Add hw accelerator module to send PCM data to DSP and get
back the effects processed data.
Expose a wrapper library for AudioFlinger to be able use the new
module to apply the DSP audio effects.

Silence data is getting written from in_read when voice
call is muted with USB Headset connected. This resulting
in muting Rx path too along with Tx path in this
scenario. USB Voice call scenario, PROXY_IN device is
responsible for reading RX data. So not supposed to be
muted.
Fix is to avoid muting if the current use case is AFE_PROXY

When pcm offload is done, override the buffer size
that was calculated and use the value from the system property
Make write call blocking if small buffers are used in offload
Update latency value for pcm offload with small buffer hint based
on period size and period count.

During MP3 (with no gapless meta data) playback in 'repeat one song'
mode observed that from second iteration onwards the progress
bar continues to increase beyond the clip duration.
At the end of second iteration the drain command is not reaching the
driver as the compress_set_gapless_metadata() is not called.
Fix the issue by ensuring that it gets called for every iteration.

-DAP bypass / DAP on will be set from audioflinger when HDMI
passthrough starts and ends.
-Setting it from HAL has state mismatch between app/ effect
library and dap hal.

AudioPolicyManager closeOutput triggers resetting device to speaker
when playback ends. This results in an unexpected error in kernel
driver due incorrect topology being picked. Avoid resetting to speaker
device in hal to fix this issue.

-Add support for HDMI passthrough for DD/DDP contents to HAL and
APM.
-Add mixer control to set volume on volume module on passthrough
COPP. The mixer control takes zero volume for mute and unity
volume for max volume.
-DDP content requires sample rate to be four times native sample
rate. HAL sample rate is changed to four times native rate from
start output stream. During rapid pause/resume offload thread
calls standby when there is no active track and no activity for
over a second. On resume start output steam is called and
sample rate is converted to four times its current value.
This results in session to be started with invalid sampling
rate and playback failures.
-Add HDMI passthrough support for JOC format.
Expose DDP/JOC as pass-through supported format if sink
supports either DD or DDP. This is to allow support for
pass-through convert based on edid data.
-Deep buffer music stream does not switch back to HDMI after
ringtone playback ends. Ringtone, alarm, notification etc are
played on speaker if HDMI pass-through is enabled. The
decision is taken based on stream or strategy. The decision
to change the device from HDMI to speaker is taken based on
the stream type. When a patricular stream ends use the
reference count instead of stream type.
-DAP is not turned on when switching from passthrough stream to
deep buffer stream.DAP bypass call from HAL to DAP HAL expects
integer pointer. Address of a bool variable is passed into the
function. Corrupt value is set on driver instead of turn on/off
causing random failures in DAP on/DAP bypass. Use same data type
and use enumeration to make the function call readable.

The Audio COPP topology is hard coded to NULL topology in kernel
for incall recording stream. Remove the hard coding in kernel and
send default input device's audio calibration from audio hal
so that AUDIO_TX_MONO_COPP topology will be used for incall
recording stream.
This change is needed to be able to fine tune audio calibration
data for incall recording stream.

before compress driver is opened. Return 0(NO_ERROR) in this case
to avoid playback failures.
