Fixes to enable REQ/REP to operate.

This uncovered a few problems - inproc was not moving the headers
to the body on transmit, and the message chunk allocator had a serious
bug leading to memory corruption.  I've also added a message dumper,
which turns out to be incredibly useful during debugging.
