removed, a few REAL transformed into DBLE. Note that my previos statement
about REAL is overblown: REAl(C) is perfectly safe if C is a double precision
complex number. All changes should be safe.

Now the input of v_of_rho is the charge density in both real and reciprocal
space (always available within the scf loop); the output is unchanged. This
permits to get rid of one FFT for the calculation of V-Hartree and one for the
calculation of V-XC (\nabla rhr in GGA). Array dimensions removed from the list
of arguments of several routines (they are read from the modules). Unused
variables removed.
2) mix_rho has been modified in order to mix only the fourier components of the
smooth part of the density. The FFTs in the local-TF preconditioning are done
using the coarse mesh (cft3s). The performance of the mixing is almost
unchanged, but the mixing itself is much cheaper. Cleanup of unused variables.
Please, check for posible side effects of these modifications.

The idea is that module funct contains data defining the DFT functional in use
and a number of functions and subroutines to manage them.
Data are PRIVATE and are (shuold be) accessed and set only by function calls.
Basic drivers to compute XC quantities are also included.
It should be the main place where definitions for and calculation of xc
functionals are centralized.
In CPV printout [A.U.] replaced by [HARTREE A.U.] in many places.

1) f_defs.h for definitions to be included in FORTRAN files ONLY
2) c_defs.h for definitions to be included in C files ONLY

correct place (kinds); module "varie" replaced by "control_flags" (not
yet in pwcom, though) - many many files changed.
64-bit cpus (Opteron, maybe Itanium) should now work if __LINUX64 is defined
