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.

Hide "Insert smiley" if emoticons are disabled

There's no point in having "insert smiley" option when
graphical emoticons are disabled.
I still hate these emoticons.

Mms: disable SplitActionBar

This makes the UI more consistent with newer Email app look.
