Patch to 3.0.5 to add source ip to nsd-notify

Hi,

I patched nsd-notify similar to nsd-xfer. To be compliant with the existing code i haven taken
the code of nsd-xfer, which already supports the -a flag and binding to specific addresses.

Additional changes:

nsdc:
  - read "ip-address" in ${configfile} and give as arguments ("-a") to nsd-notify

nsd.conf.sample:
  - added note on "ip-address" which is now used for source-addres of nsd-notify

nsd-notify.8:
  - added -a flag

nsd-xfer.8:
  - added missing -a flag

Maybe it is a good idea to put

  check_matching_address_family

and

  *find_by_address_family

into their own new c-file, because nsd-xfer and nsd-notify are using them.
