It's not necessary anymore because gdk_display_manager_get() always
succeeds and the value is independant of when it was called as it's no
longer backend specific.
Add GInitable interface with a default implementation that always
succeeds. This allows backends to override the GInitable implementation
and add their own checks to determine if the backend can be loaded. If
a backend cannot be loaded, GDK can attempt to load the next available
backend.
Since backends may need to read any relevant options (such as the
display flag) to determine if they can be created successfully, this
patch also removes calls that attempt to create the display manager
before the options have been parsed.

The story is slightly different for applications vs libraries;
make it clear that libraries should continue using the lock so
we don't break applications that haven't been ported to the
'single thread' model yet.
This commit deprecates gdk_threads_init, gdk_threads_enter,
gdk_threads_leave and gdk_threads_set_lock_functions. Using GTK+
from multiple threads does not work at all on Windows, and is
problematic on other platforms as well. We want to move to a world
where all GTK+ calls are made from the main thread.
Use g_main_context_invoke, g_idle_add and related functions if you
need to schedule GTK+ calls from other threads.

GDK_NATIVE_WINDOWS was a way to keep some old apps running that did weird
things in gtk2. We should not have to carry this forwards in gtk 3.x.
We do however keep a g_warning() call reminding people of this fact to
ease debugging when they try to port their applications.

This change does not introduce any functionality change, mostly
cosmtic cleanups, like re-linebreak when introduced annotations messed
up indentation or whitespace errors fixes.
Remove the --sync option and remove the possibility of backend-specific
commandline options altogether. --sync is being replaced by
a GDK_SYNCHRONIZE environment variable.
These functions were trivial g_spawn wrappers in all backends
except for X11, and they can be easily replaced by
g_app_info_create_for_commandline + GdkAppLaunchContext.
Commandline arguments should go away altogether, but this one
goes first, since we then don't need to worry about
_gdk_windowing_substitute_screen_number anymore.
This commit hides the GdkDisplayManager instance and class structs,
adds vfuncs for listing displays, opening displays, and getting and
setting the default display. The X11 backend has a derived
GdkDisplayManagerX11.
The gdk_display_manager_get() function is responsible for deciding on
which of the compiled in backends to use. Currently, it consults the
GDK_BACKEND environment variable and falls back to x11.
gdk_enable_multidevice() has been replaced with gdk_disable_multidevice(),
so applications may call that function if they want to go back at the
previous behavior.
There would be usually little reasons to call that function, unless the
application is doing X calls itself that count on old fashioned core
devices.
gdk_threads_mutex, gdk_threads_lock and gdk_threads_unlock are removed
from public API. gdk_threads_mutex was deprecated already. Instead of
using gdk_threads_lock and _unlock one was presumably supposed to use
the GDK_THREADS_ENTER and _LEAVE macros, which now simply call the
corresponding gdk_threads_enter() and _leave() functions.
Remove he dllimport/dllexport ugliness for GDK for Windows.
There is still a gdk_display variable being exported by the X11
backend.
This commit was created using a script that searched for all docstrings
containing a parameter and the string 'or %NULL'.
Gdk backends and demos excluded as they are not part of a public API
