    cam: Update scsi_all.h to reflect 30 years of evolution
    
    scsi_all.h started out life as a work by Julian Elischer to add SCSI
    support to CMU Mach 2.5. It was 373 lines. Julian ported this to 386BSD,
    included in the 386BSD patch kit and incorported into FreeBSD at its
    creation. Justin used this file when writing CAM, and imported it with
    the initial CAM import, but only 30% (100 lines) of the original
    remained. Justin moved from bitfields to bytes in structures, dropped
    the complex unions, and renamed many structures to have their length
    appended. Only about 30 structure names and about 40 #defines remained
    from the original. The define names were taken directly from the SCSI
    standard with spaces replaced by '_', so had no creativity. Apart from
    the license comment, there were no comments retained (all the comments
    in the CAM import were written by Justin and Ken). Even at that time,
    Justin and Ken could have put their copyrights and names and moved to an
    acknowledgement of Julian.
    
    In the almost 30 years since that original import, this file has grown
    to 4500 lines.  Kenneth Merry, Alexander Motin and Justin Gibbs write
    85% of the file's lines, if mechanical commits are omitted. Other
    contributors contributed less than %5 each of the file.
    
    Replace the original license (which lacked a copyright even and has been
    criticized as ambiguous) with FreeBSD's standard 2-clause license. Add
    copyrights for Justin, Ken and Alexander, with the date ranges they
    contributed to the file. Add a note about the origin of the file to
    acknowledge Julian's original work upon which all this was built, though
    it's become a ship of Theseus in the mean time, built and rebuild many
    times.
    
    On an absolute scale, there's less than 1% of the current file with
    lines from the original, and those are named after the names in the SCSI
    standards and likely wouldn't qualify for copyright protection.
