Martin Schwenke 9257b57f2c Eventscripts: New configuration variable CTDB_SERVICE_AUTOSTARTSTOP. 
Some of the current auto-start/stop logic is broken, particularly for
Samba.  Fixing it is non-trivial.

If $CTDB_SERVICE_AUTOSTARTSTOP is "yes" then auto-start/stop services
when told to newly manage or no longer manage them.  This defaults to
"yes".

However, if using a canned configuration file that doesn't set
$CTDB_SERVICE_AUTOSTARTSTOP then this stops the auto-start-stop logic
from working.  Therefore, this works around CQ S1026685 - on the
system in question another daemon controls service auto-start/stop and
CTDB just gets in the way.

README 

This directory contains run-time support scripts for CTDB.

Selected highlights:

  ctdb.init

    An initscript for starting ctdbd at boot time.

  events.d/

    Eventscripts.  See events.d/README for more details.

  functions

    Support functions, sourced by eventscripts and other scripts.

  interface_modify.sh

    Script to support add/remove IPs and other funky stuff.  Not sure
    why this is separate... but it certainly allows easy wrapping by
    flock.

  statd-callout

    rpc.statd high-availability callout to support lock migration on
    failover.

Notes:

* All of these scripts are written in POSIX Bourne shell.  Please
  avoid bash-isms, including the use of "local" variables (which are
  not available in POSIX shell).

* Do not use absolute paths for commands.  Unit tests attempt to
  replace many commands with stubs and can not do this if commands are
  specified with absolute paths.  The functions file controls $PATH so
  absolute paths should not be required.
