Review request for qpid, Gordon Sim and Rafael Schloming.


Bugs: PROTON-837
    https://issues.apache.org/jira/browse/PROTON-837


Repository: qpid-proton-git


Description
-------

simple_send.c provides a simple send/receive example over a single
outgoing connection.

simple_echo.c provides a simple server that manages multiple incoming
connections from simple_send (or msgr-send, or reactor-send).

uv_iohandler.c provides an external loop substitute to drive Proton
events.  It can be combined with simple_echo as written and with
arbitrary other programs with minor tweaks.


simple_send and simple_echo will benefit from review as to suitability
for good tutorial material for using the Proton reactor event model,
especially for correctness and clarity.

uv_iohandler is more a proof of concept and hopefully demonstrates a
decent blueprint for integrating other external loops into Proton.
