Martin Schwenke b7bfe46636 ctdb/eventscripts: Move all eventscript state under $CTDB_VARDIR/state 
Services can be flagged for reconfigure when they release IPs at
shutdown.  The flag is never removed and the service is prematurely
reconfigured during the first "ipreallocated" event, before any IPs
are hosted and before the "startup" event has actually started the
services.

$CTDB_VARDIR/state directly contained the service state subdirectories
and is already removed in the "init" event.  Just push the service
state subdirectories down a level and put everything else in a
subdirectory.

This way all the eventscript state gets cleaned up every time CTDB
starts up.

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.

  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.
