mod_proxy: Add ap_connection_reusable() for checking if a connection

Browse Source 
is reusable as of this point in processing.

mod_proxy_fcgi uses the new API to determine if FCGI_CONN_CLOSE
should be enabled, but that doesn't change existing behavior
since the connection is currently marked for closure elsewhere
in the module.
