SAS transport class
PATCH 1/1 SAS transport class
New version of the SAS transport class. This now introduces the concept of remote ports as suggested by James Smart. Also ports can be layer ontop of remote ports in addition to scsi hosts to support extenders, although that functionality is rather theoretical as I didn't manage to update the Fusion driver for that support yet. I've also improved the handling of ports quite a bit, there's a sas_remove_host now that gets rid of all ports and remote ports, and the API to create ports makes much more sense.
There's still quite a few review comments I haven't addresses but I wanted to get a snapshot with support for extenders out.
