Kan-Ru Chen 8ba424eabb Bug 1194751 - Part 6. Use mozilla::widget::ScreenManager in content process. r=mconley
This is the most important part of the patch series. It removes the
PScreenManager protocol and use ScreenManager directly in the content
processes.

Initial and subsequent updates are sent via PContent::RefreshScreens.
struct ScreenDetails are kept to serialize Screen over IPC.

nsIScreenManager::ScreenForNativeWidget is removed because
nsIWidget::GetWidgetScreen can replace it. nsIScreen::GetId is removed
because it's not useful for the more general Screen class.
