Add DHCPv6 ntp-server (56) option handling.
...
There was discussion in the past regarding DHCPv6 NTP server option
which needs special subclassing per RFC5908.
Patch adds support for unicast, multicast IPv6 address and for FQDN string,
preserving possibly used (as suggested earlier) hex value.
Unfortunately it's still not fully free from limitations - only address list or
only fqdn value list is possible, not mixed due current
state option parsing & flagging.

Support prefixed ranges of ipv6 addresses in dhcp-host.
...
When a request matching the clid or mac address is
recieved the server will iterate over all candidate
addresses until it find's one that is not already
leased to a different clid/iaid and advertise
this address.
Using multiple reservations for a single host makes it
possible to maintain a static leases only configuration
which support network booting systems with UEFI firmware
that request a new address (a new SOLICIT with a new IA_NA
option using a new IAID) for different boot modes, for
instance 'PXE over IPv6', and 'HTTP-Boot over IPv6'. Open
Virtual Machine Firmware (OVMF) and most UEFI firmware
build on the EDK2 code base exhibit this behaviour.

Fix entries in /etc/hosts disabling static leases.
...
It is possible for a config entry to have one address family specified by a
dhcp-host directive and the other added from /etc/hosts. This is especially
common on OpenWrt because it uses odhcpd for DHCPv6 and IPv6 leases are
imported into dnsmasq via a hosts file.
To handle this case there need to be separate *_HOSTS flags for IPv4 and IPv6.
Otherwise when the hosts file is reloaded it will clear the CONFIG_ADDR(6) flag
which was set by the dhcp-host directive.
