This adds a new API with the activity manager to find out about movement between
activities. For my sanity, the old IActivityWatcher is now renamed to
IActivityController, and the new activity movement interface is named
IActivityWatcher.
This changes the search manager itself to use the new API to manage its state.
Note that there are still problems when going back to the search dialog after
it was hidden -- the suggestions window no longer appears until you explicitly
dismiss and re-show it.
Details:
- Add a new SearchDialogWrapper class that makes sure
all access to the SearchDialog is run one a single thread
other than the main ServerThread.
- Don't save/restore seach dialog state in Activity.
This resulted in lots of calls to the SearchManager
throughout the life cycle of all activities, for
the questionable benefit of restoring the search dialog
in a few cases.
- Remove search UI state save/restore, and the isVisible()
method from SearchManagerService. They are no longer used,
and were tricky to implement since they return values from
the search UI thread to the service.
- Handle configuration changes in searchDialogWrapper instead
of calling through from Activity.

TODO:
- Activity.performPause() calls stopSearch(). This call may not happen
until the new activity has been started. If the new activity starts a
search immediately, this search could be cancelled by the old activity's
call top stopSearch().
Add small unit test for NeighboringCellInfo in AndroidTests. The old telephony unit test directory, CoreTest/android, is marked as deprecated in AndroidTestHowto.

+ Now rechecks the cached IBinder each time the wrapper is used, and if it's
still null (i.e. the BackupManager was constructed before the system service
came up) it's refetched. This lets even system code cache a single
BackupManager instance and just keep making calls through it without worrying
about interactions with the life cycle of the backup service.
+ Added a static dataChanged(packageName) method as a convenience for code that
needs to indicate that some other package needs a backup pass. This is useful
even for third party code in the case of multiple packages in a shared-uid
situation.
Otherwise, the different text measurement methods produce slightly
different results and cause the text to show different results for
Spanned vs. non-Spanned source strings.
Bug 1837826
Applications can now declare that they support small, normal, or
large screens. Resource selection can also be done based on these
sizes. By default, pre-Donut apps are false for small and large,
and Donut or later apps are assumed to support all sizes. In either
case they can use <supports-screens> in their manifest to declare
what they actually support.
This change amends the doRestore() / onRestore() interface to backup agents to
provide the integer android:versionCode of the app that stored the backup set.
This should help agents figure out how to handle whatever historical data set
they're handed at restore time.
They were only static because of a now removed restriction that
only activity contexts could instantiate SearchManager.
This only changes hidden APIs, but all users of the changed methods
must be updated to use them non-statically before this is submitted.
