The "modify" command allows you to replace an existing record
(its hostname, sub-elements). IP address acts as the primary key.
If it is not found, the attempt ends with an error message. If
the XML contains a duplicate address, it will select the last
one.
Tests in networkxml2xmlupdatetest.c contain replacements of an
existing DNS-Host record and failure due to non-existing record.

virSocketAddrGetRange() has been updated to take the network address
and prefix, and now checks that both the start and end of the range
are within that network, thus validating that the entire range of
addresses is in the network. For IPv4, it also checks that ranges to
not start with the "network address" of the subnet, nor end with the
broadcast address of the subnet (this check doesn't apply to IPv6,
since IPv6 doesn't have a broadcast or network address)
Negative tests have been added to the network update and socket tests
to verify that bad ranges properly generate an error.
