version 0.5.25

• server: no unrequested device-ready events (bnc#871135)
  This bug caused e.g. bridges not going up from device-exists
  even they already were in device-ready state before.
• client: do not mix shared with exlusive references (bnc#877776)
• ifconfig: do not fail on delete for vanished devices
• nanny: drop policies on ifdown, turn some errors to debug
• sysconfig: add WICKED_DEBUG and WICKED_LOG_LEVEL variables
  to /etc/sysconfig/network/config.
• man: added ifcfg-{dummy,macvlan,macvtap,tunnel},ifroute,routes
  ifsysctl and updated already existing manual pages.
