Since our platform requirement is Windows 7+, we don't need GetProcAddress for gesture APIs. But nsWinGesture still uses GetProcAddress for Win7+ API.

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.
