Catch ipw2200 up to equivelancy with v1.0.3

* Fix #616 problem with OOPS on module load (thanks to Yi Zhu)
* Fixed problem with led module parameter being described as
  'auto_create'
* Added support to merge between adhoc networks (thanks to Mohamed Abbas)
* Added semaphore lock at the driver's entry points to protect against
  re-entry (thanks to Mohamed Abbas)
* Added semaphore lock to background scheduled driver actions (thanks to
  Mohamed Abbas)
* Changed how signal quality is reported for scan output (thanks to
  Peter Jones)
* Fixed how high/low clamp values of signal quality are reported so a
  more consistent ramp is provided (thanks to Bill Moss)
* Fix #624 problem with duplicate addresses (again)  (thanks to Bernard
  Blackham)
* Fix #385 problem with fragmentation and certain sized packets (thanks
  to Mohamed Abbas)
* Modified iwconfig network name if RF kill is enabled to say 'radio off'
