Subject: trans: improve demuxers

Handle multiple request types as recommended by the Mach Server
Writer's Guide section 4, subsection "Handling Multiple Request
Types".  This avoids initializing the reply message in every X_server
function.

* trans/proxy-defpager.c (proxy_defpager_demuxer): Improve the demuxer
function.
* trans/streamio.c (demuxer): Likewise.
