* - Protocol is determined either by the request or a combination of
* system.ssl_policy and the $ssl parameter.
* - Host name is determined either by system.hostname or inferred from request
* - Path is inferred from SCRIPT_NAME
*
* @param bool $ssl
* @return string
* Caches the result (depending on $ssl value) for performance.
*
* Note: $ssl parameter value doesn't directly correlate with the resulting protocol
*
* @param bool $ssl Whether to append http or https under SSL_POLICY_SELFSIGN
* @return string Friendica server base URL
