[Libguestfs] [PATCH] daemon: proto: Remove pervasive but useless debugging messages.

If you spend your time looking at libguestfs debugging output you'll see many messages from the daemon main loop like this: guestfsd: main_loop: new request, len 0x54 guestfsd: main_loop: proc 278 (mkfs) took 0.02 seconds I don't think these messages really bring much value. This commit removes them entirely. An alternative might be to change them to make them shorter and/or less useless, but I'm not sure what that would be. Rich.
