MTP file transfers happen in two stages. The SendObjectInfo command sends
some information about the file and reserves an ObjectHandle for the new file.
The file transfer is then performed using the SendObject command.
To support this in the media provider, MtpDatabase.beginSendObject receives
the information from SendObjectInfo and creates an row for it in the MTP objects
table for the new file. After the file transfer has completed, then
MtpDatabase.endSendObject is called. In endSendObject, we run the media scanner
on the new file, which will add a row to the images, audio, video
or audio playlist table.
To avoid the media scanner creating a second row for the file in the MTP objects
table, we pass the ObjectHandle created in beginSendObject to the media scanner,
which then passes it to the media provider via the content values when it
performs its insert.

Added JAVA classes to control bass boost, equalizer, reverberation and virtualizer Effects.
Defined the following JAVA classes on top of AudioEffect class to facilitate control
off built-in audio effects with APIs aligned with interfaces defined in OpenSL ES
specification:
- BastBoot.java
- Equalizer.java
- PresetReverb.java
- EnvironmentalReverb.java
- Virtualizer.java
Split reverb API header file in two, one for preset reverb and one for environmental reverb.
Some changes in test reverb to support preset reverb.

Uses a new "MTP objects" table in the media provider to support basic
enumeration of the external storage file system.
Support for accessing audio, video and image metadata in the existing
media provider tables will be added in a later commit.
The C++ MtpDatabase class is now abstract, to support a proxy subclass that
calls through JNI to the Java MtpDatabase class in the media provider.

The visualizer enables application to retrieve part of the currently playing audio for visualization purpose.
It is not an audio recording interface and only returns partial and low quality audio content as a waveform or
a frequency representation (FFT).
Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method.
This commit also includes a change in AudioEffect class:
- the enable()/disable() methods have been replaced bya more standard setEnabled() method.
- some fixes in javadoc

Problem:
When the bluetooth device is removed, the AudioService clears all active SCO connections
and unlinks from the client application's binder interface death.
The problem is that the unlinking is done even if no more connections are active for a given client,
which throws a runtime exception that is not catched causing the system server to crash.
The fix consists in calling unlinkToDeath() in ScoClient.clearCount() only if the number of
active SCO connections for this client is not 0. The NoSuchElementException exception is also
catched when calling unlinkToDeath()

When the media scanner scanned a single file, the modified
date (DATE_MODIFIED) was not correctly set in the content
provider. It was set as milliseconds but should have been
set as seconds. This caused downloaded media items to display
wrongly in the camera album, since the date was wrong.

are supported.
This is enough to support a proof of concept sample program that navigates

Also removed obsolete ptptest host test program.
