kinds of rescaling. The plain 'rescaling' is performed whenever the
difference between the actual and target T exceeds a given value (tolp).
This is the same for all cases: CP and PW, both fixed- and variable-cell
MD. The previous rescalings of PW get different names:
rescale-v, rescale-T, reduce-T (suggestions for better names are welcome).
The usage of 'tolp' in variable-cell MD is changed and aligned to the
definition used in fixed-cell MD and in CP. Documentation corrected and
updated. Note that the 'langevin' thermostat mentioned in the code is
still undocumented and maybe not implemented.

- correct an unquoted string (iosys) in PW/input.f90:483
(this was the cause of tonight compilation failere)
- correct a few incorrect format strings
- make more use of the constants module and thus
provide more consistent units. NOTE, this has some
numerical changes in the outputs, as in some places
rather low precision and inconsistent numbers were
used for unit conversion.
- convert all(?) single precision constants to double
using the attached little perl program.
exceptions: efermi.f90 (as it is supposed to be rewritten
anyways), plotbands.f90 (it uses single precision everywhere,
which may result in saving a significant amount of memory,
so i converted the two double precision constants to single).
Unused routine 'set_fft_grid' removed

DISCLAIMER
There are accuracy issues to be understood better, we may need properly
modifies pseudopotentials in order to avoid (or reduce) errors when
ecutrho is still insufficient to describe all Fourier components of the
augmentation charge.
In this case (that is nearly always) also the usal G-space has errors
(negative charges for molecules and surfaces, for instance) but they are
usually small and we are used to live with them.
Some experience is needed to understand the relevance of the error related
to R-space augmentation charges.
CP has R-space augmentation with small-boxes.
They also produce some different, usually small, errors.
I think (I may be wrong) this is the origin of the fact that sometime PWscf
and CP total energies are not exactly the same.

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.

Whatever files opened in openfil.f90 will be opened in 'nodedir' (wfc, igk, ...)

-the NH velocities also need to be all saved [nhpdim*nhpcl]

The following variant of the DIIS Residual Minimization Method, based
on three steps, has been implemented :
1) At the first "scf" step of the first "ionic" step, the diagonalization
starts with an initialization procedure. Two (or more) sweeps on all
the bands are performed. A sweep consists in two (or more if required)
unconstrained trial steps (steepest descent steps) followed by a
subspace rotation. If convergence is not achieved in this phase a
final trial step is done.
In all the other cases the initialization procedure consists in a
subspace rotation followed by a trial step.
2) Diagonalization based on the DIIS algorithm is performed on the lowest
( nbnd - 2 ) bands. Orthogonalization of the eigenvectors is done at
each step. The possibility of orthogonalizing a given band only to
those inside an energy window is also implemented.
3) The topmost two bands are converged using a standard
conjugate-gradient procedure. This ensures that eventual holes
left by the DIIS algorithm can be identified and filled.
If two holes have been found this procedure is repeated on the
topmost two bands (previously optimized with the DIIS algorithm).

Molecular Dynamics based algorithm partially rewritten:
both standard and damped MD are performed with the velocity Verlet
scheme (with or without constrains).
Renata's subroutines are used only in the framework of variable
cell.
constrain.f90 file is no longer needed: cnstrains are set in the
input file (see CONSTRAINTS CARD) with the same input format used
in FPMD. An arbitrary number of constrains can be set.
In the case of constrained relaxation the damped MD
algorithm is used instead of BFGS.
When restart_mode = "from_scratch" many reastr files are removed
from the scratch directory.
Several other modifications here and there. (C.S.)

order to allow to specify how to fill starting ns occupation
matrices. Useful when the default choice take the wrong
(or not desired) path.

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

This value of ethr is overwritten (with a warning message) in the case of a phonon calculation (lphonon flag added). If diago_thr_init is not specified in the input file it is automatically set in setup.f90 (for example in the case of a nscf calculation ethr = tr2 / nelec).
I hope this policy is appropriate for all kind of calculations.

NEB/ removed from makedeps.sh
plotrho: added possibility to have contour lines of various type
A few undefined variables defined (again)

variable wf_collect added to the control namelist.
This logical variable will be used in pw to
collect wave funcions at the end of a parallel run.

- substitution of USE ... with USE ... ONLY ...
- directories and filenames moved to io_files,
common to all codes
- clean up in control_flags

From now on, all new input variables should be added
to this module, and then copied to the code internal
variables in the input.f90 subroutine
The namelists and cards parsers are in :
Modules/read_namelists.f90 and Modules/read_cards.f90
files input_parameters.f90 read_namelists.f90 read_cards.f90
are shared by all codes, while each code has its own version
of input.f90 ( used to copy input values into internals variables ).
EXAMPLE:
suppose you need to add a new input variable called "pippo"
to the namelist control, then:
1) add pippo to the input_parameters.f90 file containing the
namelist control
INTEGER :: pippo = 0
NAMELIST / control / ....., pippo
remember: always set an initialization value!
2) add pippo to the control_default subroutine
( cantained in module read_namelists.f90 )
subroutine control_default( prog )
...
IF( prog == 'PW' ) pippo = 10
...
end subroutine
this routine set the default value for pippo,
that could vary with the code
3) add pippo to the control_bcast subroutine
( cantained in module read_namelists.f90 )
subroutine control_bcast( )
...
call mp_bcast( pippo )
...
end subroutine
4) add pippo to the control_checkin subroutine
( cantained in module read_namelists.f90 )
subroutine control_checking( prog )
...
IF( pippo < 0 ) &
CALL error(' control_checkin ',' variable pippo less than 0 ', 1 )
...
end subroutine
5) Copy the value of pippo in the code internal variables
( file input.f90 )
subroutine iosys()
use input_parameters, only: ...., pippo
use pwcom, only: ....., myvar
...
call read_namelists( 'PW' )
...
myvar = pippo
...
end subroutine

PRIVATE keyword added to all FPMD source files,
variables that have to be known outside the module
are explicitly declared as PUBLIC
CPV:
now CP uses the same input parser as FPMD

io_base: strings with the name of the data sections added to the
restart file, this will allow R/W of data sections in any order
