Tests: tests for usage of discarded body.
The client_max_body_size limit should be ignored when the request body
is already discarded. In HTTP/1.x, this is done by checking the
r->discard_body flag when the body is being discarded, and because
r->headers_in.content_length_n is 0 when it's already discarded. This,
however, does not happen with HTTP/2 and HTTP/3, and therefore
"error_page 413" does not work without relaxing the limit.
Further, with proxy_pass, r->headers_in.content_length_n is used to determine
length of the request body, and therefore is not correct if discarding of
the request body isn't yet complete. While discarding the request body,
r->headers_in.content_length_n contains the rest of the body to discard
(or, in case of chunked request body, the rest of the current chunk to
discard).
Similarly, the $content_length variable uses r->headers_in.content_length
if available, and also incorrect. The $content_length variable is used
when proxying with fastcgi_pass, grpc_pass, and uwsgi_pass (scgi_pass uses
the value calculated based on the actual request body buffers, and therefore
works correctly).
