kea-dhcp4 will parse and use "queue-control" to configure ring
buffer size:
"Dhcp4":
{
"queue-control": {
# max number of packets the ring will hold
"capacity" : 100
},
:
This is an interrim commit for testing purposes.
Expect a fair amount of refactoring in subsequent commits.

New tests to make sure reservation matching behaves
according to reservation modes

Adding missed bits needed to parse HR_GLOBAL mode
- Added constants for special SubnetIDs:
SUBNET_ID_GLOBAL, SUBNET_ID_MAX, SUBNET_ID_UNUSED
- Modified code throughout to use these constants, rather than hard-coded
values. Note, MySQL and PostgreSQL host backends convert from NULL to
UNUSED and back.
- kea-dhcp4/6 servers will now parse a "reservations" element at the global
level.

kea-dhcp4
added support for max-reconnect-tries and reconnect-wait-time
to lease and host db parsers
Added a callback for when DB backends detect loss of connectivity
Added a self-rescheduling method to attempt to reconnect to the
backends if retries are enabled
dhcpsrv
Added a callback that DatabaseConnection derivations should invoke
when they lose connectivity.
Added an optional callback parameter from CfgDbAccess::createManagers()
all the way down to DatabaseConnection ctor.
pgsql_connection.cc
PgSqlConnection::~PgSqlConnection() - Added logic to close the
connection only when the connect state is still OK.
Otherwise it likes to core dump.
PgSqlConnection::checkStatementError() - Modified to invoke the
connectivity lost callback on "fatal" errors
pgsql_lease_mgr_unittest.cc
pgsql_host_data_source_unittest.cc
Added tests to verify that the lost callback is NOT invoked on an
open failure
