Pull in some minor bugfixes and functionality enhancements
from CURRENT. These are candidates to be moved to 10.0-release.
r258855
mdoc: quote string properly.
r258673
Don't create an initial value for the host filesystem of "/".
r258668
Allow bhyve and bhyveload to attach to tty devices.
r258614
The 22-bit Data Byte Count (DBC) field of a Physical Region Descriptor was
being read as a 32-bit quantity by the bhyve AHCI driver.
r258609
Fix discrepancy between the IOAPIC ID advertised by firmware tables and the
actual value read by the guest.
r257933
Route the legacy timer interrupt (IRQ0) to pin 2 of the IOAPIC.
r257767
Fix an off-by-one error when iterating over the emulated PCI BARs.
r257729
Add the VM name to the process name with setproctitle().
r257423
Make the virtual ioapic available unconditionally in a bhyve virtual machine.
r257347
Update copyright to include the author of the LPC bridge emulation code.
hand-merge r257018
Tidy usage messages for bhyve and bhyveload.
r256657
Add an option to bhyveload(8) that allows setting a loader environment variable
from the command line.
Discussed with: neel
r256926
Fix AHCI ATAPI emulation when backed with /dev/cd0
- remove assumption that the backing file/device had
512-byte sectors
- fix incorrect iovec size variable that would result
in a buffer overrun when an o/s issued an i/o request
with more s/g elements than the blockif api
r257005
Export the block size capability to guests.
- Use #defines for capability bits
- Export the VTBLK_F_BLK_SIZE capability
- Fix bug in calculating capacity: it is in
512-byte units, not the underlying sector size
This allows virtio-blk to have backing devices
with non 512-byte sector sizes e.g. /dev/cd0, and
4K-block harddrives.

Eliminate unconditional debug printfs.
Linux writes to these nominally read-only registers,
so avoid having bhyve write warning messages to stdout
when the reg writes can be safely ignored. Change the
WPRINTF to DPRINTF which is conditional.
Approved by: re (gjb)
"assignment makes pointer from integer without a cast", by changing the
cmd_lst and rbis members of struct ahci_port from integers to pointers.
Also surround a pow-of-2 test expression with parentheses to clarify it,
and avoid another gcc warning.

This provides ICH8 SATA disk and ATAPI ports, selectable
via the bhyve slot command-line parameter:
SATA
