Subject: [PATCH] Disable TCP_DEBUG and FASTRETRANS_DEBUG by default

From: Dan McGee <[email-masked]>
Date: Mon, 17 Oct 2011 15:25:24 -0500

If these are truly debug options, they should be turned off by default
and can be tweaked if necessary. Fix one usage of the flag to use #if
instead of #ifdef so defining to zero is acceptable.
