	* ripd.c: Untangle the construction of RIP auth data.
	  (rip_auth_prepare_str_send) new helper function, prepare
	  correct key string.
	  (rip_auth_simple_write) new helper, write out the
	  rip simple password auth psuedo-RTE.
	  (rip_auth_md5_ah_write) new helper, write out the
	  MD5 auth-header psuedo-RTE.
	  (rip_auth_header_write) new helper, write out correct
	  auth header data / psuedo-RTE.
	  (rip_auth_md5_set) rip out the memmove and writing of the
	  auth header psuedo-RTE. So that all that is left is to
	  write the trailing auth digest, and update digest offset
	  field in the original header.
	  (rip_write_rte) rip out writing of RIP header, writing of
	  simple auth data psuedo-RTE. Make it do what its name suggests,
	  write out actual RTEs.
	  (rip_output_process) remove the incorrect additional decrements
	  of rtemax. Prepare the auth_str, which simple or MD5 auth will
	  need. Move write out of RIP header and auth data to inside the
	  loop. Adjust paramaters as required.
