Properly resolve the userId when running on concurrent multi-user
In concurrent multi-user mode, `showSoftInput` and `hideSoftInput`
derive the userId from the binder caller's user id. However,
this fails when the caller is the system user (user 0), especially
when `startInputOrWindowFocusGained` was previously called by the
system user while while passing another user id for the `userId`
parameter.
This changelist modifies `showSoftInput` and `hideSoftInput` to
instead resolve the userId from the display owner within the
`client` parameter.
The long-term solution involves implementing per-user and
per-window IME binding in IMMS, and adding a `userId` parameter to
both the showSoftInput and hideSoftInput methods (this will allow
apps started by system user to specify another user when invoking
these two methods).
This changelist shouldn't introduce any breakage on phones or tablets.
