Complete the current working on using the basic logging system
for messages from LFC

Add lease_stats to provide a class to gather statistics
about reading and writing leases to files.  Currently this
is used by the CSV file code and output by LFC.  The
information counted is: number of attempts, number of leases
and number of errors generated during reads and writes.

Also added an utility class to bulk load leases from the file.

 - Moved MAC operations to a new CfgMACSource class
 - Moved macros to HWaddr class
 - Added several unit-tests for MAC sources
 - MAC extraction code moved to separate function in Dhcpv6Srv

This change affects many files using the Configuration object and types
derived from it.

- added --with-kea-config=JSON,BIND10 added to configure.ac
- JSON-file config backend added for b10-dhcp6
- Config file can now be read from a JSON file

 - patch contributed by David Carlier (thanks!)
 - updated to current master
 - fixed compliation issues
 - written developer's guide (pgsql setup steps)
 - many smaller changes
 - still WIP

d2_client.h and .cc was split into four files:

D2ClientConfig class is now in d2_client_cfg.h/cc
D2ClientMgr class is now in d2_client_mgr.h/cc

Added configuration paramters to dhcp4 and its spec file to support DHCP-DDNS.
Created new classes D2ClientMgr, D2ClientConfig, and D2CientConfigParser in the
libdhcpsrv.   The new parameters are parsed, validated, and stored  but do
not yet affect behavior.  That will be implemented as a seperate ticket.
