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.
