rename sys/winnt to sys/windows
move vs (visual studio) folder out of win/win32 and into sys/windows
rename include/ntconf.h to include/windconf.h
rename winnt.c to windsys.c
place visual studio projects into individual subfolders.
This will hopefully resolve GitHub issue #484 as well.
Get rid of vis_tab.{c,h}, also the commented out remnants of
{dgn_comp,lev_comp}.*, and put back sfstruct.* that erroneously
got removed along with some other stuff way back when.
Untested, and the lua stuff needs to be modularized.
I was looking into adding a confirmation prompt for '!' and it
isn't very promising due to sequencing issues. (The check for
whether '!' is allowed should happen before the prompt about
running it but the latter should take place in the core rather
than in the port code.) In the mean time, I noticed that VMS was
ignoring the SHELLERS value from SYSCF.
Untested implementation of a SHELLERS check on VMS. Even if it
works, it should not be using $USER as the user name to verify.
Tweaks the Unix implementation of check_user_string() but doesn't
switch the testing loop to the simpler version used by VMS which
is derived from the generic users test used by Qt.
Preparation for moving enlightenment and conduct into new source
file insight.c. Right now it's a stub that shouldn't break anything
whether included or omitted. Once makefiles and project files have
been updated to compile and link it, the actual code will be moved.
unix/Makefile.src has been updated;
vms/Makefile.src and vmsbuild.com have been updated but not tested.
Replace a few tabs, remove a few trailing spaces, and shorten a few
long lines.
Readme still needs another fix: if falsely claims to contain all bug
fixes since 3.6.4. I wasn't sure how to reword that so didn't try.
Also, fix a couple of old typos in Install.vms.
