nginx-0.3.17-RELEASE import

    *) Change: now on Linux configure checks the presence of epoll and
       sendfile64() in kernel.

    *) Feature: the "map" directive supports domain names in the
       ".domain.tld" form.

    *) Bugfix: the timeouts were not used in SSL handshake; the bug had
       appeared in 0.2.4.

    *) Bugfix: in the HTTPS protocol in the "proxy_pass" directive.

    *) Bugfix: when the HTTPS protocol was used in the "proxy_pass"
       directive the port 80 was used by default.
