Subject: [PATCH] buffer: Fail early and print diagnostic message

When /tmp/mist/ was created before as a different user, and MistBuffer was
started, it would print "End of input file - buffer shutting down". This is very
confusing, therefore fail earlier and print a more useful message even if DEBUG
is disabled.
