Revert 37009 - Adding geolocation data provider infrastructure to Chrome.
Rolling back as it seems to have broken the Mac build

These files are lifted from gears: http://code.google.com/p/gears/source/browse/trunk/gears/geolocation/

NOTE this is a direct copy of gears files; subsequent edits will be made to bring them into chrome style and add to gypi files and so on.

BUG=11246
TEST=None (just adding placeholder files; tests will follow in next change)
