include/.gitignore should continue to ignore old files in case
someone checks out an older version, builds, then checks out the
current version without running 'make spotless' first.
sys/unix/Makefile.utl: tiletxt.o depends on tilemap.c in addition
to tiletxt.c.
Ignore the new timestamp files src/moc.qt5 and src/moc.qt6. They
probably ought to be renamed Qt*.moc-t but I haven't done that.
Also put back vis_tab.* in case someone checks out 3.6 and builds
that, then checks out 3.7 without doing 'make spotless' first.
Update makdefs source and its man page.
Remove all mentions of the vision table files from:
o .gitattributes
o .gitignore
o Files
o Cross-compiling
Add a brief note in the fixes file.
Add a couple of missing .gitignore entries for files put into
place when building. include/tile.h is genearated for tiles
and dat/NetHack.ad is copied for X11 resource definitions.
Part II of the bones tracking patch. Change umpteen different outrip()
routines to handle its new time_t argument, and use formatkiller() instead
of directly accessing killer.{format,name} and killed_by_prefix[]. The
latter is now static within formatkiller().
The many sys/* and win/* changes are untested....
