Log Message:
Implement retransmit logic for the SYN cache engine.  Fixes a rare condition
where one side can think a connection exists, where the other side thinks
the connection was never established.

The original problem was first reported by Ty Sarna in PR #5909.  The
original fix I made to the code didn't cover all cases.  The problem this
fix addresses was reported by Christoph Badura via private e-mail.

Many thanks to Bill Sommerfeld for helping me to test this code, and
for finding a subtle bug.
