restore the generic proxy workers to not being address-reusable.  

The guts of mod_proxy is not really ready for the addr and host on a 
proxy_conn_rec to change over time and differ from the 1 cached in the worker.

* proxy_worker->cp->addr needs to know what host/port it cached
* conn->addr and conn->hostname need to be allocated from their own subpool
  so they can be cleared as they change
* ap_proxy_determine_connection needs to be more careful about which
  addr is the TCP endpoint and what we have in either cache.
* may need to avoid updating the proxy_worker addr cache if we know
  the value is flipping.



Update the comment and checks around address/connection reusability
in mod_proxy.  

The checks and comment are a vestige of 2.0.x
mod_proxy_http where the backend proxy conn was stored in 
the frontend r->conn_config, but ap_proxy_determine_connection()
doesn't associate the frontend and backend conns like this.

Set OPENSSL_NO_SSL_INTERN when compiling against OpenSSL 1.0.1
or later, so that mod_ssl retains binary compatibility with future
versions when internal structures are changed. Use API functions
where available, and fall back to direct access for OpenSSL up

never used by any released version of mod_ssl.

REMOTE_ADDR is now r->useragent_ip, which is not/never available at
