and the calculation of U and V from the DFT+U+V ground state.
Also changed tests for DFT+U to start from the DFT+U ground states
and check forces and stress.
Other small corrections.
2. Extension of the XSpectra code to DFT+U+V
3. Hubbard forces and stress: now the (ortho-)atomic orbitals
are read from file (and not recomputed as before)
4. Added examples for the DFT+U+V case in PW and HP
5. Various other small improvements and optimizations
In this commit, the entire Quantum Espresso environment is updated so
that "make all" succeeds and produces functional codes. The resulting
codes were tested with the test-suite and all related tests passed. In
addition, I did some more extensive testing with van der Waals systems,
using the option "verbosity = 'high'" so that the non-local corr. energy
is written out explicitly; in all cases, results were identical to
qe-6.4.1 (also tested in parallel).
Overall, I updated 21 Fortran source files, mostly related to the
handling of the kernel file name(s). Modules/xc_rVV10.f90 saw more
substantial changes and now also computes the kernel on the fly. The
two routines PW/src/generate_rVV10_kernel_table.f90 and
PW/src/generate_vdW_kernel_table.f90 are now removed.
In addition, I updated the developer manual and the PW user guide. I
edited two Makefiles and ran "make depend", resulting in 6 changed
make.depend files. I updated 5 scripts and one README file, mostly
related to examples.
Finally, some of the reference files in the test suite and in some
examples had a rather old format and a "diff" after running those cases
shows unnecessarily many differences. I thus created new reference data
for the vdW cases in the test suite (running "make create-reference-pw")
and I updated the PHonon/examples/example16 and
PW/examples/vdwDF_example references (23 files updated, 11 files
deleted, and 6 files added; the file and directory structure of the
delta-scf calculations needed some more substantial updating). I also
updated PP/examples/ACF_example/reference_vdw-df-cx/atoms.out.
At this point I will do some final testing and cleaning-up of the code.
The next commit fill be the final commit.
1. rewritten the core part of the ESM to improve readability and efficiency
of the code (esm.f90).
2. introduce a new function (exp_erfc(x,y) = exp(x) * erfc(y)) to avoid
getting “NaN” in particular case.
4. two dimensional (xy plane) average charge density and electrostatic
potentials are printed out to ‘prefix.esm1’ instead of stdout
3. make ESM calculation compatible with the NEB (neb.x).
4. introduce the constant bias potential (constant-mu)
(PRL 109, 266101 (2012)) feature to both pw.x and neb.x.
5. write ESM information in the XML file (One can use post-processing program
such as pp.x).
6. including various example calculations.

Functions exc_t, vxc_t moved out of module funct to the only package where
they are used (atomic). They should be replaced by xc, xc_spin sooner or
later.

"pwscf" or "cp" are removed when the scratch directory is cleaned. May still
need some tweaking in some cases, though, because not all files start with
the value of "prefix" variable
