Xidorn Quan 7705aa3262 Bug 1160014 part 1 - Implement common part of fullscreen transition. r=roc,smaug,dao 
This patch implements the code which is shared by all platforms for
fullscreen transition.

It adds two prefs for the duration of fullscreen transition. They can
also be used to completely suppress the transition.

In addition, this patch uses the newly added prefs to suppress the
transition in all tests which use the DOM fullscreen.
