Emulate MSR 0xC0011024 when running on AMD processors.

OpenBSD guests test bit 0 of this MSR to detect whether the workaround for
erratum 721 has been applied.

Merge projects/bhyve_svm into HEAD.

After this change bhyve supports AMD processors with the SVM/AMD-V hardware
extensions.

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).

Ignore writes to microcode update MSR. This MSR is accessed by RHEL7 guest.
Add KTR tracepoints to annotate wrmsr and rdmsr VM exits.

Add an option to ignore accesses by the guest to unimplemented MSRs.

Also, ignore a couple of SandyBridge uncore PMC MSRs that Centos 6.4 writes
to during boot.

'bhyve' was developed by grehan@ and myself at NetApp (thanks!).

Add an explicit exit code 'SPINUP_AP' to tell the controlling process that an
AP needs to be activated by spinning up an execution context for it.

The local apic emulation is now completely done in the hypervisor and it will
detect writes to the ICR_LO register that try to bring up the AP. In response
to such writes it will return to userspace with an exit code of SPINUP_AP.

First cut to port bhyve, vmmctl, and libvmmapi 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.
