This commit fixes the values passed to darwin_versions. When
transitioning from an autotools build, one should always use:
[lt_current + 1, '@0@.@1@.0'.format(lt_current + 1, lt_revision)]
Autotools didn't add -fvisibility=hidden to the build of libgail-util-3.
Meson does and produces a library that exports no symbols.
Fix this by adding GDK_AVAILABLE_IN_ALL to all functions in the headers.
We need to rename the projects so that when these projects are added
into an all-in-one solution file that will build the GTK+ 2/3 stack,
the names of the projects will not collide with the GTK+-2.x ones,
especially as GTK+-2.x and GTK+-3.x are done to co-exist on the same
system. This is due to the case that the MSVC projects are directly
carried over from the GTK+-2.x ones and was then updated for 3.x.
We still need to update the GUIDs of the projects, so that they won't
conflict with the GTK+-2.x ones.
Use the common automake module from the previous commit in the
Makefile.am's, which means that the Makefile.am's in gdk/ and gtk/ can be
cleaned up as a result. As a side effect, the property sheet that is used
to "install" the build results and headers can now be generated in terms of
the listing of headers to copy during 'make dist', where we can acquire
most of the list of headers to "install", so that we can largely avoid the
situation where the property sheet files are not updated in time for this,
causing missing headers when this build of GTK+ is being used.
Also use the Visual Studio Project file generation for the following
projects:
gtk3-demo
gtk3-demo-application
gtk3-icon-browser
gdk-win32
gdk-broadway
gail-util
So that the maintenace of these project files can be simplified as well.
