nginx-0.3.58-RELEASE import

    *) Feature: the "error_page" directive supports the variables.

    *) Change: now the procfs interface instead of sysctl is used on Linux.

    *) Change: now the "Content-Type" header line is inherited from first
       response when the "X-Accel-Redirect" was used.

    *) Bugfix: the "error_page" directive did not redirect the 413 error.

    *) Bugfix: the trailing "?" did not remove old arguments if no new
       arguments were added to a rewritten URI.

    *) Bugfix: nginx could not run on 64-bit FreeBSD 7.0-CURRENT.
