Partial revamp of the JdbcClient.  It needs some work. - Changed argument parsing system - Changed and added argument options - updated help message - implemented batching mode   + batching mode allows to execute COPY x RECORDS INTO syntax   + batching mode should remove a lot of Java processing   + batching mode however seems to be slower than single statement mode;     * consuming the large amounts of update counts from the server is a       hell for the JDBC driver     * due to the concentration of data CPU time is used more       inefficiently, threads cannot do work while others are blocked,       since they all wait for the same     * specifying smaller chunks increases speed :(     * conclusion: batching this way sucks, need proper server support     * remarkable point: using larger chunks, the client seems to hang       at a certain point while it tries to send more data to the server.
Partial revamp of the JdbcClient.  It needs some work.
- Changed argument parsing system
- Changed and added argument options
- updated help message
- implemented batching mode
  + batching mode allows to execute COPY x RECORDS INTO syntax
  + batching mode should remove a lot of Java processing
  + batching mode however seems to be slower than single statement mode;
    * consuming the large amounts of update counts from the server is a
      hell for the JDBC driver
    * due to the concentration of data CPU time is used more
      inefficiently, threads cannot do work while others are blocked,
      since they all wait for the same
    * specifying smaller chunks increases speed :(
    * conclusion: batching this way sucks, need proper server support
    * remarkable point: using larger chunks, the client seems to hang
      at a certain point while it tries to send more data to the server.
