Disable touch while using the stylus (Galaxy Note)

Android 4.0 cannot form multitouch events from multiple input
devices. So it is not possible to report one touchpoint from the
stylus position and, at the same time, another touchpoint from a
finger touch. Instead, when a new input device starts up the currently
active input is cancelled. This is highly undesirable while writing
with the pen.

The easiest solution is to ignore non-stylus touch events while the
stylus is within range (hovering) of the touchscreen. For example,
N-trig digitizers implement this in hardware. But wacom digitizers do
report pen data simultaneously with touch data. This patch disables
(non-stylus) touch input within 50ms of stylus data. On my Galaxy
Note this is necessary to make stylus input usable.

Insufficient ProcessRecord cleanup when persistent process is killed

When persistent process with Service restarts, ActivityManagerService
does not reset ProcessRecord#hasClientActivites to false
(because ProcessRecord of persistent process is continued using
after killing).

It disturbs updating LRU list in ActivityManagerService, and then,
when new process calls ActivityManagerProxy#publishContentProviders,
SecurityException happens because of no entry in the list.
