*) 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.
