Fix inconsistent back button behavior

By default, a press of the back button will only take effect when the
button is successfully released (the user releases the button while
still focused on it), not when the button is still triggered and pressed
down. To avoid this inconsistent behavior, execute the custom back
logic in the onBackPressed callback instead of onKeyDown.

Android denial of service attack using class 0 SMS messages

Bug 9702645
Bug 11970403 - Change to ClassZeroActivity to singleTask

Cherry pick the change from master.

Making every AlertDialog immediately visible can lead to exhaustion
of graphics-related resources, typically memory, resulting in a
broken bufferqueue/hw renderer, and subsequent system crash.

Make ClassZeroActivity a singleTask activity, and queue incoming
messages if one is already being displayed.
