3d5444c864 Add emulation for legacy x86 task switching mechanism.
FreeBSD/i386 uses task switching to handle double fault exceptions and this
change enables that to work.

af5bfc53b8 Add SMBIOS support.
A new option, -U, can be used to set the UUID in the System
Information (Type 1) structure.  Manpage fix to follow.

062b878f58 Changes required for OpenBSD/amd64:
- Allow a hostbridge to be created with AMD as a vendor.
  This passes the OpenBSD check to allow the use of MSI
  on a PCI bus.
- Enable the i/o interrupt section of the mptable, and
  populate it with unity ISA mappings. This allows the
  'legacy' IRQ mappings of the PCI serial port to be
  set up. Delete unused print routine that was obscuring code.
- Use the '-W' option to enable virtio single-vector MSI
  rather than an environment variable. Update the virtio
  net/block drivers to query this flag when setting up
  interrupts.: bhyverun.c
- Fix the arithmetic used to derive the century byte in
  RTC CMOS, as well as encoding it in BCD.

49cc03da31 Add a new capability, VM_CAP_ENABLE_INVPCID, that can be enabled to expose
'invpcid' instruction to the guest. Currently bhyve will try to enable this
capability unconditionally if it is available.

Consolidate code in bhyve to set the capabilities so it is no longer
duplicated in BSP and AP bringup.

Add a sysctl 'vm.pmap.invpcid_works' to display whether the 'invpcid'
instruction is available.

94c3b3bffc 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.

b060ba5024 Simplify the assignment of memory to virtual machines by requiring a single
command line option "-m <memsize in MB>" to specify the memory size.

Prior to this change the user needed to explicitly specify the amount of
memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>).

The "-M" option is no longer supported by 'bhyveload' and 'bhyve'.

The start of the PCI hole is fixed at 3GB and cannot be directly changed
using command line options. However it is still possible to change this in
special circumstances via the 'vm_set_lowmem_limit()' API provided by
libvmmapi.

91039bb268 Specify the length of the mapping requested from 'paddr_guest2host()'.
This seems prudent to do in its own right but it also opens up the possibility
of not having to mmap the entire guest address space in the 'bhyve' process
context.

e285ef8d28 Rename fbsdrun.* -> bhyverun.*
bhyve is intended to be a generic hypervisor, and not FreeBSD-specific.

(renaming internal routines will come later)
