Encapsulate private data and prepare for port to GObject
---
Changes in v2:
- Fixed leak of priv by using 1-element array trick
- moved unrelated change
- added red_channel_client_get_pipe() and red_channel_client_is_mini_header()
to avoid accessing RedChannelClientPrivate from DisplayChannelClient.
