Catch ipw2100 up to equivelancy with v1.1.1

* Added WE-18 support.  This allows the use of -Dext with wpa_supplicant
  > 0.4.x (thanks to Hong Liu)
* Fixed #339 problem with iwconfig set/get txpower (thanks to Hong Liu)
* Fixed #598 problem when with error messages when module loaded with
  'disable=1' (thanks to Hong Liu)
* Fixed #640 problem with 'iwlist retry' now showing min/max retry
* Fixed compatibility with wpa_supplicant and the new -Dipw interface
  (that included a fix for 64-bit compatibility)
* Added CFG_CRC_CHECK which allows passing through packets with bad
  CRCs while in monitor mode.
