Fixed bug #44372 (compilation with Oracle 10gR1 libraries)
http://bugs.php.net/bug.php?id=44372

Updated updated error number list to improve re-connection
behavior after a database restart.

Guard against potential internal list corruption after ping
removes old oci_pconnect() information.

Fix ini_set("oci8.connection_class", "abc") to get an appropriate
persistent connection.

Ping at oci8.ping_interval for oci_connect() and oci_new_connect()
when DRCP connections are used. This improves non-persistent
connection reliability if a database gets restarted.
