- Implemented ScsiPortCompleteRequest.

Browse source 
- Fixed the calculation of the max transfer size.
- Rewrote parts of SpiScanAdapter and SpiSendInquiry to speed up device detection.
- Fixed the handling of sense info data for HBA's which are auto request sense capability.
- Added some more debug messages.
