[RDBSS]
[RXCE]
[DDK]
Add an initial implementation of the RXCE and RDBSS libraries that are used to implement mini-redirectors
The associated headers are also added to DDK
The implementation is partial (really!) and is only working for read-only operations.
It leaks memory as hell (no refcounting implemented) and thus, objects freeing is not implemented.
It was tested with NFS41 driver. With such RDBSS, it's possible for the driver to mount a remote share, to list
files, to query their properties, to query volume properties, and finally to read files (with some corruption under
specific conditions).
Please refrain from committing in this (especially for modifying whitespaces or fixing comments...), this is still WIP
and under development, it would mess with my local changes!
In itself, it doesn't bring anything to ReactOS yet, as no mini redirector is available in ReactOS source tree.
This may come later on with NFS41.

[RDBSS]
- Implement RxCloseAssociatedSrvOpen(), RxFastIoRead(), RxPurgeNetFcb(), RxRemoveShareAccess(), RxRemoveShareAccessPerSrvOpens()
- Continue implementation of RxCommonCleanup() to handle allocated SRV_OPEN
- Halfplement RxFastIoCheckIfPossible() so that it handles read operations
- Stub RxCancelNotifyChangeDirectoryRequestsForFobx()
[RXCE]
- Implement RxChangeBufferingState(), RxFinalizeSrvOpen(), RxFreeFcbObject(), RxGatherRequestsForSrvOpen(), RxGetDeviceObjectOfInstance(), RxInitializeRxTimer(), RxMarkFobxOnCleanup(), RxMarkFobxOnClose(), RxpDiscardChangeBufferingStateRequests(), RxpDispatchChangeBufferingStateRequests(), RxpLookupSrvOpenForRequestLite(), RxpMarkInstanceForScavengedFinalization(), RxPostOneShotTimerRequest(), RxPrepareRequestForReuse(), RxProcessChangeBufferingStateRequestsForSrvOpen(), RxpUndoScavengerFinalizationMarking(), RxPurgeChangeBufferingStateRequestsForSrvOpen(), RxPurgeFobxFromCache(), RxRemoveNameNetFcb(), RxScavengerTimerRoutine(), RxTimerDispatch()
- Finish implementation of RxDereference() to handle scavenger
- Finish implementation of RxLowIoCompletionTail() to handle blocked operations resume
- Fix a bug in RxFinalizeNetFcb() where it was dereferencing its NET_ROOT instead of its V_NET_ROOT
- Fix bugs in __RxAcquireFcb() where it improperly handled the lack of RX_CONTEXT
- Halfplement RxResumeBlockedOperations_ALL() to extract blocked operations from RX_CONTEXT (and drop them...)
- Stub RxDispatchChangeBufferingStateRequests(), RxScavengerFinalizeEntries()
[COPYSUP]
- Implement FsRtlCopyRead2()
This library is basically what you can find in FsRtl with an extended support of Top Level IRP. It is used by RDBSS for FastIO. Next to come in it will be FsRtlCopyWrite2().
This commit brings several improvements to current work on RBDSS/RXCE. First of all, both libraries will leak less (again!).
It also brings the scavenger infrastructure (not fully fonctionnal though). Our NFS driver doesn't make use of it though.
Finally, this brings support of FastIO (for read operations ;-)) to our NFS driver!
Regarding CORE-13484, with copy + FastIO I could copy a file without troubles. But that seems to be still problematic with xcopy without FastIO...
