Changes with nginx 0.8.36 22 Apr 2010

    *) Bugfix: the ngx_http_dav_module handled incorrectly the DELETE,
       COPY, and MOVE methods for symlinks.

    *) Bugfix: values of the $query_string, $arg_..., etc. variables cached
       in main request were used by the SSI module in subrequests.

    *) Bugfix: a variable value was repeatedly encoded after each an "echo"
       SSI-command output; the bug had appeared in 0.6.14.

    *) Bugfix: a worker process hung if a FIFO file was requested.
       Thanks to Vicente Aguilar and Maxim Dounin.

    *) Bugfix: OpenSSL-1.0.0 compatibility on 64-bit Linux.
       Thanks to Maxim Dounin.

    *) Bugfix: nginx could not be built --without-http-cache; the bug had
       appeared in 0.8.35.
