RTP Player: Dialog is nonmodal now and can be called multiple ways

Changes:
- refactored main_dialog handling of telephony dialogs
- RTP Player dialog is nonmodal now and can be left open
- it is possible to issue three actions on RTP Player dialog from other
  dialogs (other dialog have selected set of RTP streams before action)
  - replace - removes existing streams from RTP dialog and shows new set
  - add - adds new set to existing list in RTP dialog
  - remove - remove streams in set from list in RTP dialog
- Sequence Dialog:
  - was modified to hold rtpstream_info_t for RTP streams
  - added Play button
  - VoIP features (RTP Play button, select/deselect RTP stream) are
    disabled after creation and must be enabled. It handles that RTP
Play button is not shown e.g. in TCP sequence show
