Cluster prototype: handles client-initiated commands (not dequeues)

Details
 - Cluster.cpp: serializes all frames thru cluster (see below)
 - broker/ConnectionManager: Added handler chain in front of Connection::received.
 - sys::Fork and ForkWithMessage - abstractions for forking with posix impl.
 - tests/ForkedBroker.h: test utility to fork a broker process. 
 - broker/SignalHandler: Encapsulated signal handling from qpidd.cpp
 - Various minor logging & error message improvements to aid debugging.

NB: current impl will not scale. It is functional working starting point so we
can start testing & profiling to find the right optimizations.
