Another round of filestat() fixen

Several changes to once-perlized, now-filestated tests:

	1. fix nlinks
	2. replace fctnl and lstat with filestat
	3. more instances of s/stat/filestat
	4. kill the common g zombie again
Inodes not supported on Win
Move uid/gid to !windows
Rm meta, not needed anymore
More filestat() work

Note about 115.cf — I have just broken this tc on all platforms, as the
path returned by filestat needs sanitizing.
filestat() work — symlinks
filestat() symlinks
More filestat() links work
