Second try for:

http://src.chromium.org/viewvc/chrome?view=rev&revision=39374
Initial Geolocation implementation
Adds IPC plumbing.
Adds Infobar buttons for requesting permission

This change specifically:
ui_test_utils::WaitForAppModalDialog registers for listening to notifications too late, i.e., after the dialog had been triggered.
Exposes AppModalDialogObserver so that we can register, trigger the dialog, then wait for it.
