I maxim

I spent some time to rewrite my previous patch to make it better (at
least I think and I hope).

I added two directives for each upstream (proxy, fastcgi and uwsgi)
which is called

fastcgi_hide_cache_header (the alter ego of fastcgi_hide_header).
fastcgi_pass_cache_header (the alter ego of fastcgi_pass_header).

proxy_hide_cache_header (the alter ego of proxy_hide_header).
proxy_pass_cache_header (the alter ego of proxy_pass_header).

uwsgi_hide_cache_header (the alter ego of uwsgi_hide_header).
uwsgi_pass_cache_header (the alter ego of uwsgi_pass_header).


(fastcgi_hide_headers - fastcgi_pass_headers) hides headers no matter
if the request is cacheable.
(fastcgi_hide_cache_header - fastcgi_pass_cache_header) hides headers
only if the request is cacheable.


The default headers for fastcgi_hide_headers are:
ngx_string("Status"),
ngx_string("X-Accel-Expires"),
ngx_string("X-Accel-Redirect"),
ngx_string("X-Accel-Limit-Rate"),
ngx_string("X-Accel-Buffering"),
ngx_string("X-Accel-Charset"),

The default headers for facstcgi_hide_cache_headers are:
ngx_string("Set-Cookie"),
ngx_string("P3P"),

I hope this patch is better than the previous one. I tried to stay in
the nginx philosophy. I hope I succedeed.
