- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

1. Oops on last commit: note a few SCSI-3 items for data compression page.
2. Change copyright to me- per practive of scsi_sa.c that Justin had
me do a while back.

scsi_sa.h

$Id$ -> $FreeBSD$

Make clear that the DATA COMPRESSION page is a SCSI-3 entity- not a SCSI-2
entity. Add the Device Configuration page data structure- this structure
should be used if you fail to fetch the DATA COMPRESSION page. Make a union
type of a mode header, a device configuration page and the data compression
page.

Add a couple of QIC density defines (QIC 2G/QIC 4GB).

add QIC 525,320,1320,3080 codes

Add structures and function definitions pertinent for hardware locate support.

Add some tape specific density codes- only enough of them here to recognize
some specific older units so we can choose 2FM@EOD or FIXED blocksize
quirks.

SCSI Peripheral drivers for CAM:

da - Direct Access Devices (disks, optical devices, SS disks)
cd - CDROM (or devices that can act like them, WORM, CD-RW, etc)
ch - Medium Changer devices.
sa - Sequential Access Devices (tape drives)
pass - Application pass-thru driver
targ - Target Mode "Processor Target" Emulator
pt - Processor Target Devices (scanners, cpus, etc.)
