Added support for JDBC3. The driver will now build under JDBC3 (i.e. Java 1.4). 

This concludes my changes that restructured the code to support JDBC3.
The jdbc unit tests were also resturctured to allow different tests between
jdbc2 and jdbc3, although currently make check (aka ant test) for JDBC3 just
runs the JDBC2 tests.  Of special note the largeobject/PGblob and PGclob
classes have been moved under the jdbc2/jdbc3 specific directories as they
now differ by jdbc version.  Also note that this checkin removes the
PostgresqlDataSource and files in the xa directory.  A recent checkin has
added new datasource support that replaces the functionality provided by these
classes.

/*
* Implements a JDBC 2.0 {@link javax.sql.DataSource} for the
* PostgreSQL driver with JNDI persistance support. XA and pooled
* connection support is also available, but the application must
* used the designated DataSource interface to obtain them.
* <p>
* The supported data source properties are:
* <pre>
* description (optional)
* databaseName (required)
* loginTimeout (optional)
* user (optional)
* password (optional)
* serverName (optional)
* portNumber (optional)
* transactionTimeout (optional for XA connections)
* </pre>
* This data source may be serialized and stored in a JNDI
* directory. Example of how to create a new data source and
* register it with JNDI:
* <pre>
* PostgresqlDataSource ds;
* InitialContext ctx;
*
* ds = new PostgresqlDataSource();
* ds.setDatabaseName( "test" );
* ds.setUser( "me" );
* ds.setPassword( "secret" );
* ctx = new InitialContext();
* ctx.rebind( "/comp/jdbc/test", ds );
* </pre>
* Example for obtaining the data source from JNDI and
* opening a new connections:
* <pre>
* InitialContext ctx;
* DataSource ds;
*
* ctx = new InitialContext();
* ds = (DataSource) ctx.lookup( "/comp/jdbc/test" );
* ds.getConnection();
