c-routine for a 16-byte integer array taken verbatim from the
optimized c version reported in
https://en.wikipedia.org/wiki/Fletcher%27s_checksum#Optimizations
except for the fact that the data size is not an argument of the
function but rather the address of its location is passed, as this
is what a fortran call passes as reference.
The type of these variables is also defined as uint32_t
instead of size_t because this is what fortran implicitely does.
Fortran interfaces to a generic subroutine fletcher32_cksum also
defined in UtilXlib/fletcher32_mod.f90

Duplicate module mp_bands.f90 moved from KS_Solvers/XX to UtilXlib/mp_bands_util.f90
Makefiles and makedepend.sh updated
that should take care of the duplicate symbols

clocks can be limited up to a certain depth level (given as optional
argument to init_clocks) so as to reduce the ammount of printed stuff.
printed message shortened , stdout flushed.

removal of old-style fortran to C binding and of configure hacks. The
fortran timing functions are now f_tcpu and f_wall, with obvious meaning

basic operations: error handling, timing clocks, interfaces to basic mpi
calls, find free units...
These routines are moved from Modules and dependencies to other modules
are removed.
MANY files are updated to comply with the move.
