nginx-0.3.38-RELEASE import

    *) Feature: the ngx_http_dav_module.

    *) Change: the ngx_http_perl_module optimizations.
       Thanks to Sergey Skvortsov.

    *) Feature: the ngx_http_perl_module supports the $r->request_body_file
       method.

    *) Feature: the "client_body_in_file_only" directive.

    *) Workaround: now on disk overflow nginx tries to write access logs
       once a second only.
       Thanks to Anton Yuzhaninov and Maxim Dounin.

    *) Bugfix: now the "limit_rate" directive more precisely limits rate if
       rate is more than 100 Kbyte/s.
       Thanks to ForJest.

    *) Bugfix: now the IMAP/POP3 proxy escapes the "\r" and "\n" symbols in
       login and password to pass authorization server.
       Thanks to Maxim Dounin.
