This partially reverts dc4361f.
As we now ensure that items using GResources and GConstructors are always
referenced so that the linker does not optimize them out in a default
Release build, we no longer need to enforce the use of /LTCG, so
/LTCG:incremental will work as well.
The Visual Studio projects used a default setting for link-time code
generation, which is a part of the various linker optimizations that is
available, which is set as /LTCG for Visual Studio 2013 and earlier.
This changed in Visual Studio 2015 to become /LTCG:incremental, which would
cause GResources-generated code to be optimized out during linking, unless
they were referred to directly in the main line code (such as when the
GResource is manually registered), causing programs to crash as a result as
they can't find the needed code/data at run time.
Fix this by explicitly setting /LTCG for all release builds, for Visual
Studio 2010 and later.

...where possible, to make application of patches easier in the future.
The README.txt's and the .sln files are still in Windows/DOS line endings
as they need to be so.
Like the Visual Studio 2008 project files, split up the property sheets
so to ease maintenace, and to prepare to use autotools to fill in the
header entries to "install".
Put some of the items that are frequently repeated in the projects as well,
also to simplify maintenance.
Also, update the autotools files to automate the upgrade of Visual Studio
2010 project as we now have multiple property sheets to copy and process.
Add the PlatformToolset tag to the project configs so that we can use add a
simple script later to the autotools files to copy the projects and change
the value (v100 -> v110) of that tag (and other simple changes) in order
that we can quickly provide and maintain support for Visual Studio 2012
with minimal effort.
Note that at the moment GLib does not yet support the API/SDK requirements
for Windows 8 Modern UI (formerly known as Metro), but this paves the very
initial step.
Added projects to compile the glib-compile-resources and gresource(-tool)
utility programs during the Visual C++ 2010 build process, "install"
the resulting binaries upon successful compilation, and dist the new
.vcxproj and .vcxproj.filters files.
Also updated the property sheet and "install" project to make sure the new
.exe's are indeed "installed" and removed from the "install" project the
dependency on the testglib project as testglib is not an exhausive test on
GLib and people might want to make that project compile different test
programs as they might need.
Just wondering: I have updated the property sheet to create the
gconstructor_as_data.h header for glib-compile-resources, but is it better
to dist that generated header instead as the VS 2008/2010 projects will
depend on a working installation of PERL on Windows?
