Firefox:Branch Landing

The plan

Branch landing will be done by copying files in browser and toolkit down from the branch and smart-merging changes elsewhere...
Introduce reland-irsn in Status Whiteboard to mark bugs/patches that need relanding, because changes were overwritten by merge of browser/ and toolkit/?

Points to watch carefully and not just clobber

• toolkit/components/startup
• toolkit/components/Makefile.in
• tree wide changes from 237745 affect browser (browser/app/splash.rc, toolkit/content/globalOverlay.js, etc)
• nsXULAppAPI has changed, so has xre_main. Probably nsBrowserApp.cpp should use the trunk version, not the branch version

Already up to date, no merge necessary

• mozilla/chrome (bsmedberg)
• toolkit/locales has been landed (bsmedberg)
• mozilla/browser/components/help/locale/en-US, mozilla/toolkit/components/help/locale/en-US, mozilla/toolkit/components/help/helpOnHelp/locale/en-US (Jeff and Steffen)

Trunk changes to be reapplied quickly to browser and toolkit since they might cause breakage

• tree widget refactoring and enhancement from bug 221619 (checked in after the 1.7-branch was cut, so it missed aviary, which was cut from 1.7).
  Bonsai query limited to browser and toolkit. The full glory.
• A number of #ifdef MOZ_SUNBIRD checks in toolkit makefiles to be able to build sunbird

Trunk landing needed outside browser and toolkit

• new Tabbed Browsing options: bug 172962, bug 263956 (danm?)
• new Plugin Finder Service: bug 244125 (jst/doronr?)

Branch stability fixes to be reverted on trunk

• Turn on Stylesheet switcher icon (kinda bug 257859)
• Readd bookmark update notification/scheduling (bug 253478)
• Restart-less theme switching (seems to have been left as-is, with dynamic switching enabled now)
• Single Window Mode (enabled by Ben during aviary landing)
• others?
