move out-of-date hints files to the outdated folder.
rename the hints files, and hints/include files that are currently
named *.2020 to *.370 (next release number).
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.
On some platforms this may require:
make spotless
make fetch-lua
I did attempt to force a reminder message about the latter to
Makefile.top this time, and hope that works correctly for everyone.
Removed some of the temporary changes necessary due to 4 hour delay.
Added the specification of the working directory to avoid the change
in working directory behavior that occurs when checking out one
repository vs. two.
If checking out a single repository, the repository is checked out
to the path $(Agent.BuildDirectory)\s instead of
$(Agent.BuildDirectory)\s\<name of repository>. Modified checkout
to hard code path to avoid this change in behavior.
