Catch bhyve up to CURRENT.
Lightly tested with FreeBSD i386/amd64, Linux i386/amd64, and
OpenBSD/amd64. Still resolving an issue with OpenBSD/i386.

265941,265951,266390,266550,266910:
Various bhyve fixes:
- Don't save host's return address in 'struct vmxctx'.
- Permit non-32-bit accesses to local APIC registers.
- Factor out common ioport handler code.
- Use calloc() in favor of malloc + memset.
- Change the vlapic timer frequency to be in the ballpark of contemporary
hardware.
- Allow the guest to read the TSC via MSR 0x10.
- A VMCS is always inactive when it exits the vmx_run() loop. Remove
redundant code and the misleading comment that suggest otherwise.
- Ignore writes to microcode update MSR. This MSR is accessed by RHEL7
guest.
Add KTR tracepoints to annotate wrmsr and rdmsr VM exits.
- Provide an alias for the userboot console and name it 'comconsole'.
- Use EV_ADD to create an mevent and EV_ENABLE to enable it.
- abort(3) the process in response to a VMEXIT_ABORT.
- Don't include the guest memory segments in the bhyve(8) process core dump.
- Make the vmx asm code dtrace-fbt-friendly.
- Allow vmx_getdesc() and vmx_setdesc() to be called for a vcpu that is in
the VCPU_RUNNING state.
- Enable VMX in the IA32_FEATURE_CONTROL MSR if it not enabled and the MSR
isn't locked.

Expand the support for PCI INTx interrupts including providing interrupt
routing information for INTx interrupts to I/O APIC pins and enabling
INTx interrupts in the virtio and AHCI backends.

Various AHCI fixes:
- Fix issue with stale fields from a recycled request pulled off the
freelist.
- Provide an indication a "PIO Setup Device to Host FIS" occurred while
executing the IDENTIFY DEVICE and IDENTIFY PACKET DEVICE commands.
- Provide an indication a "D2H Register FIS" occurred during a SET FEATURES
command.
- Though there currently isn't a way to insert new media into an ATAPI
drive, at least pretend to support Asynchronous Notification (AN) to
avoid a guest needlessly polling for it.
- Don't reissue in-flight commands.
- Constrain the amount of data returned to what is actually available
not the size of the buffer.

r257933,r258609,r258614,r258668,r258673,r258855
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.

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.

"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

ATAPI
-s <slot>,ahci-cd,<image-file>
