Support guest writes to the TSC by enabling the "use TSC offsetting"
execution control and writing the difference between the host TSC and
the guest TSC into the TSC offset in the VMCS upon encountering a
write.

Emulate machine check related MSRs to allow guest OSes like Windows to boot.

Don't require <sys/cpuset.h> to be always included before <machine/vmm.h>.

Only a subset of source files that include <machine/vmm.h> need to use the
APIs that require the inclusion of <sys/cpuset.h>.

Advertise the MTRR feature via CPUID and emulate the minimal set of MTRR MSRs.
This is required for booting Windows guests.

Always emulate MSR_PAT on Intel processors and don't rely on PAT save/restore
capability of VT-x. This lets bhyve run nested in older VMware versions that
don't support the PAT save/restore capability.

Note that the actual value programmed by the guest in MSR_PAT is irrelevant
because bhyve sets the 'Ignore PAT' bit in the nested PTE.

Support Intel-specific MSRs that are accessed when booting up a linux in bhyve:
- MSR_PLATFORM_INFO
- MSR_TURBO_RATIO_LIMITx
- MSR_RAPL_POWER_UNIT

Restructure the MSR handling so it is entirely handled by processor-specific
code. There are only a handful of MSRs common between the two so there isn't
too much duplicate functionality.

The VT-x code has the following types of MSRs:

- MSRs that are unconditionally saved/restored on every guest/host context
switch (e.g., MSR_GSBASE).

- MSRs that are restored to guest values on entry to vmx_run() and saved
before returning. This is an optimization for MSRs that are not used in
host kernel context (e.g., MSR_KGSBASE).

- MSRs that are emulated and every access by the guest causes a trap into
the hypervisor (e.g., MSR_IA32_MISC_ENABLE).

- Output a summary of optional VT-x features in dmesg similar to CPU
features. If bootverbose is enabled, a detailed list is provided;
otherwise, a single-line summary is displayed.
- Add read-only sysctls for optional VT-x capabilities used by bhyve
under a new hw.vmm.vmx.cap node. Move a few exiting sysctls that
indicate the presence of optional capabilities under this node.

First cut at porting the kernel portions of 221828 and 221905 from the
BHyVe reference branch to HEAD.

Import of bhyve hypervisor and utilities, part 1.
vmm.ko - kernel module for VT-x, VT-d and hypervisor control
bhyve - user-space sequencer and i/o emulation
vmmctl - dump of hypervisor register state
libvmm - front-end to vmm.ko chardev interface

bhyve was designed and implemented by Neel Natu.
