Quagga 0.99.5 released

Quagga 0.99.5 has been released. Hypertext version of the summary as follows:

lib:
 major:
  [lib] Fix infinite recursion for errors on vtys with terminal monitor enabled (quagga-dev 4239)
  [lib] Do not call vty_close in vty_log_out to avoid possible free memory access (quagga-dev 4258)
 minor:
  [lib] vty_log shouldn't crash if called when vty isn't initiliased
 enhancement:
  [lib] Add support for Sun libc printstack to zlog_backtrace_sigsafe
  [lib] Optimise thread_call by caching pointer to thread history in the thread
  [lib] Bug #134: threads should be more robust against backward time jumps

zebra:
 major:
  [zebra] Fix forgetfulness wrt configured address on FreeBSD
  [zebra] Bug #268, Fix race between add/delete of routes, sanitise rib queueing
  [interface configuration] Preserve flag indicating address was set by quagga.
  [interface configuration] Try to avoid losing address info after shutdown.
 minor:
  [zebra] Connected routes must always be added to main table (quagga-dev  4276)
  [zebra] IRDP: Move stream_free to where its created, probably fixing a leak
 enhancement:
  [debug] Improve zebra kernel socket debug message to include IP addresses.
  [debug] Debug messages to terminal vty sessions should include timestamps (quagga-dev 4211)

bgpd:
 major:
  [bgpd] Fix crash on shutdown of peer
  [bgpd] Potential bug#287 fix, peer_delete should NULL out freed buffers
  [bgpd] aspath_loop_check was broken, fix it and the aspath unit test code.
 minor:
  [bgpd] fix mtype in XFREE and NULL out freed pointer
 enhancement:
  [bgpd] expand vty help for neighbor ... update-source
 known regressions:
  - peer prefix counts can drift, potentially dramatically when bgp
    dampening is not enabled. This is cosmetic, unless maximum-prefix
    is configured for any peer.
  - the 'shutdown' command may not work, sessions to shutdown peers can
    come up. Fix will be integrated to CVS after this release.

ospfd:
 major:
  [ospfd] Avoid getting NSM stuck in ExStart by using local view of DR/BDR (quagga dev 4196)
  [ospfd] Bug #288: do not change router ID unless forced by manual configuration
  [ospfd] Clear adjacency state for NSM changes down to TwoWay/ExStart (quagga-dev 4202)
  [ospfd] early-return in nsm_event missed LLDown event, fixes use after free (quagga-dev 4217)
 minor:
  [ospfd] Fix ospf passive-interface subcommand to create interface if necessary
  [ospfd] When writing out config, show "debug ospf nsm status" properly
  [ospfd] redistribute default no longer works after complete reconfig, fix (quagga-dev 4336)
  [ospfd] Fix multicast membership drop bug
  [ospfd] NSSA translate-enabled ABR should declare itself as ASBR
  [ospfd] lsdb_delete/discard_from_db should be more robust to bad args
  [ospfd] Fix "show ip ospf neighbor A.B.C.D" to show all matches
  [ospfd] Raise ExchangeDone earlier, avoid often needless round of DD packets
 enhancement:
  [ospfd] Implement new ospf router subcommand "log-adjacency-changes [detail]"
  [ospfd] Improve Hello NetworkMask mismatch warning to give more info (quagga-dev 4246)
  [ospfd] cleanup NSM neighbour delete through a new Deleted NSM state (quagga-dev 4218)
  [ospfd] record timestamp and event of last NSM state change for neighbour
  [ospfd] Additional NSM neighbour state change stats/information
  [ospfd] draft-ogier-ospf-dbex-opt DB-exchange optimisation
  [ospfd] Bug #134, ospfd should be more robust to backward time change
 known regressions:
  - bug #269: reports of ospfd crashing, apparently when loading large
    number of external LSAs. No one has yet confirmed whether the
    problem has been fixed or still persists.
