Fixes http://b/2650378

On entering the selection screen, don't add the system language in addition
to other selected languages.

Also add a summary text in the input language list for languages with
a dictionary so that users don't feel cheated when they pick a language
that doesn't happen to have a dictionary. Remove greek as it isn't an
extension of the QWERTY keyboard.

Move java code to a different directory so that the unbundled
version doesn't try to compile the native code again.

Bug: 2488167
Don't show ko, ja and zh languages in the list.

Remove a debug println.
Add alternates_for_g to the keyboard for it to work on turkish. This
  must have not gotten merged from donut.

Due to the addition of input language switching, the auto dictionary
will be re-created very frequently. We need to save it and restore it
during transitions, otherwise the data will be purged too often to be
of much use in the multi-lingual case.

This also fixes the case where a user frequently turns the phone off/on.
Auto dictionary data was not being saved in those situations either.

The dictionary will probably never grow too large since most of the
frequently used words will be moved to the user dictionary any way.

Also, now the input locale is different from the display locale, so
save the input locale in the UserDictionary class and insert words
into the user dictionary with the correct locale.

And NPE fix for bug: 2464573

And fix a bug in opening keyboard settings when Voice is not available.

Bug 2417503

New feature to enable fast switching between input languages for
multilingual users. Keyboard settings lets you select a bunch of
languages to switch between from the Latin IME.

Use the Globe icon to toggle between languages.

Needs more work and some layout changes in specialized keyboards.

Also added a Russian keyboard (needs some pixel TLC at the right edge).
