Initial restructuring to add jdbc3 support. There was a significant amount 

of duplicated code between the jdbc1 and jdbc2.  This checkin restructures
the code so that the duplication is removed so that the jdbc3 support
can be added without adding yet another copy of everything.  Also many
classes were renamed to avoid confusion with multiple different objects
having the same name.  The timestamp tests were also updated to add support
for testing timestamp without time zone in addition to timestamp with time zone

/*
* A ResultSet provides access to a table of data generated by executing a
* Statement. The table rows are retrieved in sequence. Within a row its
* column values can be accessed in any order.
*
* <P>A ResultSet maintains a cursor pointing to its current row of data.
* Initially the cursor is positioned before the first row. The 'next'
* method moves the cursor to the next row.
*
* <P>The getXXX methods retrieve column values for the current row. You can
* retrieve values either using the index number of the column, or by using
* the name of the column. In general using the column index will be more
* efficient. Columns are numbered from 1.
*
* <P>For maximum portability, ResultSet columns within each row should be read
* in left-to-right order and each column should be read only once.
*
*<P> For the getXXX methods, the JDBC driver attempts to convert the
* underlying data to the specified Java type and returns a suitable Java
* value. See the JDBC specification for allowable mappings from SQL types
* to Java types with the ResultSet getXXX methods.
*
* <P>Column names used as input to getXXX methods are case insenstive. When
* performing a getXXX using a column name, if several columns have the same
* name, then the value of the first matching column will be returned. The
* column name option is designed to be used when column names are used in the
* SQL Query. For columns that are NOT explicitly named in the query, it is
* best to use column numbers. If column names were used there is no way for
* the programmer to guarentee that they actually refer to the intended
* columns.
*
* <P>A ResultSet is automatically closed by the Statement that generated it
* when that Statement is closed, re-executed, or is used to retrieve the
* next result from a sequence of multiple results.
*
* <P>The number, types and properties of a ResultSet's columns are provided by
* the ResultSetMetaData object returned by the getMetaData method.

* A ResultSet provides access to a table of data generated by executing a
* Statement. The table rows are retrieved in sequence. Within a row its
* column values can be accessed in any order.
*
* <P>A ResultSet maintains a cursor pointing to its current row of data.
* Initially the cursor is positioned before the first row. The 'next'
* method moves the cursor to the next row.
*
* <P>The getXXX methods retrieve column values for the current row. You can
* retrieve values either using the index number of the column, or by using
* the name of the column. In general using the column index will be more
* efficient. Columns are numbered from 1.
*
* <P>For maximum portability, ResultSet columns within each row should be read
* in left-to-right order and each column should be read only once.
*
*<P> For the getXXX methods, the JDBC driver attempts to convert the
* underlying data to the specified Java type and returns a suitable Java
* value. See the JDBC specification for allowable mappings from SQL types
* to Java types with the ResultSet getXXX methods.
*
* <P>Column names used as input to getXXX methods are case insenstive. When
* performing a getXXX using a column name, if several columns have the same
* name, then the value of the first matching column will be returned. The
* column name option is designed to be used when column names are used in the
* SQL Query. For columns that are NOT explicitly named in the query, it is
* best to use column numbers. If column names were used there is no way for
* the programmer to guarentee that they actually refer to the intended
* columns.

* when that Statement is closed, re-executed, or is used to retrieve the
* next result from a sequence of multiple results.
