This adds a generic infrastructure to register scripts which will
be called when the delete_ip_from_iface() funtion needs to readd
secondary ips to an interface.

to control whether or not to check if we are swapping, and produce
useful output into the logfile if we are.
For production systems with dedicated nas-heads we should never swap.
But for developer/test systems we often use smaller nondedicated systems where
we can no longer guarantee that we will not be using swap.
(This used to be ctdb commit db87849bf3380914a63a626412bec209dbea7d20)
We should never enter swap; if we do, show the memory state of the machine and the process list. This will help us diagnose what caused the condition before it's too late and the box starts OOM-killing processes.

If "$1" was empty than loadconfig would load the ctdb config twice.
This stops that from happening.

Proper fix for 085d1bea78fabf754ef6dd6d323f74a1d361e45c's workaround.
$NFS_TICKLE_SHARED_DIRECTORY was being used before it is set via
loadconfig.
Ronnie actually spotted this one. :-)

This puts single quotes around everything and uses eval on the
command-lines that actually start ctdbd. The eval causes the single
quotes to be interpreted.
The "redhat" init style no longer uses the Red Hat daemon function.
It loses the quoting and re-splits on spaces. Instead we add an extra
line that uses the success/failure functions to keep things pretty.
Note that this means that we don't respect daemon's
$DAEMON_COREFILE_LIMIT variable but we do our own core file handling
with $CTDB_SUPPRESS_COREFILE anyway. daemon's core file handling was
probably overriding what we were doing anyway, so this can be regarded
as a bug fix.

All other scripts do 'loadconfig ctdb' before any other 'loadconfig foo'
call. I think we should do the same in statd-callout.
Otherwise it's very confusing, if you have configured some Options
in /etc/sysconfig/ctdb, but /etc/ctdb/statd-callout doesn't notice
them.

when checking link status for an interface, first
check if this interface is in fact a bond device
(by the precense of a /proc/net/bonding/IFACE file)
and use that file for checking status.
Othervise assume ib* is an infiniband interface which we donnt know how
to check, or otherwise it is an ethernet interface and ethtool should
hopefully work.

The functions file no longer causes a side-effect by doing a shift.
It also doesn't set a convenience variable for $1.
All eventscripts now explicitly use "$1" in their case statement, as
does the initscript. The absence of a shift means that the
takeip/releaseip events now explicitly reference $2-$4 rather than
$1-$3.
New function ctdb_standard_event_handler handles the status and
setstatus events, and exits for either of those events. It is called
via a default case in each eventscript, replacing an explicit status
case where applicable.
