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.

Revert "Remove smiley support"

This reverts commit c7c68dba4f3440f234f65eef579f9aaa82682f8c.

It seems that the smiley support has been removed by a Google Dev (Tom Taylor)
without any explanations:
    https://android.googlesource.com/platform/packages/apps/Mms/+/c7c68db

This modification gets the smiley back:
 * ASCII Smileys are converted to images in all received/sent messages.
 * A new menu entry (Insert smiley) is available in the menu of a conversation
   view (ComposeMessageActivity).

I also added this support in QuickMessage too (by parsing the message
just before sending it to the TextView).

Mms: Clear notifications and mark messages read in certain situations

I made these changes to CarbonRom (a fork of CM11), and I
heard that people were still having these issues in CM11.
These two commits (merged into one here) fix issues where messages
in the Mms app were not getting marked as read in certain situations, 
and the notification was not getting cleared when tapped.

More details about these bugs can be found in my original commits to
Carbon:
