[2299] Use the shortcut DomainTree::find() for finding wildcard
[1894] Avoid expensive Name copy
[1894] Add LabelSequence version of NSEC3Hash::calculate()
[1894] Use a single LabelSequence object instead of doing costly name splits
[1894] Add missing method
[master] Wait for Xfrout ACL re-config to finish before sending out NOTIFY
[3274] Relay address can now be stored in Subnet structures.
[3301] Wait for new message XFRIN log messages

This reverts changes that were made in commit
199beea87baee4dd3d4339ec20c32d0d2cb47f40. It seems that commit removed
the wait for a "new" logged message, and introduced the regression in

Without waiting for a new log message, the check matches log messages
that were generated by initial AXFR during startup of the secondary
("bind10") instance.
[3242] Created a test library to create fake interfaces in IfaceMgr.
[3242] Added function to check that the iface's address belongs to subnet.
[3242] Implemented function which returns IPv4 address for interface.
[3242] Use new IfaceMgr::getAddress function in CfgMgr.
[3242] Implement function which returns subnet for the interface.

This function replaces the one that checked whether there is a subnet for
an interface and returns boolean value.
[3274] RelayInfo parser implemented.
[3242] Removed unused constant pointing to file carrying server id.
[3242] DHCPv4 server selects subnet for direct client using iface IP addr.
[3242] Adjusted unit tests to use correct subnets.

This change was necessary, because the recent changes to DHCPv4 imply that
subnet is selected for directly connected clients by matching the IPv4
address of the interface on which the message is received, with the
configured subnet.
[3274] Relay info support added to DHCPv4 parsers.
[2430] Support basic $GENERATE in dns::MasterLoader

It doesn't support format specifiers given in {} yet. This will be added
in follow-up work on this branch.

Relative names are not permitted in the RHS of $GENERATE
statements. This is because the string version of createRdata() is used
to construct RDATA, which does not take an origin.
[2430] Add lettuce test for $GENERATE
