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

VMM: GIM raw-mode support.

CPUMCTXCORE elimination.

CPUMCTXCORE elimination.

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

tstVMM: Extended it with a 'msr' mode for dump the MSRs of the host CPU brute-force style.

VMM: Minor nit, coding style.

No COM port usage by default, except on double faults.

I/O breakpoints for raw-mode and non-string instructions in IEM.

VMM: More debugging related stuff.

VMM: Debug register handling redo. (only partly tested on AMD-V so far.)

VMM, recompiler: Purge deprecated macros.

- *: Where possible, drop the #ifdef VBOX_WITH_RAW_RING1 when EMIsRawRing1Enabled is used. - SELM: Don't shadow TSS.esp1/ss1 unless ring-1 compression is enabled (also fixed a log statement there). - SELM: selmGuestToShadowDesc should not push ring-1 selectors into ring-2 unless EMIsRawRing1Enabled() holds true. - REM: Don't set CPU_INTERRUPT_EXTERNAL_EXIT in helper_ltr() for now.

IOM: Adding pVCpu to a lot of calls and moving the lookup caches from VM to VMCPU.

Ring-1 compression patches, courtesy of trivirt AG: - main: diff to remove the hwvirt requirement for QNX - rem: diff for dealing with raw ring 0/1 selectors and general changes to allowed guest execution states - vmm: changes for using the guest's TSS selector index as our hypervisor TSS selector (makes str safe) (VBOX_WITH_SAFE_STR ) - vmm: changes for dealing with guest ring 1 code (VBOX_WITH_RAW_RING1) - vmm: change to emulate smsw in RC/R0 (QNX uses this old style instruction a lot so going to qemu for emulation is very expensive) - vmm: change (hack) to kick out patm virtual handlers in case they conflict with guest GDT/TSS write monitors; we should allow multiple handlers per page, but that change would be rather invasive

PATM: Changed two Main APIs to use PUVM instead of PVM (one of them directly accessed it). Lot's of function scope cleanups.

EM,TRPM: VINF_SELM_SYNC_GDT fixes.

TRPM: Logging changes.

trpmGCExitTrap: Check for VMCPU_FF_SELM_SYNC_GDT, VMCPU_FF_SELM_SYNC_LDT and VMCPU_FF_SELM_SYNC_TSS if rc is VINF_SUCCESS and return with VINF_SELM_SYNC_GDT to ring-3. Seen when cr4.VME is changed and a trap is forwarded shortly afterwards. The FF remains set and causes TRPM to assert in the forwarding code (debug only).

SELM,DIS,CPUM,EM: Hidden selector register cleanups.

VMM: Avoid stale selector issues in RC so there will be no need to try fix them by recursive trapping (this was broken for GS since forever anyways).

CPUMRaw[SG]etEFlags: Drop pCtxCore.

CPUMGetGuestCPL: Drop the context core pointer and use the Guest state in CPUMCPU via pVCpu.

CPUM: Combined the visible and hidden selector register data into one structure. Preparing for lazily resolving+caching of hidden registers in raw-mode.

Avoid using SELMValidateAndConvertCSAddr+EMInterpretDisasOneEx when possible and call EMInterpretDisasOne instead. Changed EMInterpretDisasOne to use SELMValidateAndConvertCSAddr instead of SELMToFlatEx.
