  Modified:    java/src/org/apache/soap/transport TransportMessage.java
               java/src/org/apache/soap Constants.java
  Log:
  Fix a bug introduced in previous changes when their is an envelope editor
  and no envelope was explitictly specified (just a rootPart in SOAPContext).
  Prevent duplicate assignment of rootPart when original envelope is empty.
  Side-step MIME serialization when the message is only a SOAP envelope.
  Improve MIME serialization by starting with a larger byte output stream.
  Move some constants.
