Subject: [PATCH 1/3] term: improve the demuxer
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.
* term/main.c (demuxer): Improve the demuxer function.
