Define BOOST_NETWORK_MESSAGE if BOOST_NETWORK_DEBUG

The internal macro BOOST_NETWORK_MESSAGE is meant
to insert debugging output that by default prints
to std::cerr. This macro is only enabled if
BOOST_NETWORK_DEBUG is defined. This is not meant
to be exposed and is only meant to be for debugging
purposes during development.
