Bug description: Coll->assignElem(n,"str") and Coll->append("str") causes
memory leak
Description:
------------
I found that
coll->append("string");
or
coll->assignElem(n,"string");
cause memory leak.
You need to free OCIAssignText()'ed strings with OCIStringResize() in
oci8.c (PHP 4.4.6) and oci8_collection.c (PHP 5.2.1, PECL/oci8-1.2.3)
because OCICollAppend() and OCICollAssignElem() perform deep-copy of
element value.

Reproduce code:
---------------
$collStr = ocinewcollection( ... );
$collStr->append("string"); /* memory leak */
$collStr->assignElem(0,"string"); /* memory leak */
$collNum = ocinewcollection( ... );
$collNum->append(1234); /* no memory leak */
$collNum->assignElem(0, 5678); /* no memory leak */
$collDate = ocinewcollection( ... );
$collDate->append("2007-01-01"); /* no memory leak */
$collDate->assignElem(0, "2007-02-02"); /* no memory leak */
Expected result:
----------------
no memory leak
Actual result:
--------------
memory leak
