2082c0c3b5 lib/util: Avoid splitting tevent-unix-util as public library
BUG: https://bugzilla.samba.org/show_bug.cgi?id=11946

Commit 670db6ac1d split tevent-util public
library to create tevent-unix-util public library for standalone ctdb
use.  This created a public library dependency between samba and ctdb
for packaging.

Bundle tevent_unix.c in public library tevent-util as before.  However,
to avoid the dependencies for packaging, standalone ctdb build will
build tevent-util as a private library with only tevent_unix.c

This simplifies any new subsystems (or libraries) which need tevent-util
and are linked in both samba and ctdb.

This will allow killing of TCP connections without daemon involvement.

It looks strange that the common code for daemon and helper is in the
server directory.  Having it in the server directory means less
temporary changes to the build configuration.  This code will move
into the helper itself and will no longer be used by the daemon.

1538fc4585 ctdb-tools: Add standalone ctdb_natgw tool script
This is intended to replace the use of "ctdb natgwlist" in 11.natgw
and provide different views of the NAT gateway status.

It replaces the use of CTDB_NATGW_SLAVE_ONLY=yes with a "slave-only"
keyword in the NAT gateway nodes file.  This means the nodes file must
be consistent on all nodes in a NAT gateway group.

Note that this script is not yet integrated, so there are no behaviour
or documentation changes.

951431910d ctdb-recoverd: Add parallel database recovery helper
Parallel database recovery fixes the samba/ctdb deadlock during recovery.

Many times samba tries to grab multiple record locks in sequence.
Consider a case when samba is already holding a record lock on a database
and tries to get a record lock on second database.  If the second record
is not available on the local node, samba asks ctdb to migrate the record.
If recovery occurs at this time (e.g. node becoming inactive), ctdb
cannot freeze all the databases since samba is already holding a lock
and waiting for the second lock.  CTDB can process the second record
request only after the recovery is complete, thus causing a deadlock.

In parallel database recovery, each database is frozen and recovered
independent from each other.  So as soon as the second database is
recovered, CTDB will resend all the pending migration requests and Samba
can get the second lock.  Once samba releases both the locks, ctdb can
freeze the first database and recover it completing recovery process.
