	ChangeLog

One of the major changes was to eliminate possibility of defining the dead
reservation: neither hostname nor IP address reserved and covering it with
suitable unit tests.

Removed the leftover debugging statement. Also, added some more commentary
to the test checking behavior for too long FQDNs.

Multiple updates to the documentation of the HostMgr. Also fixed a broken
implementation of the HostMgr::getAll4.

The following issues causing failures on the FreeBSD were corrected:
- Don't use sed to replace tabulations from the returned kea version.
Instead the CONCAT mysql function is used.
- Replace &>dev/null with the >/dev/null 2>&1

Additional changes:
- Added a new line before printing existing tables in the mysql.
- Added .gitignore for new files.

 - mysql/upgrade_1.0_to_2.0.sh renamed to .in
 - header added to admin-utils.sh, revoked exec bit
 - kea-admin clarified (db => lease db)
 - kea-admin manpage corrected
 - lease6_hwaddr_source renamed to lease_hwaddr_source
 - mysql_tests are now working without installation
