Two types of USB audio devices are defined:
- USB audio device: the audio device in USB device mode while
the Android device is in USB host mode.
- USB audio accessory: the audio device in USB host mode while
the Android device is in USB device mode.
Renamed intents for analog and digital docks to avoid confusion:
- ACTION_USB_ANLG_HEADSET_PLUG to ACTION_ANALOG_AUDIO_DOCK_PLUG
- ACTION_USB_DGTL_HEADSET_PLUG to ACTION_DIGITAL_AUDIO_DOCK_PLUG
Factorized code in AudioService broadcast receiver.

Adds flag argument to setMasterMute. This allows third parties to edit it
without showing the UI, for example.

audio/ogg has been the official mimetype for ogg vorbis audio for
a while now, so we should support it.

Broadcast mastervolume intents regardless of whether the system changed the
volume. This fixes the bug where the volume LEDs stop getting updates.

Added the infrastructure to support the synchronization of playback and
capture actions on specific events.
The first requirement for this feature is to synchronize the audio capture
start with the full rendering of a given audio content.
The applications can further be extended to other use cases
(synchronized playback start...) by adding new synchronization events and
new synchronous control methods on player or recorders.
Also added a method to query the audio session from a ToneGenerator.

This is part of the multi-project commit to move the filter-framework
from system/media/mca to frameworks/base/media/mca.
Note that the filter-framework will soon be replaced with a refactored
version currently under API review (also to go under frameworks/base).
This move is done now to unblock the PDK efforts.

MediaScanner sets DATE_TAKEN with EXIF's datetime tag value. When this information is not available,
ExifInterface will simply return -1 which is accidentally used by MediaScanner.
Adding a check to avoid it so MediaProvider can calculate the date taken from last modified time instead.

Current method implemented by the visualizer to detect that audioflinger has
stopped providing audio buffers does not work if the application
reads pcm captures too fast.
The fix consist in implementing a method based on real time measurement only.
One drawback is that the new method makes use of system calls that add some
overhead to the process and capture functions.
