nginx-0.3.18-RELEASE import

*) Feature: the "server_names" directive supports the ".domain.tld"
       names.

    *) Feature: the "server_names" directive uses the hash for the
       "*.domain.tld" names and more effective hash for usual names.

    *) Change: the "server_names_hash_max_size" and
       "server_names_hash_bucket_size" directives.

    *) Change: the "server_names_hash" and "server_names_hash_threshold"
       directives were canceled.

    *) Feature: the "valid_referers" directive uses the hash site names.

    *) Change: now the "valid_referers" directive checks the site names
       only without the URI part.

    *) Bugfix: some ".domain.tld" names incorrectly processed by the
       ngx_http_map_module.

    *) Bugfix: segmentation fault was occurred if configuration file did
       not exist; the bug had appeared in 0.3.12.

    *) Bugfix: on 64-bit platforms segmentation fault may occurred on
       start; the bug had appeared in 0.3.16.
