Version of bigdft bumped to 1.7_pre24, moved from sci-libs to sci-physics. No longer used as a library by sci-physics/abinit. Usage of LIBDIR/finclude abandoned in favour of /usr/include, as used upstream.
Abinit & friends upgraded to sci-physics/abinit-7.2.2. BigDFT moved from sci-libs to sci-physics, sci-physics/abinit uses sci-libs/bigdft-abi instead. Usage of LIBDIR/finclude abandoned in favour of /usr/include, as mostly used upstream. Old files cleaned up.

Trying to commit a complex change of sci-physics/abinit and its libraries, I took some
time to put everything in pace so I have to pull some updates before puhing my work. Something
I do not fully understand is happening. If it breaks things I will try to clean up, as soon as
I understand the situation.
The dependency of several packages on sci-libs/libxc modified to reflect correctly the recent change in the upgrade of sci-physics/abinit & friends.
Merge branch 'master' of git+ssh://git.overlays.gentoo.org/proj/sci

Looks like I have broken something. Conflicts are reported in sci-libs/libxc.
Trying desperately to recover.
sci-physics/openmx upgraded to 3.7.3 with some openMP and MPI C/F90 juggling, previous sci-physics/openmx-3.6 preserved for the time being.
