This allows all the existing modules to have source level
compatibility until they are fixed to use the new field names.
Since the binary compatibility has not been altered, we do not
need to force all the implementors to rev their version numbers.
This change should be reverted when all the clients have been updated.

The previous names and documentation were not clear as to how the
version fields should be used. As a result, they were often either
unused or used improperly.
It became clear that there were two version fields necessary. One
to version the implementing module and the other to version the
hw_module_t interface itself.
This change renames version_major and version_minor members of
hw_module_t to module_api_version and hal_api_version. It also
provides in-depth descriptions for all the fields and clarifies
the purpose of the version field in hw_device_t structure.

This adds unit tests for implementors of the keymaster API. It can be
compiled and run as a stand-alone executable.

Switch from unspecified encoding for import of keys to PKCS#8 (Java
standard encoding).
Add function for obtaining the public key from a keypair.
Add fields for RSA key generation that indicate modulus size and desired
public exponent.
Add in placeholder fields for possible digest and padding types for
signatures. Currently the only thing supported is "none" and "none"
respectively.

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.

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.

of device independently.
Added functions at the audio policy interface to set and get stream volume
for a particular device.

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.
