r8076: Put name resolution methods into libnet_context. This allows libnet based

application use methods of their own choice and makes it less dependent on
smb.conf parameters.
Use libnet_context in libnet_Lookup functions which is the way to pass
default name resolution methods if caller doesn't want to bother with
specifying them.
