scsi_mid_low_api.txt updated

The interface between the SCSI mid level and the lower level (HBA) drivers is still a moving target with more changes to come. So instead of a patch against the file currently in Documentation/scsi/scsi_mid_low_api.txt here is a gzipped version:

Please send corrections and suggestions to me.

There are quite a few changes since the last patch (document date on last line was 21st February 2003)
