TMPDIR sometimes goes missing during autobuild. When that happens the
error messages produced by CTDB tests are not very helpful. This
should make it clear.

During revoking readonly delegations, if one of the nodes disappears, then
there is no point re-trying revoking readonly delegation. The database
needs to be recovered before the revoke operation can succeed. So retry
only after a grace period.

When ctdb is built in standalone mode, it turned off the python
requirement for submodules by setting Options.options.disable_python
to True before checking for its own (non-optional) python support.
Ad ctdb does not need python for itself or any of the submodules
it is built against, the safest solution seems to be to allow
the python and python-headers checks to not find python.

"ctdb reloadips" use of ipreallocate() can result in a spurious
takeover runs. This can cause a subsequent "ctdb reloadips" to fail
to disable takeover runs (due to there being one already in progress).
There are various possible improvements but a proper fix probably
requires a protocol change. That would mean receiving an ACK for a
takeover run request to indicate that the request will be processes
and then a broadcast to indicate a completed takeover run.
There are various other partial fixes (e.g. de-duping queued takeover
run requests against those in the in-progess queue) and workarounds
(e.g. always do a double ipreallocate() in the tool, which should
absorb the spurious takeover run).
However, this is unlikely to be a real-world problem. Real use cases
should not involve repeatedly reloading the IP configuration.
Instead, work around the problem of flaky tests by manually adding
"ctdb sync" commands to cause extra no-op takeover runs. These should
not add spurious takeover runs and will create synchronisation points
to help avoid the issue.

Some configurations may set CTDB_NFS_CALLOUT to the empty string.
They may do this if they allow a choice of NFS implementations. In
this case the default call-out for Linux kernel NFS should be used.
However, statd-callout does not call nfs_callout_init() to set the
default. Therefore, statd-callout is unable to restart the lock
manager, so the grace period is never entered.
statd-callout must call nfs_callout_init() before trying to restart
the lock manager.
