win32: implement util.getfstype()
This will allow NTFS to be added to the hardlink whitelist, and resume creating
hardlinks in transactions (which was disabled globally in 07a92bbd02e5; see also
e5ce49a30146). I opted to report "cifs" for remote volumes because this shows
in `hg debugfs`, which also reports that hardlinks are supported for these
volumes. So being able to distinguish it from "unknown" seems useful.
The documentation [1] seems to indicate that SMB isn't supported by these
functions, but experimenting shows that mapped drives are reported as "NTFS" on
Windows 7. I don't have a second Windows machine, but instead shared a temp
directory on C:\. In this setup, both of the following were detected as 'cifs'
with the explicit GetDriveType() check:
Z:\repo>hg ci -A
C:\>hg -R \\hostname\temp\repo ci -A # (without Z:\ being mapped)
It looks like this is called 6 times to add and commit a single new file, so I'm
a little surprised this isn't cached.
