- no longer use the 5 most significant bits of the source id.
  => As a result all source id encodings have slightly changed

- DstData:
    move compression from the sourceID into the payload,
    add the encoding key used into the payload

- HltDecReports
    add the encoding key to the payload

- HltSelReports
    no changes to the payload

... and move code in HltDAQ into the DAQ namespace (instead of PackedData)

- and propagate it when merging/splitting buffers
- and use it during packing/unpacking

- replace HltRawBankDecoderBase base class with a service and
  standalone utility funtions
- update decoder classes accordingly
- update the IIndexedANNSvc interface so that it can be used instead
  of the HltANNSvc to implement all int->string mappings.
  (as the interface is a 'versioned superset' of the HltANNSvc)
- update encoder and decoder classes accordingly
  NOTE: this included the ExecutionsReportWriter!
- replace use of non-thread-safe Error and Warning with MsgCounter
