Changelog from WinPcap 4.1.1

- Bug fixing:
  + Fixed a bug reported by Boaz Brickner (http://pcapdotnet.codeplex.com/):
    the driver could cause an OS crash when an IRP_MJ_CLEANUP is processed
    in parallel with an IRP_MJ_READ/WRITE/DEVICECONTROL. The fix defers the
    deallocation of the open structure in IRP_MJ_CLOSE.
  + Fixed a bug in the buffered write code. A malformed transmit buffer sent
    with pcap_sendqueue_transmit could cause a buffer overflow and crash the
  + Disabled tracing in the driver (it was left on by mistake in the
    previous release of WinPcap).
  + Added the missing export pcap_free_datalinks.
  + Do not show the installation panel with the OS info.
  + Small fix to the documentation regarding WDK.
