Fix divisions by zero on boot.

Change I976ffae3a56d411b00026f86b16efa9743a23293 introduced a problem
where depending on the rotation settings the WM override display
configuration would be filled with invalid values.
Fix that by correctly checking that the display is ready prior to
setting the override configuration.

Fix pie controls being disabled by launcher gestures.

Some launchers have gestures for expanding/collapsing the status bar
from swipe gestures which call the respective StatusBarService methods
even if the status bar isn't visible due to expanded desktop. Because of
that, the status bar code internally thinks the expansion is carried out
(even if invisible), thus disabling the bottom pie controls in the
process.
Fix that by making PhoneStatusBar aware of it being hidden by expanded
desktop and ignoring the expand call in that case.

Remove opaque check in GLRenderer when preparing dirty region.

Since preserved swap is enabled, we need to clear the color buffer
when the scissor rect is prepared for a new process. This prevents
garbage to be present from the previous process in the color buffer.

Enable scissor when preparing dirty rect that is opaque

Now enabling scissor before setting it in the opaque case, previously was not doing so.

Merge Navigation Bar and Pie Controls button config (1/2)

Based on the commit series for pie controls, this commit
makes the Navigation Bar and Pie Controls share
the same button layout. However, there is no button layout
editor for pie controls, which makes the navigation bar
the leading entity when it comes to button layouts.

This commit introduces:
* A common notion of navigation buttons.
  (class NavigationButtons)
* Some setting constants changes.
* Removal of the pie search key, since it is no longer needed.
* Sophisticated key event injection.
* Virtual key sound effect

Improving pie control's user interaction

User feedback showed that it is sometimes difficult to interact
with pie controls. This commit adds some tweaks to how pie
controls react on user touch events.

This changes:
* Pie trigger on LEFT and RIGHT are now more forgiving in the
  initial phase of a swipe. (This should reduce problems when
  trying to activate the pie with a thumb.)
* Pie items are now more sloppy when it comes to focus.

Patch Set #2:
* Removed sloppy focus.

Fix DateUtils.formatElapsedTime.

Fix potential deadlock between LockScreen and WindowManagerService

If LockScreen is enhanced using SurfaceView/GLSurfaceView,
deadlock problem between LockScreen and WindowManagerService
can occur because of IWindow.resized() callback.
And it must lead to watchdog and reset.

IWindow.resized() callback is one-way function so calling resized()
callback of a remote IWindow object is never blocked.
However, calling resized() callback of a local IWindow object
(LockScreen is running on the same system_server process)
is always blocked until resized() callback returns.
Because resized() callback of SurfaceView/GLSurfaceView can lead to
WindowManagerService.relayoutWindow() call, deadlock can occur
between relayoutWindow() and performLayoutAndPlaceSurfacesLockedInner().
(Both functions need locking mWindowMap)

So this patch simulate one-way call when calling resized() callback
of a local IWindow object.

use Calendar in DateUtils format method

The DatePickerDialog is using DateUtils to format the dialog's title
and the DateUtils class does not work with dates outside to the
specified range.
For example, if user selects 2038-03-07, DatePickerDialog shows
1902-01-30 on Title.
The reason for the DateUtils class not being able to format dates
outside the range of 1902 and 2036 is because internally it is using
the Time class which does not support such dates.
To fix it, use Calendar class in DataUilts format method.

Steps to reproduce:
1. Settings -> Date & time
2. uncheck Automatic date & time
3. Set Date
4. choose any date before 1902 or after 2037
5. update wrong date on Title

AudioService: Don't adjust volume when vol-downing to vibrate or silent

Pressing vol-down to vibrate or silent would (previously) still adjust the
stream volume, setting the last audible volume to 0, which is not allowed
for voice-capable devices.  Thus, the last audible volume would reset to
default on reboot if on vibrate/silent or the lowest volume setting.

By not adjusting volume when vol-downing to vibrate or silent on
voice-capable devices, the last audible volume is always preserved across
reboot.
Remove unnecessary updateSurfaceScreenOn call.

This change stops updateSurfaceScreenOn() from being called one time
right after another. It's called at the end of stayAwake(boolean awake),
which is called right before updateSurfaceScreenOn() in release().

Adapt navigation bar's long press behaviour for pie controls

This commit brings the navigation bar long press behaviour to
pie controls.

Two things will be considered for long press:
* Long press on HOME will open Google Now.
* Long press on BACK will kill an application if enabled within
  the debug options.

Patch Set #2:
* Jacob's colours

Patch Set #3:
* More blueish colours
* Using a longer time out for long press
  (getLongPressTimeout() * 2)
* Moved killForegroundAppication() around

Patch Set #5:
* Shortened long press time out a bit
* Adjust time for info shade dynamically
