Clip editor: sort order for dopesheet channels

Supported sorting by name, longest tracked segment and total tracked frames.

Internally tracks are stored in Tracking datablock, but sort order is
a clip editor space property and sorting happens on clip editor draw.
If there's no dopesheet opened with different sort orders it's not
a problem due to re-sorting wouldn't happen.

Also fixed draw issue of tracked segments introduced in previous commit.
