kernel - Change callout in struct ccb_hdr

* Change the callout declaration in struct ccb_hdr from an embedded
structure to a pointer, add padding to get the whole structure to its
original size (prior to the recent callout patch).

* This removes an improper ABI dependency on the kernel struct callout
structure which was causing 'camcontrol', and 'smartctl' (from
smartmontools) to fail.

Testing: dillon, tuxillo

ahci(4)/sili(4): Fix for drives >2TB.

CAM will issue the 16 byte version of the READ CAPACITY command when
maxsector is 0xffffffff:

----- scsi_da.c -----

kfree(rdcap, M_SCSIDA);
xpt_release_ccb(done_ccb);
xpt_schedule(periph, /*priority*/5);
return;
}
---------------------

However, we are subtracting 1 from it (presumably because it's a "last
sector on the device" value starting at 0) so in CAM, it ended up being
0xfffffffe, resulting in disks attached via ahci(4) and sili(4) to be
limited to 2TB.

To fix, set the local var to 0 in this case, so that after subtracting 1
from the value (cast to 32 bit) CAM gets 0xffffffff.

AHCI/SILI - More adjustments to last commit

* Use the ultradma field instead of the legacy field. All SATA devices
must support DMA so don't bother with the other legacy fields. If the
ultradma field is not initialized (on future devices) then presumably
we do not have to SETXFER at all.

* Note that SATA hard drives do report this field.

AHCI/SILI - Send dummy SETXFER mode even though it is SATA

* If the identify structure contains a non-zero/non-FFFF dmamode field
we send a dummy SETXFER mode command to the device.

* Most SATA DISK devices set this field to 0 or FFFF and in this case no
SETXFER mode command is sent. SETXFER is non-applicable to SATA in
general.

Most ATAPI devices still initialize the dmamode field and some ATAPI
devices still require SETXFER to be sent even though they are native SATA.

SATA->PATA converters may require a SETXFER to be passed through before
the PATA devices will operate properly. In this case the dmamode field
will likely be initialized.

* Add ATA_F_AUTOSENSE and ATA_F_EXCLUSIVE to deal with accessing the
D2H RFIS.

ATA_F_AUTOSENSE tells sili.c that the caller wants to access the rfis.
The sili core is then responsible for copying the rfis out of the LRAM
and into host-memory.

ATA_F_EXCLUSIVE tells sili.c that the caller wants to be the only
command queued to the chip for that particular command.

* Currently ATA_F_AUTOSENSE implies ATA_F_EXCLUSIVE, but ultimately we will
want to do the auto-sense as a separate step so things like ATAPI farms
can run commands in parallel.

This driver was derived from the AHCI driver and retooled extensively
for the Silicon Image chipset. It retains all the cool features from the
AHCI driver including port multiplier (PM) support, NCQ, and hot-plug for
both direct-attached and PM-attached targets.

This initial commit is very alpha and the driver has significant PM-related
bugs. It is not yet ready for prime time.
