A regression was introduced by the change enabling per device volume:
music volume will not be completely silenced even if volume is shown at 0.
The problem is that when media volume goes to zero, silent mode is entered and
AudioService sends one message per stream/per connected device to the audiosystem
handler to mute volume on each stream. As those messages were sent with the
SENDMSG_NOOP attribute, some of them where lost.

Inserts of directories can be done in bulk as long as they're inserted before
the files contained within. Extend MediaInserter to accommodate giving priority
treatment to directories.
Bulk deleting of entries can be further sped up (by a factor of ~3 in my tests)
by deleting entries in database order. Switch the file cache to use
LinkedHashMap instead of HashMap to allow iterating over the cache in database
order. Also use bindArgs to allow for better caching of sql statements.

Add support for modifying the playback rate of a MediaPlayer
by altering the sample rate of its AudioTrack.
The playback rate is expressed in permille, where 1000 is the
playback at normal speed.

The use case for master mute is to toggle it on and off from a
KEYCODE_VOLUME_MUTE event, so this was unnecessary and prevented unmuting
in certain cases

Unconditional delete for raw pointers.
Use "if (sp != 0)" not "if (sp.get() != 0)" or "if (sp != NULL)".
Use "if (raw != NULL)" not "if (raw)".

Deleting entries from the database in bulk greatly speeds up the media
scanner in some cases; removing 31k entries used to take about 2 hours,
now it takes about 15 minutes.

Other:
- add a comment to nextUniqueId
- made ThreadBase::mId const, since it is only assigned in constructor.
