Fill out a missing entry in the audio HAL function table.
The entry for get_initial_master_volume was missing from the non-legacy audio
HAL and needs to be filled out. Also fix up the order of the comments
describing the get_initial_master_volume method.

Change the signature of set_local_slew.
Changed the definition of the slew function in the local time HAL to take an
int16 instead of an int32 and to use the full range of the int instead of
attempting to imply any particular PPM range.

Remove "primary" from the local_time HAL.
Interface instances are a pattern which should only be used by audio. Remove
its use from the local_time HAL.

Refactor the local/common clock services.
This change is one of a set of 5 changes made to different repositories. Look
for this comment in all of them.
Refactor the local/common clock services to match android best
practice. Notable changes include
+ The kernel no longer knows anything about common time. Common time has been
moved completely up into user land. This has an impact on the accuracy of the
timesync debugging code, and the netfilter assisted approach to network based
timesync is going to have to be modified.
+ The timesync driver used by A@H is now just local time driver.
+ The kernel no longer needs access to the linear transform math code, and it
has been removed.
+ A new HAL has been introduced to expose the concept of local time to the
system.
+ A non-slewable stub implementation of the local time HAL based on
CLOCK_MONOTONIC has been added.
+ The old library has been eliminated. Its functionality has been
distributed among the common time binder service, the local time hal and the
linear transform utility code.
+ All clients of the old library have been changed to be clients of
the binder service, the hal and the utility code.
+ The reset_tt utilities have been removed, they no longer have a purpose in the
system.

At higher levels, SurfaceTextures include timestamp information in
their buffers. For accurate timestamps, they need to be set by the
driver code. This change adds the needed method into
preview_stream_ops.
Timestamp behavior is documented in SurfaceTexture.java, and
system/core/include/window.h, as well as here.

Improve volume management by keeping track of volume for each type
of device independently.
Added functions at the audio policy interface to set and get stream volume
for a particular device.
Change-Id: Ic8899e82e48193cb65b3673e9d20383efed943b5
Added API to query and configure effects supporting auxiliary channels.
An auxiliary channel contains an additional audio signal helping in the
processing of the main channel. An example is a dual mic noise suppressor
were the main channel contains the signal from the main mic and the aux channel
containss the signal from the sub mic.

Renamed audio effect library interface command for audio format
configuration from EFFECT_CMD_CONFIGURE to EFFECT_CMD_SET_CONFIG.
This makes the naming more consistent with other exixsting commands
and allow adding new a command to get the configuration (EFFECT_CMD_GET_CONFIG).
Same change for reverse channel configuration renamed from
EFFECT_CMD_CONFIGURE_REVERSE to EFFECT_CMD_SET_CONFIG_REVERSE.

This change adds a new Gralloc usage bit to indicate that a buffer will
be passed to the HW video encoder.

First implementation of a NFC HAL. This implementation doesn't
offer a generic NFC device HAL (yet), but offers typed interfaces
for different NFC controllers. Currently only the PN544 is supported.

the current API / Documentation would not allow to set the
rate of "non continuous" sensors.
Most sensors HAL implementation already support changing the rate
(technically they're not compliant with the doc), so it's easier
to change the doc (and also allows more control).

This header is required by our GLES emulation guest code to be able
to access the emulator services provided through the /dev/qemu_pipe
special device.
Change-Id: Ia9782256048d7340237f3e1d18d7452dd815e561
Added a method on audio policy interface to register
audio effect CPU usage on enable and unregister on disable
instead of when the effect is created or destroyed.

This change adds a new Gralloc usage bit to indicate that the Gralloc
buffer being allocated will be passed to the HWComposer HAL module.
