[hbirr] 14296: - Guarded the calls to IoSetCancelRoutine with IoAcquireCancelSpinLock/IoReleaseCancelSpinLock.

- Guarded the calls to IoSetCancelRoutine with IoAcquireCancelSpinLock/IoReleaseCancelSpinLock. - Used a fastmutex as lock for the data queue. - Used paged pool for the data buffers. - Allowed the server to read (and to wait) on a listening pipe. - Implemented the non blocking read operations.
