This CL a logical revert of a previous CL [1], which separated Java
files into common ones and overridable ones.  Now that that overriding
concept is no longer used, there is no need to keep having separate
directory structure.

This CL introduces a custom intent action for apps to ask AOSP Keyboard to
close its software keyboard with guarding it with a signature-protected
permission.

Any app that is signed with the same signature as AOSP Keyboard can have
the following line in AndroidManifest.xml

  <uses-permission
          android:name="com.android.inputmethod.latin.HIDE_SOFT_INPUT"/>

to request AOSP Keyboard to close its software keyboard as follows.

  sendBroadcast(new Intent("com.android.inputmethod.latin.HIDE_SOFT_INPUT")
          .setPackage("com.android.inputmethod.latin"));

Test: Manually verified with a test app.

In order to avoid layering violation, LocaleList needs to be moved from
android.util package to android.os package [1].  This CL follows up that
package change.

No behavior change is intended.

LatinIME checks hardware keyboard presence and software keyboard
visibility to decide whether to start full screen mode.
This doesn't work well with the recent update on "Show input method"
(Bug: 22517687, Id4d332e3909590c68345e).

On the first tap, software keyboard is not shown and hardware keyboard
is connected; so full screen mode is not started. However,
onEvaluateInputViewShown may return true ant software keyboard may be
brought up.
In this care, on the second tap, software keyboard is visible so full
screen mode will be started regardless of hardware keyboard presence.

This CL checks onEvaluateInputViewShown to decide whether to start
full screen mode.

We want to expose Serbian (Latin) layout as "sr-Latn" to the system,
while our internal logic may not be ready to deal with "sr-Latn" yet.

As a temporary workaround, we remap "sr-Latn" into "sr_ZZ" for our
internal use.

This reverts commit 3e267026.

It turns out that the behavior change in libcore was unintentional, and
it was already fixed [1].  Let's revert our workaround back to see if
the existing code is compatible with N.

This is a follow up CL to the previous CL [1], in which we started
calling Window#setNavigationBarColor(int) when the window visibility is
changed.

One thing we missed is that calling Window#setNavigationBarColor(int) on
KitKant or prior devices would result in a runtime crash.  Hence with
this CL we do not call that method unless the OS version is N or leter,
because specifying Color.TRANSPARENT would make sense on N+ devices.

With this CL, LatinIME switches the current subtype from its enabled
subtypes based on the first locale in EditorInfo#hintLocales.

This functionality is still experimental, and will be triggered only
when EditorInfo#hintLocales is specified by the application.

Starting in N, we are going to have new APIs to officially support the
situation where apps need to run before the user has unlocked their
device for the first time.  For IME developers those APIs would be
important not only because IMEs developers may want to support other
apps that support that feature but also because IMEs developers have
already needed to pay attention to the same situation where the IME is
running so that the user can enter the initial password (e.g. for an
encrypted device).

Bug 11270326 is a perfect example of this scenario.  Now we can disable
settings-key until the device is unlocked by using the new API when
running in Android N devices.

The opaque navigation bar guard view does not make much sense when the
IME does not show software keyboard at all.  LatinIME does not show
any UI when the hardware keyboard is connected.

With Iea77915ecc55eedaf19899e72c44f704ba9d852c, input method can change
the navigation bar visibility.  This CL changes navigation bar invisible
when the hardware keyboard is connected.

When upgrading to a new version of APK we may find that the stored Emoji
category ID is no longer applicable. For example it happened when we
brought in the new Unicode 8.0 Emojis.

Also restore the "Symbols" emoji category on pre-kitkat devices which
was accidentally dropped when bringing in Unicode 8.0 Emojis.

Change the way we decide whether we want to show on-screen keyboard by
not only paying attention to modifiers, but also keeping track whether
the key sequence started in the right state.

We are still misfiring if user presses a non-modifier key and then our
modifier hot-key, but such sequence is unlikely. Given the fact that we
do not want to store too much state I believe this deficiency is
acceptable.

If user has not used emojis we should not bring recents emoji tab on the
first invocation of the on-screen keyboard as it is confusing to see an
empty tab.

We will still be showing recents tab even if it is empty if user
actively switched to it when using on-screen keyboard.

Check to see if setup wizard is running before showing toast to
inform user that a download was started. Note that this will only
affect the device owner; when adding new users later, the toast
will still appear. (The USER_SETUP_COMPLETE flag is hidden from
the SDK, while DEVICE_PROVISIONED remains available.)

FileUtils is being used for other non android projects
and hence breaks when built. Instead use the log statements
at caller to record Log.e messages. Hence there is no side
effect here.

This will ensure that a new (or upgraded) keyboard instance will know which
dictionaries are available for download so it requests missing dictionaries.
In addition, we increment the database version number to ensure upgrades of
existing Fava instances start with a clean slate.

The initial reloadTextCache() operation needs to read 1k characters, and it
could be slow on low-end devices. Also, the initial load is not blocking key
strokes, so it can take a little longer.

1. Add mechanism to detect a slow or non-resonsive InputConnection (IC)
2. When IC slowness is detected, skip certain IC calls that are known
   to be expensive (e.g., getTextAfterCursor).
3. Similarly, disables learning / unlearning on a slow IC.
4. IC slowness flag is reset when starting input on a new TextView or
   when a fixed amount of time has passed.

Note: These are mostly temporary workarounds. The permanent solution is
to refactor RichInputConnection so that it is less sensitive to IC
slowness in general.

Users rarely tap on committed words, and the cost of sending the spans back
through the input connection, back and forth to the target app, is too high.

This is causing issues we can't deal with in a safe and timely manner.
Furthermore, users who need downloaded dictionaries already have them by now.
