Bug 694570 (2/2) - Stop using libgnome and libgnomeui on Linux. r=acomminos
(Based on original patch by Chris Coulson.) Replace session management through libgnome with direct use of libSM and libICE. This allows xsmp session restore on gtk2 and gtk3 builds. Changes in behaviour: - It now only sends the "session-save" notification when the save style is SmSaveLocal or SmSaveBoth. Saving internal state with a save style of SmSaveGlobal is actually incorrect. This means that Firefox now distinguishes between a normal session exit and a session exit with session saving enabled. - As "quit-application-requested" might pop up a dialog, it only does this if the interact style is not SmInteractStyleNone - "quit-application-requested" is only sent after sending SmcInteractRequest and receiving an interact message. - It defers closing the connection to the session manager until the destructor, i.e after the "web-workers-shutdown" async shutdown phase completes. This means that firefox shouldn't be killed too early and lose data (*). * It still might be killed prematurely if it takes too long to quit and the session manager decides to timeout, but that's another story.
