HTTP/2: discard remaining request body after redirect.
Previously, if unbuffered request body reading wasn't finished before
the request was redirected to a different location using error_page
or X-Accel-Redirect, and the request body is read again, this could
lead to disastrous effects, such as a duplicate post_handler call or
"http request count is zero" alert followed by a segmentation fault.
This happened in the following configuration (ticket #1819):
location / {
proxy_request_buffering off;
proxy_pass http://bad;
proxy_intercept_errors on;
error_page 502 = /error;
}
location /error {
proxy_pass http://backend;
}
