fix wrong function names in softraid RAID1 debug print statements

ok jsing@ as part of a larger diff

No need to rescan chunks in each discipline to find appropriate
volume sector size. Determine volume sector size in sr_meta_init().

Pointed out, tweaked and ok jsing@

Enable creation of softraid volumes using disks with non-512 byte
sectors. Volumes created will present a sector size equal to the
largest sector size of the constituent disks.

sectors. Volumes created will present a sector size equal to the
largest sector size of the constituent disks.

Softraid Metadata version cranks to 6 due to new field.

A few more daddr_t fixes. Rename 'phys_off' variables to 'offset'
since they are now relative to chunks. Use 'blkno' as normal variable
name for daddr_t items rather than mix of 'blkno, blk, offset.

Change field name ssd_data_offset to ssd_data_blkno since it is a
block and not byte quantity.

No intentional functional change.

Remove unneeded #include <disklabel.h>.

Stop adding and subtracting data offset. Just keep to chunk relative
block offsets until actual i/o is constructed and needs the physical
offset. Eliminate a number of <<DEV_BSIZE shifts as a bonus.

remove #include <sys/workq.h>. it wont exist anymore soon.

move arc4random prototype to systm.h. more appropriate for most code
to include that than rdnvar.h. ok deraadt dlg

final removal of daddr64_t. daddr_t has been 64 bit for a long enough
test period; i think 3 years ago the last bugs fell out.

Provide a function that handles the scheduling of work units. This
simplifies the discipline code, avoids code duplication and moves the
scheduling logic into a single location.

ok krw@

Use a state to indicate that a work unit should only be constructed and not
scheduled, rather than trying to imply this from the rebuild flag.

Convert RAID1 to the new work unit completion functions and generic
interrupt handler. Disciplines such as RAID1/4/5/6 need a way to intercept
I/O when the work unit is complete, but before the SCSI xfer is complete.
This is provided via a sd_scsi_wu_done hook, which enables work units to be
restarted or otherwise modified before the SCSI xfer completion occurs.

Use consistent error handling when validating the number of chunks
provided.

More runtime value initialisation functions.

Provide default resource allocation and free functions. Convert all
disciplines except for AOE and CRYPTO, which require custom handlers.

Properly release ccbs when restarting a work unit.

Decouple wakeups on work unit completion from the type of I/O being
performed.

sd_wu_pending is only decremented when scsi_done() or scsi_io_put() are
called. As a result, factor out the the sd_sync check/wakeup code and move
it to after the scsi_done() call in sr_scsi_done().

some that were previously missed).

Rewrite the work unit handling code in the RAID 1/4/5/6 interrupt handlers.
This simplifies the code and will allow for easier conversion to the workq
based work unit completion routines. It also ensures that work units are
always removed from the pending queue and that colliders are started, even
in the event of an I/O failure.
