My previous change to speed up the time the IME is dismissed was
fundamentally flawed. That change basically switched the order
the application called the input method manager service from doing
startInput() and then windowGainedFocus(), to first windowGainedFocus()
and then startInput().
The problem is that the service relies on startInput() being done
first, since this is the mechanism to set up the new input focus,
and windowGainedFocus() is just updating the IME visibility state
after that is done. However, by doing the startInput() first, that
means in the case where we are going to hide the IME we must first
wait for the IME to re-initialize editing on whatever input has
focus in the new window.
To address this, the change here tries to find a half-way point
between the two. We now do startInput() after windowGainedFocus()
only when this will result in the window being hidden.
It is not as easy as that, though, because these are calls on to
the system service from the application. So being able to do that
meant a fair amount of re-arranging of this part of the protocol
with the service. Now windowGainedFocus() is called with all of
the information also needed for startInput(), and takes care of
performing both operations. The client-side code is correspondingly
rearranged so that the guts of it where startInput() is called can
instead call the windowGainedFocus() entry if appropriate.
So... in theory this is safer than the previous change, since it
should not be impacting the behavior as much. In practice, however,
we are touching and re-arranging a lot more code, and "should" is
not a promise.

This adjust various paths through InputMethodManager so that the flow
in switching focus from one application to another is cleaner, resulting
in less work being done, resulting in it being able to happen quicker.
Some of the changes here avoid doing stuff when not needed, such as when
we are told to unbind but are not currently the active input. A big part
is also a change to the flow when a window receives input. Previously
this would first do a checkFocus() which would tell the input method to
switch focus to whatever view has focus in the window, followed by the
windowGainedFocus() call telling it the window had gained focus. This
would result in extra work because the input method service would first
handle the focus switch, seeing the IME is currently displayed, so the IME
would remain up and reset its focus to the new view. The app would
immediately then tell it about the window, causing the service to find out
the IME should be hidden and telling the IME, but the IME couldn't hide
itself until it had first take care of switching its input.
There is the definite potential of this breaking IME showing/hiding in
cases depending on the order things may be relying on them to happen. I
haven't seen any problems with a brief trip through the UI.

Don't consider a window as a candidate for the top fullscreen window
if it is not going to be a candiate for layout.
This fix does not include the change to ignore app tokens that are
hidden. This causes problems in some dialogs that stay hidden until
their app is ready to display, but need to perform a series of relayouts
during that time to get to the right size. Dropping this part of
the change still (mostly?) seems to allow us to avoid the bad states.

Also relaxed the settle time constraints a little bit.
With this change, a rotation proposal will always be
advertised within 500ms even if the device is still shaking
around.

This fixes a bug where the device fails to lock when DevicePolicyManagerService
requests the device to be locked and the screen was off because the user hit
the power button.
The change allows DPMS to directly invoke screen lock, bypasssing the screen state.

Don't consider a window as a candidate for the top fullscreen window
if it is not going to be a candiate for layout.
Also don't consider windows a candidate for layout if their app token
is hidden. This fixes a transient state where we are preparing to
unhide the window but have not done so yet.

...rotating to landscape
When doing spell checking in the same process as the spell checker, we
need to make sure it is still done asynchronously.
Putting this in I noticed quite a few threading issues in this code, so
I also addressed those (which became very obviously a problem with the
async stuff here now).
Also tweaked the service side to run spell checking at background priority.

We need to work more like before in determining whether the menu
key is needed -- in some cases look back in the window list to
determine this if we don't know the value from the current window.
This requires adding a new private flag indicating whether the
compat menu state is known for a window, which is set by
PhoneWindow as part of its existing process of computing the flag
for its own windows.
Now we can have a new API on WindowState to determine the value
of this flag for a window, which if needed walks back in the window list
to find a window the value is known for (or stops at what the policy
has determined is the top full-screen window, so we stop like we used
to at things like the lock screen or the bottom of an application).

Our typical touchscreens are now good enough that we don't need the
touch slop to be as large as it once was. Lower it to increase
responsiveness while scrolling.
Move the touch slop constant to the config resource
config_viewConfigurationTouchSlop so that it may be more easily
tweaked in device-specific overlays.
