* ext/openssl/ossl_ssl.c (ossl_ssl_shutdown): Try to shutdown SSL
connection more gracefully. Call SSL_shutdown() max 4 times until it
returns 1 (success). Bi-directional SSL close has several states but
SSL_shutdown() kicks only 1 transition per call. Max 4 is from
mod_ssl.c of Apache httpd that says 'max 2x pending * 2x data = 4'.
See #4237.
