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

VMM: GIM raw-mode support.

VMM: Some more internal decls.

VMM: Make the thread-context hook functions VMM internal linkage.

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

doxygen fixes.

PDMCritSect: Ditto VERR_INTERRUPTED fix for shared critical sections.

Change implementation for turning a reset into a power off to prevent the VM from executing while the power down thread is not running

VMM: Propagate errors properly while leaving HM context.

VMM: Ensure longjmps after hmR0[Vmx|Svm]LeaveSession() don't happen.

VMM/VMMR0: Preemption hooks implemented and enabled for Solaris and Linux hosts.

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

VMM: RTThreadCtxHooksAre[Registered|Created](). Moved it into IN_RING0 as soon we'll require PFNRTTHREADCTXHOOK.

VMM/VMMR0,GVMMR0: Thread-context hooks creation/release. The registeration/de-registeration and HM hook implementation is still todo.

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.

VBOX_WITH_RAW_MODE changes.

PGMCritSectRw: Prep for ring-0 and raw-mode context operation.

Alignment.

VMM/VMMR0: HM old-code segregation.

+VMMR3GetCpuByIdU, -FNATOMICHANDLER

VMM/VMMR0: Camel case.

VMM: HM cleanup.

VMM: HM cleanup.

VMM: Must flush changes pending in the handy page array before freeing memory. There may be requests to free shared pages in there, esp. in a guest shutdown scenario.

hrpmf. not needed.

SUPDrv,VMM: Tracepoints in raw-mode.

STAM,GMM,VBoxDbg: Adding GMM statistics (at last). Introduces STAMTYPE_BOOL and STAMTYPE_BOOL_RESET. Fixes a beyond end of string access in VBoxDbg (memcmp).

VMM: Detect recursive rendezvous calls. Removed the unused API VMMR3AtomicExecuteHandler.

IOM,PDMCritSect: Extended PDMCritSectEnter to handle rcBusy=VINF_SUCCESS as a request to call ring-3 to acquire a busy lock. Implemented device level locking in the MMIO code.

VMM: Sketched out where to do the initial I/O MMU setup. This adds a VMINITCOMPLETED_HWACCM and makes HWACCMR3InitFinalizeR0 private (invoked from HWACCMR3InitCompleted(,_RING0).

VMM,Main: Added VMM thread init and term notifications so that Main can make sure COM is uninitialized. (Maybe we should just say IPRT cleans up COM?)

PCI: start of driver communication infrastructure

fix OSE
