'RELENG_2_2_1_RELEASE'.

This commit was manufactured to restore the state of the 2.2.1-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Turn on SO_KEEPALIVE on network connections. Since we limit the number

of connections, we cannot afford to allow "disappeared" client to cause
us to leave one of the 14 connections open and hanging in a read() forever.

(SO_KEEPALIVE causes probe packets to be sent after a few hours of IDLE
time where no data has been transferred.  Sup should NEVER do this, so the
only time it will have an effect is if it looses the remote machine)

The heritage of this version is not clear.  It appears to be NetBSD
derived from some time ago.
