1679.	[func]		fdupont
	Added new commands to the lease_cmds hooks library to search for
	leases by hardware address, client-id, DUID and hostname. Note
	that now in leases hostnames are stored in lower case, e.g.
	the MySQL hostname columns are now lower case.

1676.	[func]		fdupont
	A new hook - flex-option - has been developed. It allows setting
	up DHCPv4 and DHCPv6 option values dynamically, using expression.
	This capability is very useful when you want to generate option
	value procedurally. For details, see new section "Flexible Option
	for Option value settings" in the Kea Administrator Reference
	Manual.

	coroutine.hpp from Boost 1.68 has been added the Kea source.
	It is used only if the Boost library provided by the system

	Added initial implementation of congestion handling to kea-dhcp4
	and kea-dhcpt6. This adds a new top level element to the server

	queueing them for server level processing.  For Kea 1.5-Beta
	this feature is always on.

	Improved lease database synchronization mechanisms in High
	Availability hooks library. The new implementation uses
	lease4-get-page and lease6-get-page commands to fetch leases

	memory consumption on the HA enabled servers during lease

	Dependencies improved. libkea-process no longer requires libkea-dhcpsrv.
	As a result, D2 and CA are no longer linked with libkea-dhcpsrv.
	(Gitlab #25,!14, git cdb3a6f2d98a303b80433df7e0d5698c77897b7f)

	Modified Kea 1.5.0 database upgrade scripts to convert
	subnet ID values of 0, to either null (MySQL and Postgres)
	or 0xFFFFFFFF (CQL), in existing host reservations. This
	is done to accommodate support for global host reservations.
	(Gitlab #15,!11, git 25b54fd9ced4c6d3a2c8ceff9cc7c866b56da2c1)

1448.	[build]*	marcin
	Created new Kea libraries: libkea-database, libkea-mysql,
	libkea-pgsql and libkea-cql. Some database specific code was
	moved from libkea-dhcpsrv to those new libraries.

	kea-dhcp6 now supports global host reservations and a new
	global reservations-mode .  Prior to this reservations could
	only be specified per subnet.  This is supported by by Memfile,
	MySQL, PostgreSQL, and Cassandra host data sources.

	Implemented initial skeleton version of the kea-netconf tool.
	Currently it can't do anything, but the build system is now
	capable of detecting sysrepo (use --with-sysrepo in configure),
	there's a very basic documentation and unit-tests.

	The internal representation of an "unused" subnet-id has been
	changed from zero to 0xFFFFFFFF. The largest, valid value for
	a subnet's ID is now 0xFFFFFFFE.  Three new constants have been
	added so subnet_id.h:

	isc::dhcp::SUBNET_ID_GLOBAL
	isc::dhcp::SUBNET_ID_UNUSED
	isc::dhcp::SUBNET_ID_MAX

	which should be used in code/hooks in place of hard-coded values.

	subnet-id parameter is now optional in lease4-add, lease6-add,
	lease4-update and lease6-update commands. If not specified or
	its value is zero, Kea will attempt to figure out the correct
	value of subnet-id. If there is no matching subnet configured,
	the lease will be rejected.

	DHCPv4 and DHCPv6 servers are now able to sanity check and
	possibly correct some inconsistencies in leases when loaded from
	disk (memfile). A new parameter to govern this behavior has been
	added.

	Added two new configuration parameters to kea-dhcp4 and kea-dhcp6
	DhcpDdns sections: 'hostname-char-set' and 'hostname-char-replacment'.
	These values (when not empty) are used by the server to sanitize
	host name and FQDN domain names sent by clients prior to using them
	to construct DNS names.

	Resolved multiple problems causing slow synchronization of

	Also, introduced 'sync-timeout' configuration parameter
	into HA hooks library to control lease database
	synchronization timeout.

	Added KNOWN and UNKNOWN built-in client classes: after host lookup
	if a matching host entry is found the incoming packet is added to
	the KNOWN class, if none is found to the UNKNOWN class. Then
	expressions depending directly or indirectly on these classes are
	evaluated. Note these classes may be used to select a pool but
	they may not to select a subnet.
