Catch ipw2200 up to equivelancy with v1.0.5

* Fixed #452 problem with setting retry limit (thanks to Hong Liu)
* Fixed #592 race condition during association causing firmware errors
* Fixed #602 problem with building in 64-bit environment
* Fixed #625 problem with SCAN_REQUEST_EXT sometimes failing
* Fixed #645 problem with bit rate not decreasing when moving laptop
  farther from AP
* Fixed #656 problem with 'iwconfig eth1 mode auto' and 'modprobe'
  locking the system
* Fixed #667 problem with "No space for Tx" for hwcrypto=1
* Fixed #685 kernel panic in rmmod caused by led work is still queued
* Fixed #695 problem with network doesn't reassociate after suspend/resume
* Fixed #701 problem with 'iwprvi sw_reset' not resetting the card from
  monitor mode
* Fixed #710 problem with monitor mode being used after a WEP key has
  been configured
* Fixed network->mode vs. priv->ieee->iw_mode checking (thanks to Ben Cahill)
* Fixed "Unknown management packet %d" warning
* Fixed setting channels multiple times in monitor mode causes scan stopped
* Fixed ipw_wx_sw_reset doesn't switch firmware if mode is changed.
* Add duplicate packet checking code (kill ping DUP! and TKIP replay warning)
* Fix hardware encryption (both WEP and AES) doesn't work with fragmentation.
