libxc update to 2.2.0 (current stable version)

[p-bro]

libxc-2.2.0 has been released a couple of months ago. Attached patch updates libxc to this version. Build and install works fine, but it has not been tested if the library works.

Hi, thanks for the patch. We're going to need to do a bit of testing with the dependencies though before making this change. I think it is best to upgrade to 2.1.0 first actually, since that has the same interface as 2.0.x, whereas 2.2.0 has a different interface, and the dependencies may not be ready to use it in their current versions. Octopus certainly is not, and I would guess ABINIT isn't either.

Updated to version 2.1.0 in r125410. I had to patch ABINIT to make it able to use even this version.

From the libxc web-page they claim that the interface is the same, only the placement of the fortran library is in a separate library (now linking with -lxcf90 -lxc, instead of -lxc). So I guess it should be fine to allow the compilation against 2.1+ as well?

(identical to 2.1.0, except that the Fortran interfaces are in a separate library)

The dependents could now all accept version 2.2.x, so I have updated to 2.2.3 in r149235.
