3d2b366a36 Go way past 11 and bump bhyve's max vCPUs to 16.
This should be sufficient for 10.0 and will do
until forthcoming work to avoid limitations
in this area is complete.

Thanks to Bela Lubkin at tidalscale for the
headsup on the apic/cpu id/io apic ASL parameters
that are actually hex values and broke when
written as decimal when 11 vCPUs were configured.

8d05d984e8 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.

9c2aecf6da 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.

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

(renaming internal routines will come later)

d45d8a8d66 - Add in an XSDT to stop acpidump from exiting with a
'XSDT corrupted' error
- Fix up OEMID/OEM Table ID string padding in the DSDT.

Output on a verbose boot now looks like

6f600a733a ACPI support for bhyve.
The -A option will create the minimal set of required ACPI tables in
guest memory. Since ACPI mandates an IOAPIC, the -I option must also
be used.

Template ASL files are created, and then passed to the iasl compiler
to generate AML files. These are then loaded into guest physical mem.

In support of this, the ACPI PM timer is implemented, in 32-bit mode.

Tested on 7.4/8.*/9.*/10-CURRENT.
