Corinna Vinschen 18df393573 * syscalls.cc (start_transaction): Make inline function. Move up to be
more generally available.
	(stop_transaction): Ditto.
	(unlink_nt): Potentially start transaction when trying to delete file
	with DOS R/O attribute set.  If file is .lnk symlink, check for number
	of hardlinks.  Add "out" label and only return via "out".  Rearrange
	reversion of DOS R/O attribute and, on success, only revert R/O
	attribute if file is .lnk symlink with more than one hardlink.  Add
	length comment to explain why.
