Since bluedroid is running outside of system_server, it does not have
the necessary Linux capabilities or filesystem permissions to access
/sys/power/wake_* and /dev/alarm (or any other wake alarm). This change
provides a mechanism by which bluedroid can call back up into Java code
and use the standard Android APIs to get wake locks / wake alarms.

The blank HWC call is being replaced by a setPowerMode() call.
This incorporates all of the blank functionality, but provides added
support for display low power modes, if they are available in hardware.
Currently there are three supported modes:
- HWC_POWER_MODE_OFF : Turn screen off.
- HWC_POWER_MODE_DOZE : Put screen in low power mode.
- HWC_POWER_MODE_NORMAL : Turn screen on, and exit low power mode (if
display was previously in low power mode).
Where applicable, the device driver is expected to retain and restore
the low power mode state of the display during entry and exit from
suspend, respectively.

If an event packet is read containing an unknown sensor handle,
don't pass it on to Sensor Services. Drop it on the floor instead
as it's causing Sensor Services to crash.
Moved read of queue size in sensors_poll_context_t::poll() to post
queue mutex grab for safety.

When channel conversion is enabled and the pipe is opened with less channels
(e.g 1) than the output stream's channels (e.g 2) the input stream's buffer
size was calculated incorrectly which resulted in the input stream buffer size
being larger than the output stream buffer size in terms of time. This
changes the pipe size to take into the account maximum frame size so the
output stream buffer size will be greater or equal to the input stream buffer
size.
In addition, if the pipe is created when the input stream is opened and the
output stream is opened at a different sample rate (e.g input = 8KHz,
output = 48Khz) the pipe will incorrectly rate limit writes to the pipe
resulting in gaps of silence in the data read from the pipe by the input
stream.

The size of hwc_layer_1_t varies depending on whether we're building
for a 32- or 64-bit target. This change splits the padding into two
sections so that we can add more fields without changing the overall
size on either bitness.

Added MHL(Mobile High-definition Link) HAL definition to provide
interface between the hardware driver and the HdmiControlService
which also talks to HDMI-CEC HAL. They are both based on HDMI signal
specification.
MHL version 2.0 and above is supported.

Added audio HAL functions to control audio routing and audio gain.
Audio HALs above version 3.0 must implement these functions.
These functions will be used by the framework instead of
out_set_parameters("routing"=XXX) for device selection on an output
or input stream.
They will also allow direct connection of input devices to output devices
as well as gain control on devices or streams.
The gain or routing capabilities are exposed in audio_polciy.conf file.
