloc to free it.

Fixes former crash in drawline16 and swaps drawpixel with the unsafe variant there; fixes potential sector[-1] access in sliding Star Trek doors; make CC overridable in Makefiles so that other toolchains or static analyzers like scan-build/clang can be used; with its help, fix some issues, some more severe than others.

Fix a bug where having two or more lighting passes on a multi-surface mdsprite would leak some GL state and disable blending for all but the first surface.

This commit doesn't add anything interesting for anyone not interested in tracing down completely absurd bugs.

More sensible dragging in side view mode. When pasting walls in 3D mode, match the actual pixel width of the source wall.

Fix digitalnumberz spacing and saving/loading of screen size

Adds chselshade (change selected shade) to a.m32

A week worth of Mapster hacking: first, there is an experimental side view mode toggled with [F3]. Nav keys are {QWAZ}, MMB and RMB. Use with care because it is still in construction. The sector selection routines have been rewritten -- it is now possible to paste the selection into a room and a new inner loop will be added automatically (MickyC's idea). Adds m32script commands drawline16z and drawcircle16z.

remove obsolete CON compile warnings about affecting multiplayer sync, add -nodinput compatibility parameter to work around DirectInput crash issues on certain systems, fix http://forums.duke4.net/index.php?s=&showtopic=2961&view=findpost&p=60752

Set union ['] and difference [;] for sector selection in Mapster32; probably fix for crash on clipshape-init; replace tabs in doc/build*.txt with three spaces.

pass NEDMALLOC variable to build/Makefile

a.m32 corruption checker: also handle out-of-range picnum

Use posix_memalign in fork/exec midi player when not using nedmalloc. This fixes compilation in this case for me.

Works around a bug with newer NVIDIA GL drivers where creating a GL context

Delete _clipshape_.map. Easy to forget if it's not on the file system anymore...

Fixes quite a few nasty bugs with the new clipping code, including the crash. Clip shapes are now loaded from _clipshape0.map through _clipshape9.map (no break like when loading tiles, just see if each is present). Mapster32: insert some safety code for sprites with sectnum<0. Because this is still a bad thing, have the m32script corruption checker catch this and run it periodically from EVENT_DRAW2DSCREEN. Also draw such sprites in 2D mode with a blood-red color, and make them draggable. Remove set[sector,wall,sprite] commands.

New sprite clipping for hitscan; crude debugging code for tracing down the crash that Commander is getting and I can reproduce only in real Windows with the synthesis build.

Fix crash. Reason was obsolete code.

Sector-like sprite clipping. Check samples/spriteclip.txt.

Temporarily replace drawpixels by a bounds-checked version in engine.c.

Don't reset extra tags before loading map in Mapster32.
