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.
* The printout of ibrav in xml data file could be wrong if the
initializing routine had to be called multiple times because of the
missed iinitialization of optional pointers to NULL pointer.
* to describe cases with ibrav < 0 the new boolean attribute
use_alternative_axes has been added to the atomic_structure element
in the xml schema, ibrav < 0 corresponds to bravais_index = abs(ibrav)
and use_alternative_axes = .true.
* more pointers to optional arguments are now initialized run time for
the same reason
