The following patch:

1) adds "route-map" support to zebra
2) fixes "show route-map" (with no name arg)
3) adds "prefix-list" support zebra
4) adds a "set src" route-map command to allow specifying
     a source address for matched routes
5) adds "ip protocol" command to zebra to execute route-maps
     by protocol (or "any")
6) supports "interface", "nexthop" and "ip address" matching for
     zebra route-map's

	* thread.c: (general) Add support for monotonic clock, it may still
	  jump forward by huge amounts, but should be immune to going
	  backwards. Fixes bug #134.
	  (quagga_gettimeofday_relative_adjust) helper, does what name
	  says - adjusts gettimeofday based relative timer.
	  (quagga_gettimeofday) helper to keep recent_time up to date.
	  (quagga_get_relative) helper, update and getch the relative
	  timer using gettimeofday(). POSIX CLOCK_MONOTONIC is also
	  supported, but the code is not enabled yet nor tested.
	  (quagga_real_stabilised) helper, retrieve absolute time but
	  stabilised so as to never decrease.
	  (quagga_gettime) Exported interface, analogous to POSIX
	  clock_gettime() in interface, supporting several clocks.
	  (quagga_time) Exported interface, analogous to traditional
	  time(), will never decrease.
	  (recent_relative_time) Convenience function to retrieve
	  relative_time timeval, similar to existing recent_time absolute
	  timeval, for when an approximately recent value will do.
	  (remainder) Update to use above helpers.
	  (thread_getrusage) Previously was a macro, but needs to be
	  a function to twiddle with thread.c private stuff.
	* thread.c: Point the GETRUSAGE macro at previous function.
	  Export quagga_gettime, quagga_time and recent_relative_time for
	  general use.

	* thread.h: (struct thread) Add a cache pointer to the struct
	  cpu_thread_history, if it is known - saving hash lookup on
	  each thread_call.
	* thread.c: (thread_call) Cache the pointer to the
          cpu_thread_history, so that future thread_calls of same
          thread can avoid the hash_lookup.

	* vty.c: (vty_log_out) Do not call vty_close, because this could
	  result in a parent function's accessing the freed memory.
	  Instead, set status VTY_CLOSE and call shutdown(vty->fd, SHUT_RDWR).
	  And add a comment on vty_close.

	* vty.c: (vty_log_out, vty_read, vty_flush, vtysh_flush, vtysh_read)
	  After an I/O error, must set vty->monitor to 0 before calling
	  zlog_warn, otherwise an infinite recursion could occur
	  (since zlog_warn triggers a message to be written to the vty,
	  and that in turn triggers another error message when it fails, etc.).

2006-07-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* vty.c: (vty_log_out) Debug messages to terminal vty sessions
	  should include timestamps.

- entry was left in wrong order, according to date.

	* memory.c: Fix typo in cpp conditional around malloc.h, from
	  comment in bug #269.

2006-06-27 Paul Jakma <paul.jakma@sun.com>

	* route_types.awk: Fix previous commit. Forgot to remove the
	  printf of the bare/numeric route-type help string (empty string)
