OpenBSD complains that malloc.h is deprecated on every gcc invocation.
That hides a lot of real warnings. malloc and friends nowadays are
typically defined in stdlib.h, only check there.
We need memalign. On OpenBSD this does not exist, so libreplace replaces
it. The wscript test in libreplace only checks whether memalign can
link. Unfortunately in glibc memalign comes from malloc.h.

we do DLIST_REMOVE(ev->fd_events, fde); and then
use fde->next in the loop above.
Save off fde->next for loop interation before
this so we can't use a deleted ->next value.

Various scripts (including debug_locks.sh, 00.ctdb, 05.system) need
CTDB_DBDIR to point to the right place... but it doesn't.
Move the rewriting of CTDB_DBDIR to loadconfig() so that it happens
for all scripts. Have this code set internal variable
CTDB_DBDIR_TMPFS_OPTIONS so that ctdbd_wrapper can do the mount.
This loses the generality that was present in dbdir_tmpfs_start() but
it wasn't being used anyway. If it is needed in the future then it
will be in the git history.

We do way too much stuff in the parent smbd in remove_child_pid(). In
particular accessing ctdbd is not a good idea when ctdbd is stuck in something.
We've had a case where smbd exited itself with "ctdb timeout" being set to 60
seconds. ctdb was just stuck doing recoveries, and the parent smbd was sitting
in serverid_exists trying to retrieve a record for a child that had exited. Not
good.
This daemon sits there as parent->cleanupd and receives MSG_SMB_NOTIFY_CLEANUP
messages that hold the serverid and exit status of a former child. The next
commits will step by step empty remove_child_pid in the parent and move the
tasks to the helper.

The recovery daemon pushes knowledge of recovery master election
progress/result to local daemon. It then retrieves that information
again.
Instead, have the recovery daemon reliably track election
progress/result in rec->recmaster so it doesn't need to be retrieved.
Be careful to maintain consistency by only doing this when the local
daemon has been updated.
