When all audio tracks have been disabled and the mixer is running idle before the output stream is placed in standby,
the mixer sometimes fails to write to the output stream on time to avoid underrun.
This is because the sleep period used to wait before the next write to output stream is too close to the actual buffer duration.
In fact this sleep time is not critical as if we write too early to the output stream, the kernel driver will wait for free buffers
from the audio DSP DMA and we will sleep anyways.
The fix consists in dividing the calculated wait period by 2 to increase the margin.

This is necessary to allow creating and enabling an effect attached to a particular player
session before the playback is started. As a matter of fact, the implementation of the mediaplayer
does not create the AudioTrack before playback starts.

When a temporary container is created, its existence should be
ephemeral. However, if there is an error that causes system_server to be
killed during the process of creating a finalized ASEC, delete the stale
containers on the next start-up of system_server.

getTempContainerId() would always return "smdl2tmp1" unless you had
MAX_CONTAINERS number of SD card SDKs, because of an array sort that put
all the zeros at the beginning.
Switch from trying to find a hole in the series of numbers to just
getting a number that's one larger than the previous. This reduces the
algorithmic complexity and the memory requirements.

Refactored the input reader so that each raw input protocol is handled
by a separate subclass of the new InputMapper type. This way, behaviors
pertaining to keyboard, trackballs, touchscreens, switches and other
devices are clearly distinguished for improved maintainability.
Added partial support for describing capabilities of input devices
(incomplete and untested for now, will be fleshed out in later commits).
Simplified EventHub interface somewhat since InputReader is taking over
more of the work.
Cleaned up some of the interactions between InputManager and
WindowManagerService related to reading input state.
Fixed swiping finger from screen edge into display area.
Added logging of device information to 'dumpsys window'.

The type of the cmd, cmdSize and *pReplySize parameters of the effect control interface command()
function have been modified from int to uint32_t. This is more consistent with their role.

this situation happened when the last buffer needed to be resized
(or allocated, the first time). the assumption was that the buffer
was in use by SF itself as the current buffer (obviously, this
assumption made no sense when the buffer had never been allocated, btw).
the system would wait until some other buffer became the "front" buffer.
we fix this problem by entirely removing the requirement that the
buffer being resized cannot be the front buffer. instead, we just
allocate a new buffer and replace the front buffer by the new one.
the downside is that this uses more memory (an extra buffer) for a
brief amount of time while the old buffer is being reallocated and
before it has actually been replaced.

Add a method to let a properly permissioned app directly
manipulate the user activity timeout. We should come up
with a better API for this, but this is for a last minute
power manager hack to turn off the screen sooner after a
phone call ends.

SensorService now correctly sends the last known
state of a sensor as soon as a new connection is made.
This fixes the issue where, for instance, an application
could wait a long time before getting the light or proximity
sensor initial state.

We can't use Parcel.writeValue() to write the ParcelFileDescriptor, otherwise
it leaks when returning the value to the caller (the flag gets lost). Change
the way DropBoxManager.Entry gets serialized so that it uses a bit of its own
flags value to track whether the data is a byte[] or a ParcelFileDescriptor.
Modify the dropbox unit test to add extensive checking of Entry serialization
and deserialization under various circumstances, and to include a regression
test to ensure that FD leaking doesn't happen.

Added methods for audio effects management by audio policy manager.
- control of total CPU load and memory used by effect engines
- selection of output stream for global effects
- added audio session id in parameter list for startOutput() and stopOutput().
this is not used in default audio policy manager implementation.
Modifications of audio effect framework in AudioFlinger to allow moving and reconfiguring
effect engines from one output mixer thread to another when audio tracks in the same session
are moved or when requested by audio policy manager.
Also fixed mutex deadlock problem with effect chains locks.

Fixed the following problems in audio effect volume control in AudioFlinger:
- Make sure that the volumes returned by EffectChain::setVolume_l() are correct even is
no change is detected since last call
- Do not use isEnabled() to validate volume control but mState >= ACTIVE instead as the volume control
must be also active in STOPPING and STOPPED states.

if the location provider does not exist. Instead use the same behavior
as if the provider were disabled in settings
(return false for isProviderEnabled and null from getLastKnownLocation).
This eliminates for a lot of exception handling around some simple
queries to the location manager.

Added several new coordinate values to MotionEvents to capture
touch major/minor area, tool major/minor area and orientation.
Renamed NDK input constants per convention.
Added InputDevice class in Java which will eventually provide
useful information about available input devices.
Added APIs for manufacturing new MotionEvent objects with multiple
pointers and all necessary coordinate data.
Fixed a bug in the input dispatcher where it could get stuck with
a pointer down forever.
Fixed a bug in the WindowManager where the input window list could
end up containing stale removed windows.
Fixed a bug in the WindowManager where the input channel was being
removed only after the final animation transition had taken place
which caused spurious WINDOW DIED log messages to be printed.

- Fixed crash when deleting an effect chained before an effect having volume control
- Changed EFFECT_FLAG_VOLUME_CTRL to implicitely include EFFECT_FLAG_VOLUME_IND
(not need to set both in effect descriptor).
- Volume control changes from one effect to another if needed according to effect enable state
- EFFECT_CMD_SET_VOLUME is only sent when their is an actual change in volume
