647b92bf0a MFC 260206: 
Rework the DSDT generation code a bit to generate more accurate info about
LPC devices.  Among other things, the LPC serial ports now appear as
ACPI devices.

Several enhancements to the I/O APIC support in bhyve including:
- Move the I/O APIC device model from userspace into vmm.ko and add
  ioctls to assert and deassert I/O APIC pins.
- Add HPET device emulation including a single timer block with 8 timers.
- Remove the 'vdev' abstraction.

Fix discrepancy between the IOAPIC ID advertised by firmware tables and the
actual value read by the guest.

26b6c9487a Remove obsolete cmd-line options and code associated with 
these.
 The mux-vcpus option may return at some point, given it's utility
in finding bhyve (and FreeBSD) bugs.

70b50f1646 Rename fbsdrun.* -> bhyverun.* 
bhyve is intended to be a generic hypervisor, and not FreeBSD-specific.

(renaming internal routines will come later)

949e126edf Catch up with CURRENTs different timer usage compared to 8.1. A counter 
value of 0 in rategen mode is equivalent to a max initial value.
The TSC is now correctly calibrated on a 9.0 guest.
