`tramp-copy-recursive'.  Valid for "rcp", "scp", "scp1", "scp2",
"scp1_old", "scp2_old", "rsync", "rsyncc".
(tramp-default-method): Check also for
`auth-source-user-or-password'.
(tramp-file-name-handler-alist, tramp-file-name-for-operation):
Add handler for `copy-directory'.
(tramp-handle-copy-directory): New defun.
(tramp-do-copy-or-rename-file-out-of-band): Handle directory case.
(tramp-handle-start-file-process): Raise an error when PROGRAM is
nil.  Optimize sent command.
