Add a timeline view for packets, with the timing data used to generate the display

taken from the timing analysis done in the wlan_radio dissector. QT only.

The timeline background is light gray, white for packets displayed in the packetlist,
and blue for the currently selected packet. Packets are coloured according to the
colouring rules foreground colour. The timeline can be zoomed with controls on the
toolbar.

At higher zoom levels the duration (NAV) field is plotted as a horizontal line to the
right of a packet.

The height of a packet in the timeline is proportional to the RSSI.

The bottom half of the packet is only shown if it matches the display filter.

Todo:
Auto detect TSF timing reference point (start/end of packet)
Add a scrollbar
Add a ruler showing time
Improve handling of focus.
Do not display NAV for packets with bad FCS.
Show related packets graphically
Different Y axis modes
- bandwidth/channel use display
- different transmitters per line
- background color from coloring rules
Live capture support
