SerialManager: provides access to serial ports
SerialPort: for reading and writing data to and from serial ports
IO with both array based and direct ByteBuffers is supported.
Accessing serial ports requires android.permission.SERIAL_PORT permission
Each platform must configure list of supported serial ports in the
config_serialPorts resource overlay
(this is needed to prevent apps from accidentally accessing the bluetooth
or other system UARTs).
In addition, the platform uevent.rc file must set the owner to the
/dev/tty* files to "system" so the framework can access the port.

The get_next_write_timestamp method introduced to the audio HAL is optional.
HALs which do not implement it leave it set to NULL. Callers (there is
currently only one in the AudioMixer code) need to be certain to check for NULL
before invoking it.

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.

If an app takes the 5-second ANR timeout before responding to a
drop, but then recovers, we were inappropriately throwing an
exception back at it for having acknowledged the drop after we'd
abandoned the operation out from under it. Now we let such
responses slide without taking any punitive action: the app is
still okay, and the drag/drop operation was cleanly terminated
already anyway.

It is no longer sufficient to check the value of
internal.R.bool.config_showNavigationBar to determine if a
navigation bar (separate from the status bar) is shown on a
device, because the emulator needs to be able to override
this value (now possible by setting qemu.hw.mainkeys to "1"
or "0", for navbar or no navbar, respectively).
This logic is now contained in PhoneWindowManager, and any
clients wishing to know whether the system has a software
nav bar should consult the new hasNavigationBar() method.
