RFE - add generic accessors to SQLInput, SQLOutput

because bugparade is not working, I post this here :-(

There could be:

public <T> T read() throws SQLException;
public <T> void write(T obj) throws SQLException;

Alternatively, maybe readObject(), writeObject() could be re-engineered with generic API.

All other methods then could be deprecated !

E.g. in javax.sql.rowset.serial.SQLInputImpl the code simply could be:
(private getNextAttribute() could be dropped)

     // rename Object[] attrib to attribs !!!

     public <T> T readObject() throws SQLException {
         if (++idx >= attribs.length) {
             throw new SQLException("SQLInputImpl exception: Invalid read " +
         Object attrib = attribs[idx];
         lastValueWasNull = attrib == null;
         if (attrib instanceof Struct) {
         return (T)attrib;
