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.

Using the same convention in system_init.cpp, you can disable these
services by setting system properties:
system_init.startaudioservice=0
system_init.startmountservice=0

Enabled by setting system property ro.config.headless to 1
This will allow the framework to run without starting activities,
system UI and the keyguard.
Framework can still run services, content providers and broadcast receivers.

Fix a few places where we would unfreeze the screen too early.
Now that we are no longer relying on surface flinger freezing, we
can't depend on it keeping the screen frozen until surfaces get
drawn.

The correct behavior for the light sensor is to immediately report a value
when it is enabled, so this change should not be necessary.

This reverts commit 5dca30affc517879315b3a928c78756cbc9cf689.
...wallpaper first time IRK81.
We were monitoring for file creates when those are not needed, and
receiving the initial file create was causing us to be confused.

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.

The basic problem was that at some points during setup wizard, this would
happen:
1. The app's process is killed.
2. The app's process is restarted, but not to actually resume the
setup wizard activity, just to put it in the stopped state.
When doing this, the saved state is cleared but the app will
never provide a new one.
3. The app's process is killed again. At this point, because the
saved state is cleared, the activity is completely removed.
4. Eventually the entire activity stack becomes empty, and a new
setup wizard activity needs to be created as the home app.
There is a combination of bad stuff going on here.
First, why is the process being killed? At this point the setup
wizard is the home app, so it shouldn't be killed. There were two
reasons why this was happening:
- CryptKeeper still was not completely cleanly going away. To fix
this, I removed the check in the activity manager to not allow
an activity to finish if it is the only activity on the stack and
maybe-kindof looks like the home app. This really wasn't necessary
(we always take care of starting a new home activity if we find the
stack is empty), and outright dangerous with all of these things
purporting to be home but not.
- There was an issue in computing the oom_adj where the home app
would not be marked as "not hidden", and if we had to re-compute
its oom adj in the current sequence would then give it an
adjustment as a background process... and with all the processes
we spin through during boot, it quickly got down to background
#16 and killed.
Second, what is going on with the state? This is easier, the code
in the activity manager to create a new activity but put it in the
stopped state was still clearing the saved state. The saved state
should only be cleared when going in to the resumed state. When
going in to the stopped state, we can just keep holding the same
saved state.

The TouchExplorer was not taking into account the case with incative
pointers while dragging. If one puts a finger down and then perfroms
a dragging gestore the explorer tries to inject UP event for the end
of the gesture upon every of the two dragging pointers going up instead
only for one the first went up.

The DPM seemed to always go through ExternalStorageFormatter to wipe the
device and SD card. For SD cards emulated on a fuse filesystem, this
seems to fail unless the device is wholly encrypted. Bypass
ExternalStorageFormatter in those cases and just wipe as normal.
