VMM/GIM: nits.

VMM/GIM: cleanup.

VMM/GIM: nits.

VMM/MSRs: Added status codes for returning to ring-3 to service the MSR access.

wrong again

GIM nits: Must check version and config when loading saved state. Saved state version macros shouldn't be called guest-interface-manager-saved-state-manager-version, but rather guest-interface-manager-saved-state-version. SSM failures are sticky, so no need for AssertRCReturn for every SSM call, only when we want to use the data. First sentence of function documentation provide a brief description of the function and for readability purposes stand alone (also, keep it short when possible).

VMM/GIM: Fix initialization of Hyper-V bits that rely on HM initialization to be completed.

VMM/GIM: Add Hyper-V SSM version to the saved-state.

Comments and nits.

VMM: VT-x and AMD-V support for making GIM hypercalls.

VMM/GIM, VMM/HM: Add support for Hyper-V hypervisor capabilities reporting through CPUID. Updated saved states as well, will break old states.

VMM/GIM: Fix Hyper-V TSC offset scaling to 100ns units.

VMM/GIM: Fixes to saved state, enabled reset MSR availability in CPUID.

VMM/GIM: Bits, try to find out why it breaks on mac2-rel.

VMM/GIM: More bits for Hyper-V implementation.

VMM/GIM: bits.

VMM/GIM: Mapping of GIM MMIO2 regions and Hyper-V provider work.

VMM/GIM: Hyper-V provider, work-in-progress.

VMM/GIM: Hyper-V provider, work-in-progress.

GIM: Skeleton, work in progress.
