Update to 0.11.6 (as 0.999.11.6). No changelog, but changes are supposed
to match those of ucspi-tcp6 1.11.6, so:

- Fixed problem for sslserver binding to local IPv4 addresses. Improved
  selection of IP addresses given the user flags -4/-6 and none.
- Improved sslclient's binding given several hostnames available in DNS.
