Martin Schwenke 6fa27bdf18 Eventscripts: 10.interfaces clean-ups - push logic into monitor_interfaces(). 
The logic in the monitor event itself is very complex.  Nearly all of
it can go away by adding a single check of
$CTDB_PARTIALLY_ONLINE_INTERFACES to the return logic of
monitor_interfaces() and reversing the sense of the corresponding
check.

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.
