* commit '8050a02b0130f0ba2e2ddfc240aa59029ee2ac6d':
DO NOT MERGE: Linux sockets are odd, closing a socket descriptor does not abort pending recv/send calls.
Record and playback objects (resp AudioRecord and AudioTrack)
are created using a channel mask, but this information is lost
in the mixer because only the channel count is known to
AudioFlinger. A channel count can always be derived from a
channel mask.
The change consists in:
- disambiguiting variable names for channel masks and counts
- passing the mask information from the client to AudioFlinger
and the mixer.
- when using the DIRECT ouput, only verifying the format of
the track is compatible with the output's for PCM.

o Application can make informed decision about the available network bandwidth
when cache fetcher pauses.
o Application can also adjust how frequently the bandwidth is estimated within
a range from one second to one minute.

Moved and renamed media/EffectApi.h to hardware/audio_effect.h
Modified the effect library API to expose a library info structure
containing an interface functions table.
Also removed enums for audio channels, audio format and devices
from effect API and use values from system/audio.h instead.
Modified effects factory to support new library interface format and
load libraries and efffects listed in audio_effects.conf file.
The file audio_effects.conf is first loaded from /vendor/etc and
then from /system/etc/audio_effects.conf if not found.
Modified existing effect libraries to implement the new library interface.

o The intended failure happens if stop() call comes immediately after start() call
before any media data from the output of the encoder is received.

AudioService does not need to unconditionally stop virtual calls
when the audio mode is changed from normal. Only stop virtual calls
that have been started from AudioService.

The AudioManager API to control bluetooth SCO did not provide an easy way for
applications to handle SCO connection errors. When a request to activate SCO with
AudioManager.startBluetoothSco() failed, no state change was indicated via
AudioManager.ACTION_SCO_AUDIO_STATE_CHANGED intent. The application had to
implement a timeout to handle connection failures.
The API change consists in defining a new intent AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED
and deprecate AudioManager.ACTION_SCO_AUDIO_STATE_CHANGED. The new intent
will broacast a new state CONNECTING when the SCO connection is initiated.
The application can monitor changes from CONNECTING to either CONNECTED or DISCONNECTED
states to detect connection success or failure.
An extra indicating the previous state is also added to the new intent.
Also improved BluetoothHeadset service management in AudioService. A disconnection
from the service is not considered as a device or SCO link disconnection. Instead, if the
service interface is not present when a request to activate SCO is received, an
attempt is made to reconnect to the service.
