- Fix KiDispatchException to unmask KI_EXCEPTION_INTERNAL when setting the exception code, so that usermode/SEH filters get proper exception codes again.
- Fixes and compatible merges from KD Branch:
 - Add stubs for KdSave, KdRestore, KdDebuggerInitialize0, KdSendPacket, KdReceivePacket to kdcom.dll
 - Implement and export KeTryToAcquireSpinLockAtDpcLevel.
 - Add EXCEPTION_RECORD64 and LIST_ENTRY64, KeTryToAcquireSpinLockAtDpcLevel, BREAKPOINT_COMMAND_STRING, Ke386SetCr2, Ke386SetDr3, Ke386SetDr6.
 - Remove non-kernel routines from kdfuncs.h and remove deprecated routines from ke.h.
 - Implement KiRestoreProcessorControlState, KeFreezeExecution, KeThawExecution, ExAcquireTimeRefreshLock, ExReleaseTimeRefreshLock.
 - Rename ModuleLoadList to PsLoadedModuleList. Add PsNtosImageBase and set value in it.
 - Add skeleton wdbgexts.h with what's needed until now, this is a PSDK header.
 - Add kddll.h for KDCOM/1394/USB2.DLL prototypes.
 - Add windbgkd.h with KD protocol definitions. Used to be an NT5 DDK header, but was removed, so this goes into include\reactos.
 - Fix KiDebugService to load EDX from KTRAP_FRAME_EDX, not KTRAP_FRAME_EAX!.
 - Fix CommonDispatchException to check for the argument count in ECX, not EAX. Previously we were ignoring parameter counts and never filling out exception records!
 - Add KdDebuggerInitialize1 and enable call to it.
 - Fix KD_SYMBOLS_INFO definition and DbgLoadImageSymbols prototype.
 - Implement DbgUnLoadImageSymbols.
 - Fix some small bugs in KeBugCheckWithTf and add various debugger calls/checks where needed.
 - Fix bugcheck recursion code which was incorrect.
 - Only save/restore CR4 if KeFeatureBits indicates CR4 support exists.
 - Export KdDebuggerNotPresent since KDCOM needs it.
 - Add KCONTINUE_STATUS.
 - Add DBGKD_ANY_CONTROL_SET and X86/IA64/AMD64 control sets.
 - Add DBGKD_MANIPULATE_STATE64 and all sub-structures (READ_MEMORY, WRITE_MEMORY, etc).
 - Create GCC_ULONG64 type to hack around a bug in GCC which is incapable of creating entries for externals at compile-time for 64-bit pointers.
 - Rename NameSpaceRoot to ObpRootDirectoryObject, IopLogListHead to IopErrorLogListHead, BugcheckCallbackListHead to KeBugcheckCallbackListHead, BugcheckReasonCallbackListHead to KeBugcheckReasonCallbackListHead, ObTypeObjectType to ObpTypeObjectType.
 - Create ntverp.h and common.ver files. These are the standard files used by the NT/DDK build systems and we should try to support them as well instead of re-defining everything our own way (especially if we want to build ddk-compatible drivers later on).
 - Made init.c use version data from ntverp.h instead of hard-coding.
 - Defined NT 5.2.3790.1830 as the version we report.
 - Fixed up .rc file to be correct and match DDK-sytnax/style.
 - For now only the kernel uses this new versionning scheme, but we should change the build system later to use this for every component.
 - Fix KiSaveProcessorControlState and KiRestoreProcessorControlSate. The latter doesn't freeze the CPU anymore so it's enabled, and the former doesn't cause WinDBG to panic anymore and display weird data.
 - KPROCESSOR_STATE is not 4-byte aligned.
 - Use DR_MASK and DR7_OVERRIDE_V in KiUpdateDr7, KiRecordDr7 instead of DR_ACTIVE_MASK.
 - Add ExceptionRecord32To64.
 - Fix generation of driver name for symbol load.
