Dumps the widget path into a string representation. It tries to match the CSS
style as closely as possible (Note that there might be paths that cannot be
represented in CSS).
The main use of this code is for debugging purposes, so that you can
g_print() the path or dump it in a gdb session.
gtk_entry_set_placeholder_text() makes the entry display the given text
when it is empty and unfocused. Based on previous patch by Alberto
Garcia.

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.

Now that a single shared object can contain multiple backends we also
need to provide a simple way for third party code to verify that the
copy of GDK they are linking to supports their backend.
The simplest way to verify is an m4 macro, GTK_CHECK_BACKEND(), shipped
with the gtk+ m4 macros.
The usage is pretty basic:
GTK_CHECK_BACKEND([x11], [gtk_has_x11=yes], [gtk_has_x11=no])
AM_CONDITIONAL(BUILD_X11_CODE, test "x$gtk_has_x11" = "xno")

At the same time, change the library sonames for -3.0 to just -3.
This is necessary since the 2.99 releases installed libraries like
libgtk-3.0.so.0.9903.0, and we want to prevent the library version
number from jumping back. So 3.0 will have libgtk-3.so.0.0.0.
I think it's confusing for a lot the developers out there who
may not even be aware of GTK+ 3 coming, if suddenly GTK+ 3 becomes
the "stable" version of "gtk" on library.gnome.org. It may
not even be feasible for them to port to GTK+3 if it's not
shipped in the operating systems they're targeting (for example,
RHEL 6).
Since practically speaking, we expect people to consume GTK+ 2 for
several years at least, redirect these people to the right pages.
(I didn't attempt to explain the differences between the libraries
here, but hopefully the major version difference is enough of a hint)
As a side effect, this makes the generated HTML look better; previously
it looked rather crappy, since the "for GTK &version;" was totally
offset and in a different group from the documentation title.
Also added documentation section for this. Since the GtkRecentFilter
documentation was still living in sgml, as a side-effect I migrated these
docs to the gtkrecentfilter.[ch] sources.
