- HeapCreate should mask out NT flags and tag allocations with CLASS 1.
- Implemented HeapCreateTagsW, HeapExtend, HeapQueryTagW, HeapSummary, HeapUsage.
- Stubbed RtlUsageHeap, RtlQueryTagHeap, RtlExtendHeap, RtlCreateTagHeap.

- Entirely rewrite Kernel32 Probe functions to um, actually probe (ported Thomas's code in the kernel and adjusted for user-mode and then checked with WINE's code). I can't begin to fathom what the previous routines were supposed to be doing.

- Simplified NtDuplicateObject to a simple stub around ObDuplicateObject, there is no need to have lengthy hacks for NtCurrentProcess/NtCurrentThread().
- Cleanup ObDuplicateObject to use normal Ob routines instead of grovelling through handle table structures and manually touching the handle count: It now calls ObpIncrementHandleCount and all the underlying operations are done on the duplicated handle. Also access state creation is done if the duplicated handle has different desired access.

- Give Files/Devices a parse routine and currently stubplement it for debugging purposes and trying to figure out a way to kill the IopCreateFile hack.
- Implement ObpChargeQuotaForObject. Using a memory breakpoint in WinDBG I've finally found where the OB_FLAG_CREATE_INFO flag gets masked out. Also attempted a very naive quota charging implementation, but it's a guess and probably wrong (but at least it does...something.)

- Call the OkayToClose Procedure, if one is present, to allow the object owner a chance to disallow closing this handle. I believe this is required for properly protecting Winsta/Desktop handles (instead of using the regular protection mode, since that one can be bypassed). Thomas, get to work!

- Added stub exports for ObCloseHandle, ObReferenceSecurityDesciptor, ObSetHandleAttributes, ObSetSecurityObjectByPointer so that someday someone can know what needs to be implemented.
- Removed ObGetObjectPointerCount. It is not exported in newer OSes and was always undocumented.
- Move ObQueryObjecctAuditingByHandle to security.c and optimized it not to attach to the system process, as well as to cache the handle table instead of dereferencing the owner process all the time.

* Implement Per-Processor Lookaside List based allocation and de-allocation of the Object Create Information (object attributes capture) and of the object name. I counted over 4000 allocations for only 30 seconds of runtime, so this change greatly reduces pool fragmentation and increases speed. (Implementation is similar to the IRP lookaside list implementation, but inlined for speed).
* Fix some cases where we weren't freeing captured information properly. This patch should also decrease memory leaks/usage.
* Comment/formatting fixes.

- Re-implement delayed object deletion by using an optimized Object Reaper based on OBJECT_HEADER->NextToFree. Thanks to Thomas for the algorithm.
- Refactor object deletion into two operations: Removal and de-allocation (this is needed for failure during allocation, which we don't do yet).
- BugFixes:
* After freeing an object header structure, also clear the pointer so we don't attempt it again.
* Clear the handle database if there is one
* Make sure the create info flag is set before deleting captured attributes.
* Use the allocation pool tag when de-allocating.
* Use OBJECT_TYPE accounting for tracking the numbef of objects.
* Remove the object from it's typelist if it has creator information.
* Call the security procedure to delete the security descriptor.

- Isolate ObFindObject into CmFindObject for the registry routines. Because of their well-known abuse of Ob, it's better to give them their internal routine so that when/if Ob ever gets fixed to parse properly, it won't force a re-write of Cm's object routines.
