nsWindow needs configuration change when rendering on Wayland:
- Always draw to mContainer on Wayland as we can't create custom subsurface for
mShell GdkWindow and listen events on mContainer then.
- GTK_WINDOW_TOPLEVEL can't be positioned on Wayland so create popup windows
as GTK_WINDOW_POPUP to control window position on Wayland.
- Create ePopupTypeMenu GdkWindow as GDK_WINDOW_TYPE_HINT_UTILITY instead of
GDK_WINDOW_TYPE_HINT_POPUP_MENU to create it as subsurface (Bug 1423598).
- Don't do pointer grab on Wayland (see Bug 1377084 for reference).

Wayland compositors do not support GDK_DECOR_BORDER so use CSD decorations exclusively.

To have any effect we need to call gdk_window_set_decorations() on top-level GdkWindow only.
When rendering to mContainer the mGdkWindow belongs to mContainer so we need to get the window
from mShell explicitly.

When drawing to mContainer we still need to honor mShell as top-level window.
It means we have to listen property-notify-event there (as it's window specific),
get _NET_FRAME_EXTENTS here and use at nsWindow::SetWindowClass().

WindowSurfaceWayland is Wayland implementation of WindowSurface class.
One WindowSurfaceWayland object manages drawing of one nsWindow so
those are tied 1:1. It implements base Lock() and Commit() interfaces
from WindowSurface. At Wayland side it represents one wl_surface object.
To perform visualiation of nsWindow, WindowSurfaceWayland contains
one wl_surface and two wl_buffer (by WindowBackBuffer) objects
(as we use double buffering). When nsWindow drawing is finished to
wl_buffer, the wl_buffer is attached to wl_surface and it's sent to
Wayland compositor.

wl_buffer is a main Wayland object with graphics data. wl_buffer basically represent one complete window screen.
When double buffering is involved every window (GdkWindow in our case) utilises two wl_buffers which are cycled.
One is filed with data by application and one is rendered by compositor.
WindowBackBuffer class manages one wl_buffer. It owns wl_buffer object, owns WaylandShmPool (which provides shared memory)
and ties them together.

We allocate shared memory (shm) by mmap(..., MAP_SHARED,...) as an interface between wayland based application
and wayland compositor. We draw our graphics data to the shm and handle to wayland compositor by wl_buffer/wl_surface.
WaylandShmPool acts as a manager of the allocated memory. Allocates it, holds reference to it and releases it.

Refactor ncClipboard::GetData() for better readability, add nsClipboard::SetTransferableData()
to send clipboard data to nsITransferable.
According to Gtk people [1] we can't mix free()/g_free() and malloc()/g_malloc() calls.
Existing nsClipboard code mixes that on some places which can lead to issued on glib built
with specific flags (ENABLE_MEM_PROFILE or ENABLE_MEM_CHECK).

Bug 1421974 introduced new mechanism to hide system titlebar by enabling client-side decorations for main Firefox window. It also causes a regression when the CSD window setup is enabled when system titlebar is hidden by window manager.
This patch fixes that and enables the CSD window setup only for case when it's actualy used.

This patch is based on Karl Tomlinson's (:karlt) demo from Bug 1419456. We use gtk_window_set_titlebar()
to set invisible widget. The widget takes place of GtkHeaderBar which leads Gtk+ to render CSD shadows
and handle window resizing, it does not render any titlebar.
gtk_window_set_titlebar() works on unrealized windows only and mShell is already realized at time
of nsWindow::SetDrawsInTitlebar() call so we need to update recent GtkWidget setup.
In that case we create GdkWindow for mContainer (instead of mShell), create a temporary GtkWindow,
reparent mContainer (which owns mGdkWindow) to it, unrealize mShell and set up the titlebar
for mShell toplevel window.
As a workaround for Gtk+ Bug 791081 we also allocate some valid size for mShell before it's newly realized
with the updated titlebar.

Enables override window manager default with those values:
MOZ_GTK_TITLEBAR_DECORATION=none - Firefox does not mess with decoration
MOZ_GTK_TITLEBAR_DECORATION=client - Firefox tries to disable titlebar rendering and draws shadows by client side decorations.
MOZ_GTK_TITLEBAR_DECORATION=system - Firefox tries to disable titlebar rendering and leave system (window manager) to draw window decorations.

We need apply various titlebar/border configuration which is based on active
window manager and desktop type. The XDG_CURRENT_DESKTOP shell variable contains active
desktop environment which we use at GetCSDSupportLevel().
Unfortunately Ubuntu adds "ubuntu:" prefix at XDG_CURRENT_DESKTOP so we can't do
plain string compare but rather search for DE substring at GetCSDSupportLevel().

The browser.tabs.drawInTitlebar check at nsLookAndFeel is redundant, breaks Thunderbird and dynamic titlebar rendering change. Let's use browser.tabs.drawInTitlebar at browser level and when enabled configure titlebar visibility by moz_gtk* media atoms.

Adding MATE as FLAT as it does not support the shadow borders around the window.
GDK_DECOR_BORDER decoration mode means that the window manager renders borders around the window.
We want the border rendering for CSD_SUPPORT_FULL only which means the border looks like shadows. We don't wand WM to render solid/bold borders around main toplevel window.
