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.

Previously, TPipedTransport wrote it's full buffer to the "pipe" and
fully reset its buffer on a readEnd. This assumed that the buffer was
fully read at that point. This is not the case if requests are pipelined.
This change makes it only pipe out the portion that has been read and
copy the unread portion to the beginning of the buffer.
Also add a test that verifies the new functionality.
