nginx-0.3.31-RELEASE import

    *) Change: now nginx passes the malformed proxied backend responses.

    *) Feature: the "listen" directives support the address in the "*:port"
       form.

    *) Feature: the EVFILER_TIMER support in MacOSX 10.4.

    *) Workaround: for MacOSX 64-bit kernel kqueue millisecond timeout
       bug.
       Thanks to Andrei Nigmatulin.

    *) Bugfix: if there were several "listen" directives listening one
       various addresses inside one server, then server names like
       "*.domain.tld" worked for first address only; the bug had appeared
       in 0.3.18.

    *) Bugfix: if the HTTPS protocol was used in the "proxy_pass" directive
       and the request body was in temporarily file then the request was
       not transferred.

    *) Bugfix: perl 5.8.8 compatibility.
