*Reorganized files with astyle utility.
*NpgsqlState.cs, NpgsqlClosedState.cs, NpgsqlReadState.cs, NpgsqlStartupState.cs:
Changed code to use a buffered stream on demand instead of using the cached BufferedStream. It as giving hangs.
*NpgsqlEventLog.cs:
Removed the obsolete warning from file and changed the signature of the method from public to private. This make the building cleaner.
*NpgsqlCommand.cs, NpgsqlDataReader.cs:
Added support for CloseCommand behavior.
*NpgsqlConnection.cs:
Removed the cached BufferedStream. Now only uses the raw Stream.
*NpgsqlParameter:
Fixed a small bug which prevented the parameter name and its value from being set if the value of parameter was null.
