Bug 17059255
Change-Id: I966e9ed00ed75a78c9b4741b7f68bae996442cdf
Add support for building a SoundPool instance and specify
the AudioAttributes.
Remove SRC quality which was never implemented, while leaving
room for supporting it later through the Builder pattern.
Remove stream types.
Update AudioService's use of SoundPool to the new scheme.

- Add new audio restriction layer to app-ops. Restrictions add
additional constraints to audio operations at a stream-level.
Restrictions do not affect the persistable state, and are purely
additive: that is, they can only impose additional contstraints, not
enable something that has already been disabled. Restrictions
also support a whitelisted set of exempt package names.
- Add new audio stream-level checks to app-ops.
- Implement a provisional OP_PLAY_AUDIO suppression to three
java entry points MediaPlayer, AudioTrack, & SoundPool.
- Enhance vibrator api to take stream information as an optional
hint - the constants correspond to AudioManager stream types.
OP_VIBRATE now supports the stream-level restriction check.
- Simplify Vibrator subclasses by adding default implementations
for two .vibrate calls.
- Migrate NoMan's zen-mode control to use the new app-ops
stream-level restriction mechanism.

For storing pointers, long is used in media classes,
as native pointers can be 64-bit.
In addition, some minor changes have been done
to conform with standard JNI practice (e.g. use
of jint instead of int in JNI function prototypes)

SystemServer is currently a monolithic class that brings up key system
services. This change is the first phase of refactoring it to be more
configurable. Specifically, it adds a set of on/off switches used to control
startup of individual services. Future plans include finer grained controls
and a more explicit and consistent startup sequence for these services.

Add combined channel APIs setVolume to AudioTrack, MediaPlayer, and
SoundPool to make later migration easier, and encourage apps to use
that API. The new APIs are @hide for now.

The problem can occur if a sample is started at the same time as the last AudioTrack callback
for a playing sample is called. At this time, allocateChannel() can be called concurrently with moveToFront()
which can cause an entry in mChannels being used by moveToFront() to be erased temporarily by allocateChannel().
The fix consists in making sure that the SoundPool mutex is held whenever play(), stop() or done() are called.
In addition, other potential weaknesses have been removed by making sure that the channel mutex is held while
starting, stopping and processing the AudioTrack call back.
To that purpose, a mechanism similar to the channel restart method is implemented to avoid stopping channels
from the AudioTrack call back but do it from the restart thread instead.
The sound effects SounPool management in AudioService has also been improved to make sure that the samples have
been loaded when a playback request is received and also to immediately release the SoundPool when the effects are
unloaded without waiting for the GC to occur.
The SoundPool.java class was modified to allow the use of a looper attached to the thread in which the sample
loaded listener is running and not to the thread in which the SoundPool is created.
The maximum number of samples that can be loaded in a SoundPool lifetime as been increased from 255 to 65535.
