These have been scattered around the code so that
tevent_loop_allow_nesting() can be called. However, only the main
daemon and some tests currently use nested event loops.
TEVENT_DEPRECATED is already defined in the places where it is needed.

If a record is not on a local node, then it is migrated from remote node.
However, before the client can get a lock on the record, it's possible
for the record to get migrated away. In that case, repeat migration.

Signed-off-by: Amitay Isaacs <amitay@gmail.com>
Reviewed-by: Martin Schwenke <martin@meltin.net>
It does not make sense to update this statistic for the timeout case,
since this could skew the statistic. To keep it simple, just update
it for the usual case where there is lock contention, since this is
the usual case. So the daemon statistic measures time to test the
lock and the corresponding recovery daemon statistic measures time to
take the lock.
Additionally, the recovery daemon will eventually use this code to
take the lock, and the method of updating the latency statistic will
need to be pushed further out to a configurable handler that depends
on the calling context.

Have 0 indicate that the lock was taken. This allows non-zero values
to be used to indicate why the lock could not be taken. EACCES means
lock contention.
For now use just EACCES to cover all failures, since
ctdb_recovery_lock() returns a bool and details of other errors will
be lost. ctdb_recovery_lock() will undergo some big changes, so don't
try to fix this now.

This is unnecessary in Samba >= 4.0 because winbindd monitors IP
address itself and no longer needs to be told when they are dropped.
The smbcontrol commands can hang if a node has recovery mode active
because smbcontrol is unable to connect to the registry. Therefore,
the smbcontrol commands should be removed.

This reverts commit 0ff90f4fac.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=11707
The checks against database generation are not required since
the global generation is updated as part of updating vnnmap
before the actual database recovery. This change was done in
5aab31a39a.
Checking only against the database generation is incomplete. It can
cause CTDB to abort if the following sequence of events happen.
- CTDB gets REQ_DMASTER packet (gen1)
This packet processing gets deferred to get a record lock
- CTDB goes into recovery, marks RECOVERY_ACTIVE
CTDB recovery helper updates vnnmap (gen2)
- CTDB processes REQ_DMASTER packet (gen1)
The check against database generation (gen1) succeeds.
The check for lmaster is now invalid because VNNMAP has changed.
This will cause CTDB to abort due to protocol error.
Reverting the patch stops processing packets of older generation before
they get into call processing.

The "natgwlist" command is no longer marked "auto all" and is also
marked "without daemon". That latter is not strictly true because
ctdb_natgw needs the daemon so a subsequent invocation of "ctdb
nodestatus" will work. However, "without daemon" is used here because
the top-level "ctdb natgwlist" does not need to open a connection to
the daemon. It just needs to invoke ctdb_natgw.
Update tests to suit.
It would make sense to make "ctdb natgw" generally call out to
ctdb_natgw, passing all argument. However, that can be done later.
