sci-physics/openm updated to 3.7.6, corrected linking with fortran code using gcc.

Package-Manager: portage-2.2.1
sci-physics/abinit updated to 7.4.2, the new way of testing adopted. Use of atompaw, bigdft, libxc, and wannier90 made optional, driven by USE flags (atompaw, bigdft, libxc, wannier). USE flag levmar for the new optional Levenberg-Marquardt least-squares algorithm support added. Ebuild cleaned up a bit.

Package-Manager: portage-2.2.1
sci-libs/bigdft removed. Superseded by sci-physics/bigdft and sci-libs/bigdft-abi
sci-libs/wannier90-1.2-r2.ebuild modified from -r1 to avoid sandbox violation when generating TeX fonts.

Package-Manager: portage-2.2.1
sci-libs/bigdft-abi-1.0.4-r2.ebuild modified from -r1 to avoid sandbox violation when generating TeX fonts. Metadata file added, solution to other repoman complaints postponed.
The metadata of sci-physics/abinit augmented by the description of the etsf_io USE flag.

Merge branch 'master' of git+ssh://git.overlays.gentoo.org/proj/sci
Commits of sci-libs/bigdft-abi-1.0.4-r2 messed up, trying to clean up my mess.
There is apparently something wrong happenning with my commits. Trying to go on and get somewhere.
sci-physics/abinit-7.4.2 finally made to actually build and install (tests have to be configured for their Makefile to be where it is looked for during the installation). Testing scripts, written for Python 2, made to run in an environment with Python 3 selected as the main interpreter.
