Stéphane Cerveau c28e7d928d dash: move parser nodes/types to separated files
Rename GstMpdClient to GstMPDClient and use GObject model.

Move nodes to file from gstmpdparser.c:
- GstMPDRootNode
- GstMPDBaseURLNode
- GstMPDUTCTimingNode
- GstMPDMetricsNode
- GstMPDMetricsRangeNode
- GstMPDSNode
- GstMPDSegmentTimelineNode
- GstSegmentTemplateNode
- GstMPDSegmentURLNode
- GstMPDSegmentListNode
- GstMPDPeriodNode
- GstMPDRepresentationNode
- GstMPDsubRepresentationNode
- GstMPDAdaptationSetNode
- GstMPDContentComponentNode
- GstMPDSubsetNode
- GstMPDProgramInformationNode

Move types to gstmpdhelper from gstmpdparser.c:

- GstURLType
- GstDescriptorType
- GstSegmentBaseType
- GstMPDMultSegmentBaseType
- GstMPDRepresentationBaseType

Cleanup naming when possible.
