Upstream: don't consider default_port when matching upstreams.
The only thing that default_port comparison did in the current
code is prevented implicit upstreams to the same address/port
from being aliased for http and https, e.g.:
proxy_pass http://10.0.0.1:12345;
proxy_pass https://10.0.0.1:12345;
This is inconsistent because it doesn't work for a similar case
with uswgi_pass:
uwsgi_pass uwsgi://10.0.0.1:12345;
uwsgi_pass suwsgi://10.0.0.1:12345;
or with an explicit upstream:
upstream u {
server 10.0.0.1:12345;
}
proxy_pass http://u;
proxy_pass https://u;
Before c9059bd5445b, default_port comparison was needed to
differentiate implicit upstreams in
proxy_pass http://example.com;
and
proxy_pass https://example.com;
as u->port was not set.
