Revert "use utf8_length() instead of local function, isValidUtf8()"
This reverts commit 1a8b6c2

Reason for revert: utf8_length handles a slightly different range than
the checkjni code, so it's possible for a given string to pass the
utf8_length check, but then fail the jni  check.

Correct the target app token for input method window

The root cause is:
There is a defect in window manager service: When a new
activity that can be ime target is added into window manager
but the Z order of input method window don't need to be
changed, then the target app token of input method window
would not be updated to new one. This defect may cause that
the layer of input method window is calculated incorrectly.

The solution:
Correct the target app token for input method window.

Two REMOVE_PROVIDER messages caused by race condition.

Fix a bug in unstable ContentProvider.
IllegalStateException: ref counts can't go to zero here: stable=0 unstable=0
IllegalStateException: unstable count < 0: -1

There is a race between main thread and background database thread. Main thread
is responsible for handling the REMOVE_PROVIDER message. Database thread starts
insert or query request again and again. acquireProvider in db thread will often
snatch provider from the jaws of death, sometime it fails to remove REMOVE_PROVIDER
which is already fired out from MessageQueue. But completeRemoveProvider in main
thread gets suspended when trying to execute the critical section. If db thread
released the provider before main thread resumes the execution, then two
REMOVE_PROVIDER messages will be executed.

services: don't clear wallpaper when SystemUI
disconnects.

When we restart SystemUI (or the user), sometimes
the wallpaper would get cleared. This patch just
captures its originating component and
if that is our SystemUI component, ignore the event.
