2.5

Fixes in view2d:

- mask/slider rects were calculated wrong 1 pixel (was overlapping)
- found bug with outliner stretching on area-edge-dragging. It required
  an extra mapping of the 'cur view' via mask to actual region.
- added v2d sanity check for uninitialized v2d's
- removed cruft in do_versions for headers (gets catched with above)
- added header-view2d-initialize function, for new-space calls

Fixes in areamanager:

- fixes in 'new space' for time/outliner/view2d
  (unfinished)

For Joshua:

- Making time window higher shows it doesn't update 'cur'. Not sure
  what kind of v2d flag should be checked or set?
