Camera tracking: switch dopesheet information to lazy calculation

All operators which changes tracking data now just tags dopsheet as outdated,
actual re-calculaiton of happens only when this information is actually needed
(like on dopesheet draw).

This makes things a bit faster when there's no dopesheet visible in current
screen and also makes it much easier to update dopesheet using dependency
graph.

Also renamed dopesheet_sort_order to dopesheet_sort_method in rna and internal
stuff which makes much more sense and also correlated with naming in
file browser.
