- acdb and csd client modules are linked into HAL, UCM
at compile time.
- Remove the compile time dependency by loading the modules at
runtime.

This patch avoids abnormal operation in AudioStreamOutALSA::write().
When BT device is turned On/Off, if routing device is 0, then pcm open
will be failed.
- A variable "mDevices" is set to "0" when device is switched to BT A2DP
from speaker during playing music.
- If variable "mDevices" is "0", when PCM data is writing to buffer
in A2DP stream, then a routing device is set "no device".
- And when device is switched to ALSA stream, and PCM open will be failed.
This causes media crash as killing ALSA.

- Currently pcm stream is closed to flush buffers while switching
between speaker+headset combo device and headset device.
- Fix this problem by removing unnecessary pcm stream close.

- Add deep buffer output in config file
- Configure deep buffer output if flag
AUDIO_OUTPUT_FLAG_DEEP_BUFFER is set,
otherwise configure low latency output.
- Add support for low latency recording
- Enable low latency recording path with
system property
- For 2 buffers and 2048 bytes, reduce
PLAYBACK_LOW_LATENCY to 21.5 ms

Sometimes media server is killed by alsa_ucm during device is booting.
A alsa_ucm gets a index of "use case device" from get_use_case_index()
function.
But, get_use_case_index() function can be returned a wrong value
(dev_index = -22 used index of dev_list[] array) at booting time.
This patch avoids latent media server crash causing abnormal value
as using index of dev_list[] array.

Removed implementations of obsolete function get_supported_devices()
Audio HAL wrapper provides conversion between new and old device enums.
It exposes a rev 2.0 audio device API to the audio framework and allow
legacy implementation to use old device enums.
TODO: make sure that Qualcomm proprietary device IDs are defined properly.

Update implementation of AudioPolicyInterface to use the
audio_devices_t type of system/audio.h instead of the
device enum in AudioSystem.
Note that the affected file is currently disabled in the makefile.

Revert back to original libhardware_legacy audio hal headers from AOSP.
This makes corresponding code changes to disable features to match
audio hal implementation with standard libhardware_legacy audio hal.
