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.

Currently the media scanner does not create database entries for directories
unless they contain a file that is scanned.
Fixing this so we provide a consistent view of the world to MTP.

Set resource config_mtpReserveSpaceMegabytes to number of megabytes to reserve.
If MTP has dedicated storage this value should be zero, but if MTP is
sharing storage with the rest of the system, set this to a positive value
to ensure that MTP activity does not result in the storage being
too close to full.
