Subject: Added SSL support from Christian Starkjohann <cs@obdev.at> This patch
 may not yet compile with -DUSE_SSL enabled, further Makefile changes may be
 needed. But it was important to get this code in place before I go off to
 USENIX. Jeremy. (This used to be commit
 31e768369fdc61e07c59630c86c62239f3d3f3f7)
