Previously nginx used to mark backend again as live as soon as fail_timeout
passes (10s by default) since last failure.  On the other hand, detecting
dead backend takes up to 60s (proxy_connect_timeout) in typical situation
"backend is down and doesn't respond to any packets".  This resulted in
suboptimal behaviour in the above situation (up to 23% of requests were
directed to dead backend with default settings).

More detailed description of the problem may be found here (in Russian):
http://mailman.nginx.org/pipermail/nginx-ru/2011-August/042172.html

Fix is to only allow one request after fail_timeout passes, and
mark backend as "live" only if this request succeeds.

Note that with new code backend will not be marked "live" unless "check"
request is completed, and this may take a while in some specific workloads
(e.g. streaming).  This is believed to be acceptable.

Clear old Location header (if any) while adding a new one.

This prevents incorrect behaviour when another redirect is issued within
error_page 302 handler.

Wording fix, "many data" is incorrect.
