- Stub ExReferenceCallBackBlock and ExDereferenceCallBackBlock until I get the locking right.
- These callbacks are used by Cm as well as Ps inside Windows NT and combine the power of PushLocks, Rundown Protection and Fast Referencing to ensure callbacks only get called once and thread safely. Not yet used in ROS.

- Make code use standard NT structures.
- Fix object type initialization.
- Fix calls to ExCreatecallback during system initalization which were randomly overwriting memory.
- Fix ExREgisterCallback which was allocating only a pointer inside of the entire structure, also over-writing system memory.

- Re-identize some APC code (just formatting change).
- Detect APC during GateWait. Previous check scanned for DeferredReady, which is incorrect.
- Simplfy KeremovequeueApc to take advantage of the fact RemoveEntryList now returns whether the list is empty or not.

- pixel bits must be pre-multiplied with the alpha channel
- along with the previous LookupIconIdFromDirectoryEx, basic alpha blending is working. some bugfixing is still required.

- The rundown event is a sync event, not a notification event.
- Only take slow path when waiting for release if the value changed *and* is still not active, not if only one of the two is true.

[4 bug fixes]:
- Setup default GrantedAccess for system init thread/process in ObInit.
- Fix a small bug in ObpReapObject.
- Set object header flag is deletion was done deferred.
- Simplify ObpDeferObjectDeletion.
- Use KeAreAllApcsDisabled instead of only checking IRQL to determine if we should do defered deletion.
svn path=/trunk/; revision=25471
- Isolate FuckedUpCm version of ObpLookupDirectoryObject into CmpLookupDirectoryObject to avoid name info leak.
- Rename ObpIncrementQueryReference to ObpAcquireNameInformation and ObpDecrementQueryReference to ObpReleaseNameInformation and make some changes to make calling a lot easier.
- Fixup reference increment loop in above function.
- Fix incorrect check for defer delete flag instead of query references flag.
- Only clear the directory/directory lock flag in ObpCleanupDirectoryLookup if the directory was actually locked.
- Fix lock logic in ObpLookupDirectoryEntry.
- Properly handle the case when lookup occurs after an existing object, avoid name information leak and reference leak.
- Hold shared lock inside NtQuerydirectoryObject.
- Properly initiailize the directory object in NtCreateDirectoryObject.
- Clear create info before creating the unnamed handle in ObInsertObject.
- Only dereference the target process if we actually have one in NtDuplicateObject.
- Don't double-reference the name information in ObpDeleteNameCheck, thus avoiding another leak.
- Fix object case sensitivity check in ObpLookupObjectName.

- ObpReferenceProcessObjectByHandle is always called with HandleInformation, remove this check.
- ObpReferenceProcessObjectByHandle already gets a process parameter, don't query the current one.
- ObpReferenceProcessObjectByHandle already gets a handle table, don't query the current one.
- ObpDecrementHandleCount shouldn't remove the object from the creator info.
- ObpDecrementHandleCount should clear the exclusive process if this is the last handle.
- Killing a protected handle should raise an exception if a debug port is connected, not an exception port.
- ObpIncrementHandleCount should support OBJ_FORCE_ACCESS_CHECK.
- ObpIncrementHandleCount needs to support ObDuplicateHandle.
- ObpIncrementHandleCount needs to support being called without an AccessState.
- Fix interlocked handle count accounting.
- Allow user-mode to create kernel-mode handles.
- Fix the way Additional reference bias is de-referenced during failures.
- Complete rundown in ObKillProcess.
- Send SourceProcess in ObDuplicateHandle.
- Assume initial failure and clear handle in ObDuplicateHandle.
- Don't leak object table references when failing in ObDuplicateHandle.
- Assume failure in ObOpenObjectByName.
- Don't leak buffer during failure in ObOpenObjectByName.
- Don't leak object reference durning failure in ObOpenObjecByName.
- Validate handle attributes in ObOpenObjectByPointer.
- Use RtlCopyMemory when possible to speed up.

- Fix LPC process closing bug.
- Rewrite executive timer support to make it thread-safe and use proper locking order and semantics as well as safe referencing. Also implement Windows 2003 feature of flushing DPCs when a timer is deleted, to avoid the timer from being fired after deletion.

- sysreg is now able to start the emulator but it cannot get any debug data yet. But this might be due that i tested sysreg in linux under vmware which then ran qemu....

- Yeah, this adds another regression on top of the new Ob stuff, but in the end it's for the better, as it removes more race conditions and buggy code.
- This whole week I've fixed about 45 bugs and removed a dozen race conditions, sorry for the 2-3 regressions, they will be fixed ASAP.
- DELETE MAKEFILE.AUTO BEFORE BUILDING THIS BUILD.
svn path=/trunk/; revision=25411
- Implement ObpReferenceProcessObjectByHandle and simplfy ObDuplicateObject.
- Disable hard errors while closing handles, and protect against races. Also print our error message since it seems handles aren't being closed now (message displays leak count).
- Honour DUPLICATE_CLOSE_SOURCE during failure paths in ObDuplicateObject, and catch race conditions.
- Add some more sanity checks and speed up some internal referencing.
svn path=/trunk/; revision=25408
- Add calls to ObpInitializeDirectoryLookup where required.
- Fixup calls to ObpAcquireDirectoryLockExclusive, but still keep them stubbed out for now.
