This builds on bug 1428676 and introduces StyleAppearance, which replaces the
NS_THEME_* constants.
Really sorry for the size of the patch.
There's a non-trivial change in the gtk theme, which I submitted separately as
bug 1478385.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

The fix for bug 1373079 neglected the detail of OpenThemeData
that it can return null if no match is found for the specified
class name. The set of matching class data sections varies with
the default and the classic theme, and the classic theme doesn't
have matches for a few of the values that we try to get. This
causes us to pass a null theme to subsequent functions, which of
course breaks the layout.

See commit (1) for more detail about the bug.
This patch caches the expensive parts of GetMinimumWidgetSize,
which are when we call GetDC and ReleaseDC. The exits before this
cached section don't have their results cached partly because
they don't seem to show up in profiles, and partly because we
don't necessarily have a theme part at that point, which means
we would need to have a more complicated caching scheme directly
involving the aWidgetType.

Both GetWidgetBorder and GetMinimumWidgetSize are showing up
in some profiles (see bug for more details.) This is the first
patch in a series of patches which cache the results of these
functions.
Because aWidgetType can map to multiple theme parts, in order to
cover as much as possible with our cache we decided to cache
based off of the theme class and the theme part, which are derived
from the aWidgetType and misc. other state. (Assumption: the
widget border and minimum widget size should not changed based on
the theme "state" (the value that accompanies the "part".))
The total cache size for these, if we use plain arrays, is 18KB.
We could reduce this by some amount by using a sparse dynamically
sized cache or by just using aWidgetType and discarding the
overloaded values, which are few. I don't have a great intuition
for how much we care about saving a few KB, or how much time this
could cause us to lose on L1 and L2 cache misses. Accordingly it
might be more optimal to go with something else, and I am open to
criticism/suggestions.

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.
