kinaba:
Since the huge IME refactoring patch (part 6 of 6) only works fine with
ibus-1.5, I'll upgrade ibus once the huge change gets LGTM from you. However,
since we don't have a good way to synchronize Chrome and Chrome OS (= ibus in
this case) revisions, I would like to do ibus upgrade in the following way:

1. Submit this CL today. This CL has many corner case issues, but with this CL,
Chrome can interact with ibus-1.5 correctly in major cases. This CL is nop when
ibus-1.4 is in use.
2. (Get your LGTM for the huge CL. It will likely take a few days.)
3. Unmask ibus-1.5.
4. Submit the huge CL.

After step #3, Chrome OS's build_image script might pick up a Chrome revision
without the huge CL, but it will somewhat work if #1 is submitted.

You mean value.string_list_value[0]? The vector is already rotated here.

LGTM on patch set 2, and the plan in the first comment.
