2005-04-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	Implement non-blocking zclient I/O with buffering.
	* zclient.h (struct zclient): Add two fields to support non-blocking
	  I/O: struct buffer *wb, and struct thread *t_write.
	  (zclient_free): Remove function.
	  (zebra_redistribute_send): Change 2nd arg from socket fd to
	  struct zclient * (needed to support non-blocking I/O and buffering).
	  (zclient_send_message): New function to send an arbitrary
	  message with non-blocking I/O.
	* zclient.c (zclient_new): Create write buffer.
	  (zclient_free): Remove unused function.
	  (zclient_stop): Must cancel new t_write thread.  Also, reset
	  all buffers: ibuf, obuf, and wb.
	  (zclient_failed): New helper function for typical error handling.
	  (zclient_flush_data): New thread to flush queued data.
	  (zclient_send_message): New function to send the message in
	  zclient->obuf to zebra using non-blocking I/O and buffering.
	  (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use
	  new zclient_send_message function instead of calling writen.
	  (zclient_start): Set socket non-blocking.  Also, change 2nd arg
	  to zebra_redistribute_send from zclient->sock to zclient.
	  (zebra_redistribute_send): Change 2nd arg to struct zclient *.
	  Can now use zclient->obuf to assemble the message instead of
	  allocating a temporary stream.  And call zclient_send_message to
	  send the message instead of writen.
	  (zclient_read): Convert to support non-blocking I/O by using
	  stream_read_try instead of deprecated stream_read.
	  (zclient_redistribute): Change 2nd arg to zebra_redistribute_send
	  from zclient->sock to zclient.
	* ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute):
	  Change 2nd arg to zebra_redistribute_send from zclient->sock
	  to zclient.
	* ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead
	  of writen.
	* rip_zebra.c (rip_redistribute_set, rip_redistribute_unset,
	  rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send
	  from zclient->sock to zclient.
	* ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean):
	  Change 2nd arg to zebra_redistribute_send from zclient->sock
	  to zclient.
	* bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset):
	  The 2nd arg to zebra_redistribute_send is now zclient instead of
	  zclient->sock.
	* isis_zebra.h (isis_zebra_finish): Remove declaration of unused
	  function.
	* isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message
	  to send the message to zebra instead of calling writen directly, since
	  zclient_send_message understands non-blocking I/O and will manage
	  the buffer queue appropriately.
	  (isis_zebra_finish): Remove unused function, particularly since
	  the zclient_free function has been removed.
