The old implementations of the memory-based transports (TBufferedTransport,
TFramedTransport, and TMemoryBuffer) shared very little code and all worked
a bit differently. This change unifies them all as subclasses of a single
base (TBufferBase) which handles the fast-path operations (when requests
can be satisfied by the buffer) with inline methods (that will eventually
be made nonvirtual in the template branch) and calls out to pure-virutal
methods to handle full/empty buffers. All of the buffer-management is now
done in terms of "base and bound" pointers rather than "pos" integers.
These classes were moved to TBufferTransports.{h,cpp}. The .h is included
in TTransportUtils for backwards compatibility.
Also added a "TShortReadTransport" to assist testing transports.
