Yann Ylavic c15471ee3b mod_proxy: restore reuse of ProxyRemote connections when possible.

Fixes a regression from 2.4.59 (r1913907).

For a reverse proxy setup with a worker (enablereuse=on) and a
forward/CONNECT ProxyRemote to reach it, an open connection/tunnel
to/through the remote proxy for the same origin server (and using the
same proxy auth) should be reusable. Avoid closing them like r1913534
did.

* modules/proxy/proxy_util.c:
  Rename the struct to remote_connect_info since it's only used for
  connecting through remote CONNECT proxies. Axe the use_http_connect
  field, always true.

* modules/proxy/proxy_util.c(ap_proxy_connection_reusable):
  Remote CONNECT (forward) proxy connections can be reused if the auth
  and origin server infos are the same, so conn->forward != NULL is not
  a condition to prevent reusability.

* modules/proxy/proxy_util.c(ap_proxy_determine_connection):
  Fix the checks around conn->forward reuse and connection cleanup if
  that's not possible.
