ActivityThread: Avoid creating duplicate handlers and reuse mH

sMainThreadHandler is used for notification of changes in
SharedPreferences and refers to a new instance of Handler instead
of the existing instance, mH, of the ActivityThread. Fix to reuse
existing handlers associated with main looper.

VibratorService: Fix to ensure actual delay in a vibrate pattern

delay might timeout early as value of duration isn't updated
correctly in the loop, should the wait be interrupted, to reflect
the elapsed time. Fix is to update duration in the loop.

Avoid system_server crashing due to mac address is null

It's possible that the mac address is null (getMacAddress() of WifiNative.java).
In this case system_server will crash like:

E AndroidRuntime: *** FATAL EXCEPTION IN SYSTEM PROCESS: WifiWatchdogStateMachine
E AndroidRuntime: java.lang.NullPointerException
E AndroidRuntime:        at android.net.arp.ArpPeer.<init>(ArpPeer.java:57)
E AndroidRuntime:        at android.net.wifi.WifiWatchdogStateMachine.doArpTest(WifiWatchdogStateMachine.java:866)

Check the mac address before parsing to avoid crashing.

WifiStateMachine: ignore auth-fail event during WPS connection

Disregard auth failure events during WPS connection. The EAP sequence is
retried several times, and there might be failures (especially for wps pin).
We will get a WPS_XXX event at the end of the sequence anyway.

Without this change, the SupplicantStateTracker class will disable
the WPS network we are connecting to after 2 failed authentication events.
Then, even if WPS succeeds, we will never connect to the selected network.

Protecting more views from (bad) MotionEvents

When handling MotionEvents, the method findPointerIndex can return -1
if the current pointer id can't be translated to a pointer index.
Some views are not handling this, which will lead to an out-of-
index crash. In 2585e9b there were checks added, this change adds
some more.

Fixes relative time formatting issue for dates in future

All variations of getRelativeTimeSpanString() now properly handle dates
that are in the future. Prior, the version used by
getRelativeDateTimeString() would occasionally show the time instead of
a date when the future date was the same weekday as the current weekday.
This resulted in the time output being duplicated, eg.: "11:23, 11:23"

Make setCaptureRate locale safe

Dont use the default String.format in setCaptureRate as it is both
locale unsafe and less efficient than regular string concatenation
in this case.
