    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 in tungsten 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 TungstenTime 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 TungstenTime 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.
    + more progress has been made in eliminating the word "tungsten" from the code.

    Things left to do include
    + Finish getting rid of tungsten from the time service.
    + Move the time service into the framework; AudioFlinger's new timed mode
      depends on it and the service cannot continue to live in vendor tungsten.

    Fix an issue with inconsistent volume reporting.

    Changed masterVolume() to return the same value as the last call
    to setMasterVolume when the HW layer is implementing master
    volume control.  The masterVolume/setMasterVolume API seems to be
    an idea which was abandonded a long time ago; as of today the
    system only ever sets it to 1.0 at startup and then never changes
    it.  Until we can figure out how the concept of external
    amplifier gain control fits into the Android audio framework,
    Tungsten is exposing this API via a hack-tastic invoke back door
    in the TungstenRXPlayer and needs the getter/setter results to be
    consistent.
