nginx-0.1.12-RELEASE import

    *) Feature: the %request_length log parameter.

    *) Bugfix: when using the /dev/poll, select and poll on the platforms,
       where these methods may do the false reports, there may be the long
       delay when the request was passed via the keep-alive connection. It
       may be at least on Solaris when using the /dev/poll.

    *) Bugfix: the send_lowat directive is ignored on Linux because Linux
       does not support the SO_SNDLOWAT option.
