Major update and bugfix for the 'mly' driver.
- Convert to a more efficient queueing implementation. - Don't allocate command buffers on the fly; simply work from a static pool. - Add a control device interface, for later use. - Handle controller overload better as a consequence of the improved queue implementation. - Add support for the XPT_GET_TRAN_SETTINGS ccb, and correctly set the virtual SCSI channels up for multiple outstanding I/Os. - Update copyrights for 2001. - Some whitespace fixes to improve readability. Due to a misunderstanding on my part, previous versions of the driver were limited to a single outstanding I/O per virtual drive. Needless to say, this update improves performance substantially.
