dalcorso d3b85d760a Small changes, forgotten in previous commits.

giannozz afec752184 End of this set of not-so-fundamental changes. Summary: 
1) no more f_defs.h file to be included in fortran files
2) all CMPLX explicitly defined as CMPLX(...,KIND=dp)
3) blas/lapack names in lowercase (not all of them, actually)
4) documentation accordingly updated (plus unrelated changes to user_guide)

dalcorso 8deedeccf7 Minor cleanup of the phonon code. USE phcom substituted with multiple USE statements 
in many routines.

dalcorso d3b31c3cc3 A tentative to improve the phonon recover. 
Introduced four new input variables:

start_q, last_q  Makes the phonon calculation for a subset of the q points.
                 From start_q to last_q.

start_irr, last_irr Makes the phonon calculation for a subset of the
                 irreducible representations.

Removed the input variable maxirr.

Starting k points now written in the punch file.

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 !!!

cazzato a6ad18850a iswitch flag removed; appropriate flags (as lscf, lmd, lphonon, etc.) should be used 
in particular (modenum.ne.0) stands for iswitch = -4 now: is it OK?
unused show_memory routine also removed
documentation updated

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

C.S.

sbraccia 5f4676dda1 Cleanup: all references to varie replaced by references to control_flags 
(also when varie is indirectly called by pwcom).
Fake module varie has been removed from pwcom.

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
