commit 1361b3742df0c5c8d51272248ff70164d0a3cd11
from: Alexander Barton <alex@barton.de>
date: Tue Aug 23 10:28:04 2011 UTC

Introduce DEBUG_BUFFER, rework some debug messages

DEBUG_BUFFER is off by default and therefore disables these messages:
 - "Handle_Write() called for connection XX, YY bytes pending ..."
 - "Connection XX: ZZ bytes left in read buffer."
