b7cc56d22d ctdb-server: Implement CTDB_CONTROL_START_IPREALLOCATE
Trigger a "startipreallocate" event, but only if in RUNNING runstate.
"startipreallocate" is intended to allow an NFS server to be put into
grace on all nodes before any locks are released as part of releaseip
during failover.  If node A is leader and initiates a takeover run
then node B may be connected/active but may not have completed
startup.  In this case, the attempt to put NFS-Ganesha into grace on
node B will fail, startipreallocate will fail, and the node will be
banned.

037e8e449d ctdb: add/implement CTDB_CONTROL_TCP_CLIENT_PASSED
With multichannel a tcp connection is registered first with
a temporary smbd process, that calls CTDB_CONTROL_TCP_CLIENT
first and then passes the tcp connection to the longterm smbd
that already handles all connections belonging to the specific
client_guid. That smbd process calls CTDB_CONTROL_TCP_CLIENT
again, but the 'tickle' information is already there.
When the temporary smbd process exists/disconnects from ctdb
or calls CTDB_CONTROL_TCP_CLIENT_DISCONNECTED, the 'tickle'
information is removed, while the longterm smbd process
still serves the tcp connection.

63255ef925 ctdb-daemon: Only consider client ID for local database attach
The comment immediately above this code says "don't allow local
clients to attach" and then looks up the client ID regardless of
whether the request is local or remote.

This means that an intentional remote attach from a client will not
work correctly.  No real client should ever do that since clients
attach so they an access databases locally.  Perhaps some sanity
checks should be added.

36938bfdd0 ctdb-server: Rename CTDB_BROADCAST_VNNMAP -> CTDB_BROADCAST_ACTIVE
This broadcast is misnamed.  Both places where this type of broadcast
is used expect the broadcast to go to all active nodes.

Make the corresponding change to the semantics in the daemon by
sending to all active nodes.

There is a mismatch between the ideas of VNN map and active nodes.  A
node that is not in the VNN map but is active can still host database
records.  These were the same until the LMASTER capability was
introduced and then the logic was not updated.

The only place where the VNN map is relevant is when finding the
location master of a record in the migration code.
