VMM: renamed HM_[DISABLE|RESTORE]_PREEMPT_IF_NEEDED() macro.

HMR0VMX,EM,IEM: Moved the CRx related interpretation methods from EM to IEM (VT-x only) to avoid tinkering with the EMAll.cpp stuff any more.

VMM/GIM: Allow dynamic enabling of #UD traps and per-VCPU hypercalls.

VMM: GIM raw-mode support.

HM: Determine VT-x, AMD-V, nested paging and unhindered guest execution support+config earlier so CPUM can make decisions based on it.

VMM: VMMR0ThreadCtxHooksDeregister returns void, further simplified HM_[DISABLE|RESTORE]_PREEMPT_IF_NEEDED() a bit.

VMM: Clear idHostCpu mapping while deregistering the context-hooks rather than in HMR0Leave(). Simplified HMR0_[DISABLE|RESTORE]_PREEMPT_IF_NEEDED() and made VMMR0ThreadCtxHooksDeregister() check before deregistering the hook rather than asking the caller to do it each time.

doxygen fixes.

VMM: Fix restoring 32-bit guest FPU state on 64-bit capable VMs.

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

Function no longer there.

VMM/HM: Use unordered ASM atomics for safely updating HM flags.

VMMR0/HMR0: HM-Context flag macros.

VMM/HM: Added total VM-exits STAM.

HM: Operative macros for HM-context flags.

VMM: Enable thread-context hooks. Reimplemented event injection logic for VT-x and AMD-V.

VMM/HM: Preemption hooks, work in progress. Hopefully I didn't break the non-hook case.

VMM/HM: Preemption hooks. Some common structural changes and cleanup, and initial imlementation of VT-x/AMD-V specific hook functionality.. Work in progress.

HM.cpp: Added APIs for checking whether VT-x and AMD-V are enabled.

EM: Started on HM single stepping for IEM verification purposes. Trying to fix the HM debugging in the proccess. VT-x only atm.

VMM: Started HMSVMR0 work. Unify the AMD-V erratum 170 verification code between R0 and R3. General HM tidying.

Main, VMM: Added an API seting to disable VT-x unrestricted execution.

Move HMRCA.asm into the switcher code so we don't need VMMRC.rc.

HMIsInHwVirtNoLongJmpCtx

VMM: Introduced VMCPUSTATE_STARTED_HM for indicating that we're between HMR3Enter and HMR3Leave. Added HMIsInHwVirtCtx and VMMIsLongJumpArmed methods/macros.

VMM: SELM and VMM early HM init changes.

Do HMR3Init first in vmR3InitRing3 so the other components can skip raw-mode bits during init.

HM,++: pVM -> pUVM for main, mark as many as possible interfaces module internal.

VMM/VMMAll, VMMR3: forceflags for updating CR3 and PAE PDPEs.

VMM: HM cleanup.
