Implement and use solid-csd decoration style to get window offset when solid-csd is used by mShell toplevel window.
Also does not apply margin (resize handler sizes) on popup window as well as Gtk+ do in get_shadow_width().

This patch implements a workaround which alows us to emulate
overlay scrollbars for some Gtk+ themes (Ubuntu/Ambiance),
when an inactive scrollbar thumb is smaller than the active one.
We calculate thumb margin as thumb class margin + difference margin
between active and inactive scrollbars.
Also remove boolean parameter from GetScrollbarMetrics() and implement
GetActiveScrollbarMetrics() to get metrics for active scrollbar.

When system titlebar rendering is disabled and we're in CSD window mode, the window decorations are
rendered by client (application/Gtk) and we don't get _NET_FRAME_EXTENTS property (decoration size) update
for our toplevel window.
So we need to calculate the decoration/shadow size as Gtk+ does, we emulate get_shadow_width()
which is not exported by Gtk+.

Some themes (Adwaita for instance) draws bold dark line at
titlebar bottom. It does not fit well with Firefox tabbar UI so
draw themed titlebar with some extent to make the titlebar
bottom part invisible (it's clipped by cairo).

Some themes (Ambiance for instance) uses first-child/last-child css selectors
to style titlebar buttons. Ubuntu Ambiance theme places titlebar buttons closer
by negative margin applied to them.
We put titlebar buttons to GtkBox as well as Gtk+ does and also keep
the button order here to match first-child/last-child selectors. It also means
we must have maximize/restore as one button to keep the correct order.

GtkHeaderBar has property "spacing" which defines space between buttons at titlebar.
Get this property and apply as margin to titlebar buttons when there's more than one.
Also cache this value for furter use at titlebar metrics cache.

Render titlebar button icons as a part of -moz-window-button-* appearence. It allows us to
theme the icons accordingly. We add a GtkImage widget to header bar buttons as Gtk+ does and
store icon pixel data there and render it at moz_gtk_header_bar_button_paint() as a part
of the buttons. It means that the toolbar buttons are not containers and
moz_gtk_get_widget_border() returns zero border for them.
Also implement GetToolbarButtonMetrics() per button.

Titlebar button on Gtk+ >= 3.20 can have defined its size as min-width and min-height
and can leave CSS styles border/padding empty. To render the button icon at center we need to
calculate button widget border from gap between icon and button.
This is done by GetToolbarButtonMetrics() which also stores final values to
ToolbarButtonGTKMetrics cache.

In the GTK < 3.20 the size of radio and checkbox toggle is determined by indicator
spacing and indicator size. By GTK 3.20+ it is replaced by standard box model
(padding, margin, border). The patch fixes that while keeping the functionality
for older GTK. The values are also cached by similar way as scrollbar metrics
are cached now.
The focus is no longer rendered by GTK but by Mozilla code, so the extra
size for toggles has been removed from GetExtraSizeForWidget and toggles
no longer render focus indicator.

See comments in the header file.
This also clears out mSafeWidgetStates in ThemeChanged since that seems
like a good thing to do, and marks nsNativeThemeGTK as final.

This was used with GTK2, but is now unnecessary as discussed in bug 1278282.
moz_gtk_init() is now called from only one place and so will be called only
once.

Changes in behavior are intended to be minimal, but this adds distinct
metrics for horizontal and vertical scrollbars even with GTK versions < 3.20.
Updates on theme changes will be restored in a subsequent patch.

There is no need to calculate thumb borders because thumb border-box sizes are
determined with GetMinimumWidgetSize, which includes GTK margin, border, and
padding, and the interior border width is irrelevant because thumbs have no
children.
