nginx-0.3.27-RELEASE import

    *) Change: the "variables_hash_max_size" and
       "variables_hash_bucket_size" directives.

    *) Feature: the $body_bytes_sent variable can be used not only in the
       "log_format" directive.

    *) Feature: the $ssl_protocol and $ssl_cipher variables.

    *) Feature: the cache line size detection for widespread CPUs at start
       time.

    *) Feature: now the "accept_mutex" directive is supported using
       fcntl(2) on platforms different from i386, amd64, sparc64, and ppc.

    *) Feature: the "lock_file" directive and the --with-lock-path=PATH
       autoconfiguration directive.

    *) Bugfix: if the HTTPS protocol was used in the "proxy_pass" directive
       then the requests with the body was not transferred.
