 - GenericLeaseMgrTest class moved to a separate file
 - @todo added for disabled tests in memfile (with explanations)
 - Added several comments

Removed configuration parameter allow-client-update.
It was deemed to really just be the inverse of override-client-update.
Renamed convenience method isDhcpDdns to ddnsEnabled.
Made enum to string converion functions case insenstive.
Updated copyright dates and other cosmetic changes.

Minor changes to logging messages, unit tests, and commentary.

Added support for lease type discrimination in IPv6 lease
operations in MySQL backend used by DHCP6, dhcpsrv/mysql_lease_mgr

 - LeaseType is now initalized from static array
 - @todos added in 2 MySQL tests
 - Added a comment about lease type values to MySQL schema

Also, cleaned up whitespaces.

Changes:
 - hwaddr.h - added MAX_HWADDR_LEN
 - hwaddr.cc - modified constructor to throw InvalidParameter
            if input address is too big
 - hwaddr_unittest.cc - added tests for new constructor throws

 - lease_mgr.h - removed HWADDR_MAX
 - mysql_lease_mgr.cc - added logic to set SQL mode to STRICT
 - tests/mysql_lease_mgr_unittest.cc - modified tests that were
    failing on STRICT mode, to expect exceptions.

and use the holder in the unit tests as well

  - hwaddr was mistaken as client-id again

- detailedLeaseCompare unified (alloc_engine and mysql_lease_mgr)
- comments clarified

this will suppress a cppcheck error:
http://git.bind10.isc.org/~tester/builder//BIND10-cppcheck/20121209143001-FreeBSD8-amd64-GCC/logs/cppcheck.out

okayed on jabber.

This is akin to the DuidPtr and is a shared point to a Client ID.

As the address is th eprimary key of the table, there can only ever
be at most one lease in the database with a given address.  Additional
selection by subnet ID is not needed.

Including:
* Updates to comments etc.
* Addition of Lease4::operator==() (and associated unit tests)
