Updated OCI8Connection parameter name in order to separate oracle pooling handling with oci8 persistent connections

Adding PDO::FETCH_COLUMN support to OCI8 fetchAll method using the fetch structure OCI_FETCHSTATEMENT_BY_COLUMN.

This enables a more natural way of interacting with result sets,
and re-introduces in Doctrine DBAL a feature that has been available
in PDO from the begining.

Fix bug where empty or null host connection parameter will still construct an Oracle DSN instead of using dbname.

Patch for OCI8Statement to support param[0] being null. Switched isset to array_key_exists. Added test that demonstrates the bug and confirms the fix.

to be able to make OCI8 derived classes
