add 'no-input-specified' error code if all inputs to LSParser are null

           Summary: add 'no-input-specified' error code if all inputs to
                    LSParser are null
           Product: Xerces2-J
           Version: 2.6.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: DOM
        AssignedTo: xerces-j-dev@xxxxxxxxxxxxxx
        ReportedBy: nnissar@xxxxxxxxxx


PR addition to DOM LS spec, stating that "If all inputs are null, the LSParser 
will report a DOMError with its DOMError.type set to "no-input-specified" and 
its DOMError.severity set to DOMError.SEVERITY_FATAL_ERROR." [1] 

Also spec states "The LSParser will use the LSInput object to determine how to 
read data...looking at the different inputs specified in the LSInput in the 
following order to know which one to read from, the first one that is not null 
and not an empty string will be used: 

1.LSInput.characterStream 
2.LSInput.byteStream 
3.LSInput.stringData 
4.LSInput.systemId 
5.LSInput.publicId 

Currently, we are not looking at the inputs in the specified order.  I've 
included that minor rearrangement in dom2xmlInputSource in the proposed patch 
as well.
