Moved audio (alsa actually) utils files to system/core/alsa_utils.
Renamed "audio" utilities to "alsa" to better relect their purpose.
Renamed audio_hw.c -> to audio_hal. c to better reflect its purpose.

In a recording session , the number of bytes read is
not updated when pcm_read() fails. This results in
silence/invalid data being added during a device switch
from USB headset to handset.
Fix is to reset the number of bytes read if pcm_read()
returns an error indicating removal of USB headset.

Do not read the ALSA PCM device configuration when playback
or capture is active.
Do not force ALSA profile update if card and device passed
to out/in_set_parameters() do not change.
Hold the main HAL lock when closing or opening the
ALSA PCM device.

The number of channels can be "forced" using k_force_channels.
If the channel count proposed by AudioFlinger is not permitted
by the device, it is emulated.

Refactoring alsa device attributes to alsa_device_profile.h/.c
Refactoring alsa device state to alsa_device_proxy.h/.c
Refactoring format functions into format.h/.c
Refactoring logging functions into logging.h/.c
Sundry (and extensive) code cleanup
Reworked locking on out_write() and in_read() to allow
simultaneous input/output

Capture configuration was using cached_output_hardware_config
instead of cached_input_hardware_config.
Also enable mono capture by rejecting first attempt to open
an input stream in mono with -EINVAL error: AudioFlinger will reopen in
stereo and do the channel conversion.

Changed audio device API version to 2.0 because of
new enums for audio input and output devices.
Removed implementations of get_supported_devices() in
stub and usb audio modules.

Also don't clear card and device when out_set_parameters is called
to set other parameters.
