keepalived-0.6.9

* keepalived-0.6.9 released.
* Fixe some code dependence selection during compilation. If autoconf netlink
  probe fails then unset VRRP code.
* Cleanup daemon lib. Added some logging info for the daemon processing, removed
  some repeated code part.
* Added 2 new daemon arguments :
    --dont-release-vrrp : Dont remove VRRP VIPs on daemon stop
    --dont-release-ipvs : Dont remove IPVS topology on daemon stop
* Review the global scheduling process to clear FD queues on master thread
  destroy.
* Fixed a forking issue in the MISC_CHECK.
* Review IPVS wrapper functions to use allocated IPVS rules instead of static
  referencing pointer.
* Fixed the IPVS wrapper to delete IPVS entries according to their 'alive' state.
* Added IPVS support to alive flag for VS entries.
* Rewrote the previous main.c to support configuration reload on the fly. Extented
  signal handling to register a conf reload_thread on SIGHUP. The software design
  used here is a dynamic differential conf file reloading framework. This design
  offer key decision to add/remove new/old entries to/from low-level framework:
  IPVS topology and netlink IP addresses entries. This design reduce to the max
  the global service interruption since only negative diff entries are removed.
  For VRRP config reload on the fly, if you plan to add/remove many VIPs consider
  VIP declaration into the virtual_ipaddress_excluded since they are not present
  into VRRP adverts.
* Review the keepalived.init script to support restart and reload arguments.
* Fixed some typo issues.
