[CIFS] improve setlease handling
fcntl(F_SETLEASE) currently is not exported by cifs (nor by local file systems) so cifs grants leases based on how other local processes have opened the file not by whether the file is cacheable (oplocked). This adds the check to make sure that the file is cacheable on the client before checking whether we can grant the lease locally (generic_setlease). It also adds a mount option for cifs (locallease) if the user wants to override this and try to grant leases even if the server did not grant oplock. Signed-off-by: Steve French <sfrench@us.ibm.com>

Various fixes to make delete of open files behavior more predictable
(when delete of an open file fails we mark the file as "delete-on-close"
in a way that more servers accept, but only if we can first rename the
-file to a temporary name)
+file to a temporary name). Add experimental support for more safely
+handling fcntl(F_SETLEASE).
