If the cluster is partitioned then nodes in one partition can not take
the lock anyway, so election is pointless. It just introduces
unnecessary corner cases.
Instead just race for the lock.
When a node notices a lack of leader and notifies other nodes of an
election via an unknown leader broadcast, the cluster lock election is
hooked into this broadcast.
The test needs to be updated because losing the cluster lock can now
result in a leadership change.

This has support for log rotation (or re-opening).
The log format is updated to use an RFC5424 timestamp and to include a
hostname. The addition of the hostname allows trivial merging of log
files from multiple cluster nodes.
The hostname is faked from the CTDB_BASE environment variable during
testing, as per the comment in the code. It is currently faked in a
similar manner in local_daemons.sh when printing logs, so drop this.
Unit tests need updating because stderr logging no longer produces a
"PROGNAME[PID]: " header.

RFC5952 says the existing style is not recommended and the [] style
should be employed.
There are more optimised ways of adding the square brackets but they
tend to be uglier.
Parsing IPv6 sockets without [] is now tested indirectly by parsing
examples in both styles and comparing the results.

Fedora 34 now has a shell function for the which command, which causes
these uses of which to return the enclosing function definition rather
than the executable file as expected.
The event script unit tests always expect the stub service command to
be used, so the conditional in these functions is unnecessary.
$CTDB_HELPER_BINDIR already conveniently points to the stub directory,
so use it here.

If a script times out the caller can talloc_free() the script_list
output of run_event_recv, which talloc_free's proc->output from
run_proc.c as well. If the script generates further output after the
timeout and then exits after a while, the SIGCHLD handler in the
eventd tries to read into proc->output, which was already free'ed.
Fix this by not doing just a talloc_steal but a talloc_move. This way
proc_read_handler() called from run_proc_signal_handler() does not try
to realloc the stale reference to proc->output but gets a NULL
reference.
I don't really know how to do a knownfail in ctdb, so this commit
actually activates catching the signal by waiting long enough for
22.bar to exit and generate the SIGCHLD.

*** TEST COMPLETED (RC=1) AT 2021-02-02 06:18:48, CLEANING UP...
This should never happen. If this really fails then the wait should
time out.
The problem is that wait_until() does:
"$@" || _rc=$?
and vacuum_test_key_dmaster() currently calls ctdb_test_fail() on
failure, which causes the shell to exit. Instead, pass a variant to
wait_until() that simply returns the correct status instead of
exiting.
An alternative would be to change the statement in wait_until() to do:
("$@") || _rc=$?
so it captures the exit. However, this is a global change and
requires more thought.
