Changes with nginx 0.8.1 08 Jun 2009

*) Feature: the "updating" parameter in "proxy_cache_use_stale" and
"fastcgi_cache_use_stale" directives.

*) Bugfix: the "If-Modified-Since", "If-Range", etc. client request
header lines were passed to backend while caching if no
"proxy_set_header" directive was used with any parameters.

*) Bugfix: the "Set-Cookie" and "P3P" response header lines were not
hidden while caching if no "proxy_hide_header/fastcgi_hide_header"
directives were used with any parameters.

*) Bugfix: the ngx_http_image_filter_module did not support GIF87a
format.
Thanks to Denis Ilyinyh.

*) Bugfix: nginx could not be built modules on Solaris 10 and early;
the bug had appeared in 0.7.56.
