Nicholas Nethercote 0b2b65edc8 Bug 1325503 - Remove Windows {XP, Server 2003, Vista} support from widget/. r=jimm.
I did my best to remove as much stuff as possible in this patch. The starting
point was to remove all the IsVistaOrLater() and IsWin7OrLater() calls, but I
also grepped for various strings and found some other removable stuff that way.
I may have still missed some things.

Notable things done by this patch.

- It removes numerous blocklist entries.

- It removes CanComputeVirtualKeyCodeFromScanCode(), because it's always true
  now.

- It removes ShowXP{Folder,File}Picker(), even though these were available as
  fallbacks on Vista+. The "when platform is built without the longhorn SDK"
  condition in the comment above nsFilePicker::ShowXPFolderPicker() sounds like
  it won't ever happen any more.

- It removes the config.trim_on_minimize preference. This requires adding a
  bool sHaveInitializedPrefs variable; previously the lack of pref
  initialization was indicated by the tri-state sTrimOnMinimize variable having
  the value 2.

Notable things *not* done by this patch.

- ClearThemeRegion() still exists. The comment suggests that it is XP/Vista
  only, but the code suggests otherwise. jimm thinks the comment is wrong.

- The comment in WinWakeLockListener::Callback() suggests that the StartTimer()
  call is no longer needed to block the screen saver. I'm uncertain about this
  and so I think it's best left to a follow-up.
