Need to be able to recognise a RHEL system. Still use "system" to
start and stop service, since that still works and yields the smallest
change.

This is unnecessary since ctdbd_pid is set very early in the code before
creating any other processes including recovery daemon.

If something unexpectedly uses fork() then an exiting child will
remove the PID file while the main daemon is still running. The real
test is whether the current process has the PID of the main CTDB
daemon, which is the process that calls setsid().
This could be done using getpgrp() instead. At the moment the
eventscript handler harmlessly calls setpgid() - harmless because the
atexit() handlers are cleared upon exec(). However, it is possible
that process groups will be used more in future so it is probably
better to rely on the session ID.
Thanks to Sumit Bose <sbose@redhat.com> for the idea.

Debugging can still be running when a monitor event times out and
scriptstatus output changes.
When debugging a hung script to a log file, write to a temporary file
and move the temporary file over the log file when done. The test
then waits for the log file to appear.

There shouldn't be an early exit for the "init" event. Just make the
"ctdb scriptstatus" call conditional.
While here, move the comment about only running a single instance to
be near locking code. The comment is more useful there.

Check that the $GANRECDIR symlink points to the location specified by
$CTDB_GANESHA_REC_SUBDIR and replace it if incorrect. This handles
reconfiguration and filesystem changes.
While touching this code:
* Create the $GANRECDIR link as a separate step if it doesn't exist.
This means there is only 1 place where the link is created.
* Change some variables names to the style used for local function
variables.
* Remove some "ln failed" error messages. ln failures will be logged
anyway.
* Add -v to various mkdir/rm/ln commands so that these actions are
logged when they actually do something.

About a year ago a check was added to _cluster_is_healthy() to make
sure that node 0 isn't in recovery. This was to avoid unexpected
recoveries causing tests to fail. However, it was misguided because
each test initially calls cluster_is_healthy() and will now fail if an
unexpected recovery occurs.
Instead, have cluster_is_healthy() warn if the cluster is in recovery.
Also:
* Rename wait_until_healthy() to wait_until_ready() because it waits
until both healthy and out of recovery.
* Change the post-recovery sleep in restart_ctdb() to 2 seconds and
add a loop to wait (for 2 seconds at a time) if the cluster is back
in recovery. The logic here is that the re-recovery timeout has
been set to 1 second, so sleeping for just 1 second might race
against the next recovery.
* Use reverse logic in node_has_status() so that it works for "all".
* Tweak wait_until() so that it can handle timeouts with a
recheck-interval specified.
