Move all X specific code into the x11/ directory.
Aside from shuffling things around, did the following:
* gdk/gdkprivate.h gdk/gdk.h gdk/x11/gdkmain-x11.h: Add
gdk_arg_context_* - a simple argument parsing system
in the style of popt.
* gdk/gdkdrawable.[ch] gdk/gdkprivate.h gdk/gdkwindow.[ch]
gdk/x11/gdkprivate-x11.h:
Remove X specific stuff from GdkDrawable and GdkWindowPrivate -
add ->klass and ->klass_data fields. The klass_data
field points to an auxilliary structure that is
windowing system dependent.
* gdk/gdkfont.c: Make most of the measurement functions
simply wrappers around gdk_text_extents().
* gdk/gdkfont.c gdk/gdkprivate.h gdk/x11/gdkfont-x11.c: Add a
_gdk_font_strlen() function that hides the weird
behavior in gtk+-1.[02] where a string is interpreted
differently for 8-bit and 16-bit fonts.
* gdk/gdkevents.c: Add a new function gdk_event_button_generate()
to store common code for synthesizing double/triple
press events.
* gdk/gdkgc.[ch]: Virtualize in the same way as gdkdrawable.h.
Make all the function that modify an existing GC
simply wrappers around gdk_gc_set_values().
* gdk/gdkcc.[ch]: Moved into x11/ directory in preparation
for throwing out later.
* gdk/gdkfont.c gdk/gdkimage.c gdk/gdkcolor.c: Change GdkFontPrivate,
GdkImagePrivate and GdkColormapPrivate to have a
windowing system dependent part (GdkFontPrivateX etc.)
that "derives" from the system-independent part.
* configure.in gdk/x11/Makefile.in gdk/x11/gdkinput*.c:
Got rid of the included-source-files for XInput in
favor of automake conditionals. (Which didn't exist
when XInput support was originally added.)
* gdk/gdkrgb.c: Remove the visual id from the debugging
statements since that is X11 specific; print out
type/depth info instead.
