Initial investigation into dtcp issue where encrypted content does not play.  Make sure parameters are initialized to zero and null.  Added additional logging to help identify the issue.
Got rid of unused attributes in header file, left over from socket code.  Move the code that is needed to issue HEAD and setup bin element into new method dlna_src_uri_init().  When setting up the bin, check if dtcp element should be used as ghost src pad or soup http src.  Got rid of duplicate code that used to be in dlna_src_setup_dtcp().
Changed comment from c++ style to c style
