Move all geofencing code into its own module separate from geolocation.

Why does this file show as a new add instead of a move with minor edits? Try
uploading with a smaller similarity threshold e.g.:
git cl upload --similarity=30

[Marijn Kruisselbrink, 2014/08/06 18:27:18]

Because this is a new file? But okay, it does make sense to use lower similarity
to make it appear a modification of the push api code.

FYI: ScriptWrappable will soon no longer require a destructor -
