Description:
------------
The variable maxlength has no effect in the memory usage for a bind variable OUT.

A bind variable OUT takes systematically 65536 bytes in memory.

Test script:
---------------
$sql = "CALL TEST.PROC_OUT(:OUT)";
$curseur = oci_parse($connexion, $sql);
$out="1";
$size=10;
oci_bind_by_name($curseur,":OUT", $out, $size);

var_dump(memory_get_usage());
$ok = oci_execute($curseur);
oci_free_statement($curseur);
var_dump(memory_get_usage());


Expected result:
----------------
Memory should be consistency with the maxlength parameter.

Actual result:
--------------
Playing with memory settings, we obtain :

PHP Fatal error:  Allowed memory size of 10752000 bytes exhausted (tried to allocate 65536 bytes)
