There is now an API, which is used for task switching.
Also improved how we handle rotation animation when we can't take a
screen shot, to cleanly revert to the old freeze behavior. This removes
the need to special case the emulator.

We were setting ACCELEROMETER_ROTATION to 0 before putting
in the proper USER_ROTATION value, and PhoneWindowManager's
content observer would eagerly rotate the screen to the last
locked orientation before re-rotating to the updated locked
rotation.
Now we set USER_ROTATION first. Additionally, the
content observer is now the only place we set
mUserRotation{,Mode} (previously we would race with it in
setUserRotationMode()).
