Martin Schwenke bc5f0a2b65 ctdbd: Remove command-line option --debug-hung-script 
Use an environment variable instead.  This just means that the
initscript exports CTDB_DEBUG_HUNG_SCRIPT and the code checks for the
environment variable.

The justification for this simplification is that more debug options
will be arriving soon and we want to handle them consistently without
needing to add a command-line option for each.  So, the convention
will be to use an environment variable for each debug option.

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.
