Description of Patch
New Files

This class extends from LOBStreamControl and provides wrapper methods to uses
Strings to access LOBData.
java/engine/org/apache/derby/impl/jdbc/ClobAsciiStream.java
A Stream which assumes all the bytes coming in is ascii char and passes it on
to Writer.
java/engine/org/apache/derby/impl/jdbc/ClobUtf8Writer.java
This class uses ClobStreamControl to updates the clob. User will get this
object when it makes calls to retrieve outputstream from clob.
java/engine/org/apache/derby/impl/jdbc/EmbedClob.java
Modified to use ClobStreamControl when the clob is materialized.
Added additional set methods.
java/engine/org/apache/derby/impl/jdbc/UTF8Reader.java
Added a new constructor to accept length as parameter. When the length is
passed to the constructor, it doesn't tries to read the length from the stream
and considers the data from the beginning of the stream.
java/engine/org/apache/derby/impl/jdbc/LOBStreamControl.java
Added a new method to replace bytes in the middle of file/array when the new
bytes may have a diff length from the original bytes.
