Revision 1576716

Merge r1575400 from trunk:

CVE-2014-0098 (reported by Rainer Canavan <rainer-apache 7val com>)
Segfaults w/ truncated cookie logging.

Clean up the cookie logging parser to recognize only the cookie=value pairs,
not valueless cookies.  This refactors multiple passes over the same string
buffer into a single pass parser.
