Clean up return code types

Browse source 
* Remove dds_return_t / dds_retcode_t distinction (now there is only
  dds_return_t and all error codes are always negative)

* Remove Q_ERR_... error codes and replace them by DDS_RETCODE_...
  ones so that there is only one set of error codes

* Replace a whole bunch "int" return types that were used to return
  Q_ERR_... codes by "dds_return_t" return types
