BigPicture lazy loading
This CL covers the followign so far:
- after inflation: read the image header (if we can) and set a placeholder or set the full image (if there is no header)
- on expansion: read the full image and set it on the ImageView
- on collapse: free the full image and set the placeholder again
- throttle the jobs started by the expand/collapse calls
Gated by the statusbar flag bigpicture_notification_lazy_loading.
