The content provider is the first component started with the main process,
which makes it ideal for initiating LauncherAppState

- Seperate search bar height from its top and bottom paddings
- Report this height plus 8dps top and bottom for the widget options
- Use a separate bottom padding to adjust spacing between QSB and
the workspace
- Add tests to verify the height of the search bar in both normal and
tall modes (ran on Nexus 6, 7, and 10)

There is a race condition that occurs primarily (maybe entirely) with
Android Auto, it seems because they hijack the Home intent or something
similar. I'm not exactly sure how Android Auto works, but if I pair my
phone with the Desktop Head Unit (car dashboard emulator), I can repro
the NPE fairly easily by simply force closing Android Auto and then
disconnecting my phone from the DHU. If I don't force close Android
Auto, then pressing home launches Android Auto or other apps that I
assume handle some custom intent, such as Car Home Ultra, instead of
normal Home intents such as Launcher3/Google Now Launcher. So I think
what's happening is that, when the phone is disconnected from the car,
Android Auto restores and launches the real home intent (Launcher 3)
around the same time that it destroys the previous home intent
(Android Auto, Car Home Ultra, etc.). This could cause the NPE if both
intents are actually Launcher 3, as is the case when Android Auto is
already closed, because mWorkspace is set to null in
Launcher#onDestroy() (something like onNewIntent() --> post() called
--> onDestroy() --> post() runs). This is consistent with the fact
that I can guarantee a repro if I use postDelayed() instead of post().
Long-winded explanation aside, I think this fix is safe, especially
since we already have a null check for mWorkspace in onNewIntent(),
just not inside the post().

This ensures that the QSB widget options are set correctly the first
time they are used.

The problem was due to a race condition between removing a prebound
widget view from the drag layer and adding the same view to the
workspace upon dropping it; if you let go of the widget immediately
after picking it up, the latter happened before the former.
Specifically, the flow was: long-click a widget --> drop --> remove
the view from the drag layer if it's not null (it is, so nothing
happens) --> the view is finally bound/inflated and added to the drag
layer --> add the view to the workspace --> already has a parent.
There are actually 2 problems here: one is that the bind/inflate is
asynchronous, and can therefore happen after dropping the widget view
being inflated, and the other is that the view is added to the
workspace even though the transition has barely started (we usually
ignore drops if the transition is less than half complete). It turns
out that this second problem was also due to a race condition, this
time between dropping a widget or app onto the workspace and calling
LauncherStateTransitionAnimation.dispatchOnLauncherTransitionStart().
If the drop happened before the dispatch, as in the case of the
crash, then the drop was accepted because the transition progress was
still 1.0 from the previous transition.
I fixed the first problem by removing the drag layer widget view
in Launcher where it is potentially used instead of Workspace. And I
fixed the second problem by setting mTransitionProgress to 0 in
Workspace.onLauncherTransitionPrepare().
I also added some debugging logs.

The search bar can now be be normal or tall. When it is set to tall,
the hotseat and page indicators move down so that the workspace isn't
compressed quite as much.

Previously, it was only called at the start and end of the transition;
now it is called as the animation interpolates. Specifically, a dummy
ValueAnimator is played alongside the transition animation and calls
dispatchOnLauncherTransitionStep() as it goes.
One place where this is important is in Workspace, where
mTransitionProgress is used to determine things like whether the
workspace should accept a drop - hence the bug that caused apps dragged
from All Apps to vanish when dropped before the transition ended.

Using itemId instead of generating a new id for each item. This is because
if the process gets killed, View.generateId will get reset but we will still
receive the generated item id map in onRestoreInstance. This will cause
conflicts with newly generated item ids.
We wrap all the generated homescreen views inside a single sparse array. This
ensures that we do not cause any conflict with dynamically generated views in
other parts of the UI.
