nanny: change calloc() to xcalloc()
nanny: Do not update <client-into> and client-state> by default

Update only when new policy is to be applied by nanny
(device is explicitly enabled). Thus nanny update states
when it is responsible for configuration, and does not
update when ifup is doing it's job.

Merge pull request #180 from mtomaschewski/ifcfg

compat: allow backends return complete config
compat: read all suse ifcfg files and init timeout
leaseinfo: fixed typo in BOOTSERVERNAME variable
compat: blacklist all and default interface names
addrconf: avoid unwanted updates, update flag fixes

- Splitted addrconf updater type and update bitmap
- Defined the update flags in the schema and fixed
  to initialize to all known flags instead to ~0.
- Read several dhclient variables from suse ifcfg
  config such as update hostname (bnc#865325) and
  also diverse timing variables (not all used yet).
- Fixed extensions/hostname to verify its state and
  drop obsolete state to allow to switch to use a
  hostname from different lease (reconfiguration).
extensions: disabled writting of wickedd.log file
bonding: try to enslave into bond using netlink
bridge: do not require link-up on ports (bnc#862530)

Added workaround to not require link-up on all ports,
but device-up only or the bridge will be not set up.
