dalcorso 69c1fd137a Phonon in the noncollinear and spin-orbit case. Routines with small changes.

giannozz 19aaac89fa More miscellanous cleanup from Axel: 
- disable locales via use of LC_ALL=C in all shell scripts
   (which will hopefully make sorted lists more consistent
    between people running with different locales).
 - remove redundant files from PW, NMR_new, VdW, VIB;
   rename subroutines if their functionality is noI
   unchanged from the original source it was taken from.
 - corresponding updates to Makefiles and dependencies.
 - whitespace cleanups (eleminate remaining tabs).
 - a few more float->DBLE

giannozz f533b052d5 dbl => DP (defined as previously dbl was) 
syntax for declarations: real(DP), without "kind="

giannozz bf4bfe222f General cleanup of intrinsic functions: 
conversion to real    => DBLE
(including real part of a complex number)
conversion to complex => CMPLX
complex conjugate     => CONJG
imaginary part        => AIMAG

All functions are uppercase.
CMPLX is preprocessed by f_defs.h and performs an explicit cast:
#define CMPLX(a,b)  cmplx(a,b,kind=DP)
This implies that 1) f_defs.h must be included whenever a CMPLX is present,
2) CMPLX should stay in a single line, 3) DP must be defined.

All occurrences of real, float, dreal, dfloat, dconjg, dimag, dcmplx
removed - please do not reintroduce any of them.
Tested only with ifc7 and g95 - beware unintended side effects

Maybe not the best solution (explicit casts everywhere would be better)
but it can be easily changed with a script if the need arises.
The following code might be used to test for possible trouble:

program test_intrinsic

  implicit none
  integer, parameter :: dp = selected_real_kind(14,200)
  real (kind=dp) :: a = 0.123456789012345_dp
  real (kind=dp) :: b = 0.987654321098765_dp
  complex (kind=dp) :: c = ( 0.123456789012345_dp, 0.987654321098765_dp)

  print *, '      A = ', a
  print *, ' DBLE(A)= ', DBLE(a)
  print *, '      C = ', c
  print *, 'CONJG(C)= ', CONJG(c)
  print *, 'DBLE(c),AIMAG(C)  = ', DBLE(c), AIMAG(c)
  print *, 'CMPLX(A,B,kind=dp)= ', CMPLX( a, b, kind=dp)

end program test_intrinsic

Note that CMPLX and REAL without a cast yield single precision numbers on
ifc7 and g95 !!!

sbraccia 0caeadbd7b Machine-dependent definitions are now contained in two different files (both in /include): 
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

degironc 1e8641955f PH: cleanup of cgsolve_all in order to reduce memory use. 
zstar, epsilon and dynamical matrices written with
    8 digits only (it should not make any significant difference
    and it should be easier to spot differences in dynmat files
    if 0.123456789E-10 is treated as zero)
    symmetrization is applied already to drho (not anymore to dvscf)
                                              (SdG)

giannozz 2da5c01765 becp = <beta|psi> allocated only when needed (except in phonon where it is 
still allocated at the beginning) - misc cleanup

giannozz 0b1a5c9fd8 Extensive module cleanup: DP moved from wrong place (parameters) to the 
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
