bug #955 - Fix SSL parsing issue.

The parser wasn't carrying out a bounds check on record length while
in the middle of parsing a handshake.  As a result we would step onto the
next record header and consider it a part of the current handshake.

- Contains an unittest to test the issue.
- Disable the duplicate parser unittest registration.

The issue came to light through an irregular ssl record, which was
reported by Sebastian Roschke, via CVE-2013-5919.

Thanks to Sebastian Roschke for reporting this issue.
