Remove opaque check in preparing dirty region

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

SystemUI: show date on 2 lines in status bar
This allows showing of the full day of the week, and removes
the blank space above the date (which always felt strange to
me when clicking it to access the calendar).

It also fixes a spacing issue on smaller screen devices that
causes the quick settings button to be partially chopped off
when the AM/PM clock settings are enabled.

Fixed an accidentally dot showed in some languages (for ex. US english)

FW: Fix Menu Overflow Disable Option

The three button Menu Overflow would display no matter what setting was seleted within ROMControl, this commit makes a slight change to correctly return a result that reflects the users selection through ROMControl.

I had to enable then disable the option for it to function correctly (no reboot required), screenshot is below showing the absence of the overflow menu:

EthernetDataTracker: Set network available on connected

This change fixes state mismatch found in the bugs below,
and makes the code look consistent with disconnect().

In startMonitoring(), reconnect() is called before mNMService.registerObserver().
Then dhcpThread.run() could finish without getting interfaceLinkStateChanged() callback.
In such a case, mNetworkInfo has connected but not-available state - which is contradictory.
