Sometimes property service is slow to respond.

Upon boot-up, telephony service will update the system property for
timezone and send out broadcast.The property service won’t handle
the update immediately if the init process was doing something
time-consuming. Meanwhile StatusBar(one broadcast register) may get
the outdated value by reading from system property, because the
update is not handled yet. Then wrong time will be displayed on
status bar.

Signal strength: add more checks to signal strength,

so it doesn't fall under the range of poor signal and automatically
assumes a gsm signal, actually checks if all values are true and not
valid then pass it on to lte or gsm. This fixes cases when gsm signal
is not valid and lte is active. When lte is active and shows a really
weak and gsm signal is not avalible due some broken vendor ril or
just running cdma lte and a few others senario creates this issue.

framework: Allow specifying max wallpaper width

For some devices with very high-res screen (1920x1200), the wallpaper
width suggested by the launcher may be too large for the GPU and so
we need to limit it. (2048 for the above mentioned screen)

We don't need to limit the height since that's the height of the
screen.

Don't recreate keyguard for MCC/MNC changes.

https://github.com/CyanogenMod/android_frameworks_base/commit/8f3abc06fc9d62734f40a2eb1cf69fe5f137ed0b

Fix

...
Keyguard: more consistency with the new lockscreen wallpaper

* In the case when the screen was off and setCustomDrawable()
was being called, and the use wallpaper is null, then we could be
setting the color filter on a null drawable.

* Fix logic when old custom background was null and the new one is also
null (but could be the user one) and the func was being returned, thus not
clearing out the current media album art.

* Move resetting the shouldShowWallpaper() flag to the show() method
so it is not being called every time the screen is turned on.

* Fix user image not showing up on first boot if it exists

SysUI: Don't recreate controllers.

The various controllers, such as mLocationController, get recreated
every time the status bar is recreated due to a theme change.  We
should only need to create these if they are null, otherwise use
the controller as is.  Also, each of these controlers registers
themselves as a broadcast receiver and are never unregistered before
recreating them.
