Fix deletion of least-recently-used external databases.

The present external database LRU garbage collector mistakenly includes
SQLite temporary files, including those associated with the internal
database, as distinct external databases.  This leads to a number of
problems, including partial deletion of databases and/or their temporary
files and early deletion of databases before the MAX_EXTERNAL_DATABASES
limit is reached.  In short, the present code works only, and
coincidentally, in a single circumstance: when there is an internal
database and _exactly one_ external database.

This fixes the above problem by removing SQLite temporary files from the
list of candidate databases.

Note, the actual bug here is in the android.app.ContextImpl::databaseList
method, which return SQLite temporary files as part of a context's
"database list" instead of hiding them and handling their deletion
internally.  However, since these methods are part of the Android public
API and used by third-party apps, the present fix is implemented in
MediaProvider only.  Should the Context database API be altered, this fix
will be made redundant but remain unharmful.

MediaScanner: Don't delete entries of secondary storage on shutdown

MediaScanner deletes the entries of secondary storage whenever it
is ejected by the user. However, a shutdown also sends this eject
events. This patch ignores the eject event if the system is being
shutdown.

AlbumArt image of songs in the non-primary storage root dir are images in the same dir

MediaProvider will fall back to the image in the same folder of music,
if MetadataRetriver failed to extract the AlbumArt image from those mp3 files.
MediaProvider will only bypass the albumArt image search if the music located
in the root director of the primary external storage. Add this bypass for all
external storages.

Notify change of movePlaylistEntry after transaction ends

When a client asks the Media Provider to rearrange a playlist
the notifyChange callback function is called before the database
transaction is ended resulting in that listeners can't get the
new data when they get the callback.

notifyChange() is called before the database transaction is ended
resulting in that listeners can't get the new data when they get the
callback.

This fix will wait until the database transaction is finished
to do the callback.

Column in log table is not unique

DATETIME was set as primary key but that value is not always unique.
This solution is to remove primary key constraint from column "time"
to avoid SQLiteConstraintException caused in case same DATETIME value
is attempted to be inserted into log table.

Default ringtone cannot be previewed as alarm stream type.

When choosing a ringtone for alarm use by "Android System"
ringtone picker (RingtonePickerActivity), default ringtone is
not played for preview with volume of alarm stream type but
with that of normal stream type.

It is because stream type is not reflected on mDefaultRingtone
instance of RingtonePickerActivity.

"isMediaDatabaseName" API has to return true only if a parameter is database file path.

But it check only prefix with 'external-'.
Media provider uses Write Ahead Logging that makes wal and shm files.
In case of wal and shm files, the API can also return true.
So additionally, the API has to confirm that the file path has '.db' extension.

Fix logic that delete "-wal" file.

"databaseList()" method, All files in database folder are returned.
Such as "-wal" file, "-shm" file and so on.

In case of media provider, it uses WAL mode.
If "-wal" file is deleted, side effects appear to SQLITE_IOERR_SHORT_READ and user data is deleted.
Therefore, When deleting a database file, ".db" extension should be checked.
