There turn out to be two distinct bugs leading to runtime restarts.
The first, dating from at least Android 3.1, is that following certain kinds
of app crashes we properly clean up the drag-state bookkeeping, but aren't
prepared in the case of the drag-target timeout clock firing with a now-
null drag state in effect. We now catch that edge condition and don't NPE
(and note that there was already similar code around the separate timeout
when an app is *starting* the drag process).
The second bug is that some new-in-ICS code in the input channel management
wasn't prepared for certain cases where the current touch window could have
become unusable and its input channel torn down summarily in the case of the
aforesaid app crash during drag. The code now makes sure that there really
is an input channel that needs to be flushed / cancelled prior to attempting
that operation.

Currently legacy VPN only works on IPv4, and it should always
turn down when the addresses are changed. It assumed that the
interface will be brought down and up, so the event can be
detected via interfaceStatusChanged(). However, the assumption
was incorrect and the event is actually driver-dependent. To
fix this issue, ConnectivityService now tells VPN that the
interface is down when resetting IPv4 addresses.

Teach NetworkStats about "counter sets" coming from kernel, and use
them to track usage in foreground/background. Add AID_NET_BW_ACCT to
system_server so it can control counter sets.
Move to composite key of NetworkIdentitySet, UID, set, and tag when
recording historical usage. Persisting still clusters by identity,
since that is heaviest object.
Request async stats poll during systemReady() to bootstrap later
delta calculations. Reset kernel counters when UID removed. Update
various tests.

Bug: 5161854
The InputDispatcher contains code to recover from ANRs more quickly
when the user touches a different application. When triggered,
it sets mNextUnblockedEvent to the next event it should dispatch
(to the next application). All prior events are dropped.
This change fixes a bug where mNextUnblockedEvent could potentially
never be reset back to NULL if the inbound queue was drained
for some reason.

Replace mDisposeAfterWriteToParcel with code that takes advantage
of the standard Parcel API support for releasing resources after
writing a Binder reply.
This change makes it less likely that InputChannels will leak

AudioManager.isWiredHeadsetOn() should not require permission MODIFY_AUDIO_SETTINGS.
Remove permission checks on all getters in audio policy manager as permission enforcement
is really usefull for setters.
Also deprecate AudioManager.isWiredHeadsetOn() which name and implementation are deceptive.

Don't clear slot data when slot is no longer in use.
The kernel will not resend absolute slot values if they are
unchanged, even if the slot was previously marked unused.
Because the protocol is stateful, this could cause problems if
evdev drops events (marked by SYN_DROPPED) since we cannot
query the initial values of the slots, but there's nothing
we can do.

Before this change, CPU and memory usage for an audio effect were
registered and checked against the limit by audio policy manager
upon effect instantiation. Even if an effect was not enabled
it would prevent another effect to be created if the CPU load budget
was exceeded, which was too restrictive.
This change adds a method to register/unregister CPU load only when
an effect is enabled or disabled.
It also adds a mechanism to place all effects on the global output mix
in suspend state (disabled) when an effect is enabled on a specific session.
This will allow applications using session effects to have the priority
over others using global effects.
Also fixes some issues with suspend/restore mechanism:
- avoid taking actions when an effect is disconnected and was not enabled.
- do not remove a session from the suspended sessions list when corresponding
effect chain is destroyed.
