Log:
DERBY-1440: jdk 1.6 client driver omits SQLStates and chained exceptions in
error messages

While working on DERBY-2472 I found out what caused this difference between
the JDBC 3.0 driver and the JDBC 4.0 driver. There are three
problems. Firstly, StandardException.unexpectedUserException() doesn't
recognize that an SQLException is generated Derby since it is not an
EmbedSQLException. Secondly, TransactionResourceImpl.wrapInSQLException()
invokes SQLException.setNextException() explicitly so that the required
chaining/ferrying logic in the exception factory and in EmbedSQLException's
constructor is not used. Thirdly,
SQLException40.wrapArgsForTransportAcrossDRDA() puts a standard
SQLException, not an EmbedSQLException, in the argument ferry's
next-exception chain, which prevents the network server from seeing it as a
Derby exception.

The attached patch fixes the problem by

  1) using SQLExceptionFactory.getArgumentFerry() to find out whether the
     exception is a Derby exception in unexpectedUserException()

  2) using factory methods instead of setNextException() to do the chaining
     in wrapInSQLException()

  3) improving Util.javaException() so that it sets up a next-exception
     chain if the Java exception contains nested exceptions

  4) changing wrapArgsForTransportAcrossDRDA() to create an argument ferry
     whose next exception is the argument ferry of the main exception's next
     exception

This patch also fixes all the JUnit tests that contain code looking like this:

    assertStatementError(JDBC.vmSupportsJDBC4() ? "38000" : "42X62", cSt);

Now, the check for JDBC level is not needed anymore for those tests.
