Ingo Paschke 2d597cb9fa Revive Amiga port for NetHack 3.7 
Update the Amiga Intuition window port (AMII/AMIV) for the 3.7
window_procs API. Key changes:

- Update all window function signatures for 3.7
- Add assembly trampolines for AmigaOS register-based callbacks
- Convert all K&R function definitions to C99
- Add cross-compilation build system (cross-pre1/pre2/post.370)
  using bebbo's m68k-amigaos-gcc with -noixemul -std=gnu17 -m68000
- Clipping fixes: viewport centering, simplified ScrollRaster,
  duplicate Ctrl-R suppression, glyph buffer invalidation
- Add menucolor support in menu rendering
- Move native txt2iff.c and xpm2iff.c to outdated/
- Add nethack.cnf and README.amiga

* Begin Revamped Text display routines
*
* Up until version 3.1, the only method for displaying text on the playing
* field was by using the console.device. This was nice for a number of
* reasons, the most signifigant of which was a lot of the nuts and bolts was
* done for you via escape sequences interpreted by said device. This did
* not come without a price however. And that price was speed. It has now
* come to a point where the speed has now been deemed unacceptable.
*
* The following series of routines are designed to drop into the current
* nethack display code, using hooks provided for such a measure. It works
* on similar principals as the WindowPuts(), buffering I/O internally
* until either an explicit flush or internal buffering is exceeded, thereby
* forcing the flush. The output (or glyphs) does not go to the
* console.device, however. It is driven directly to the rasterport of the
* nethack window via the low-level Text() calls, increasing the speed by
* a very signifigant factor.
