dalcorso 98bf9b1e4c Reintroduced the changes to the paw pseudopotential generetion, not merged
in the commit of two days ago.

paulatto 08fedbe2f0 SCF with Projector-Augmented Wave Pseudopotential (PAW) routines added.
This means that a lot of routines have been modified and a few files have
been added. During the year several people have contributed to this code,
mainly Guido Fratesi, Ricardo Mazzarello, Stefano de Gironcoli, Andrea Dal
Corso and me (Lorenzo Paulatto).

A brief report of modified or added files follows, further down you will
find a loger report of modifications that was necessary to merge develop_PAW
branch with the current CVS version.

Current version is not 100% functional, but it doesn't brake anything else and
can be used to generate and test PAW pseudopotential.

Added files that will be removed:
PW/rad_paw_trash.f90
PW/paw_xc.f90

Examples:
examples/PAWexample contains a full test of PAW pseudopotential
for Oxygen. The test consist in these tasks:
 - 2 norm conserving, 2 US and 4 PAW pseudopotentials are
   generated and tested in ld1
 - pw test for an isolated O atom at different cutoffs
 - pw test for an O2 molecule at different O-O distance
please read examples/PAWexample/README for (a few) details.

NOTES:
1. new modifications to atomic_paw (and related) from ADC have been rolled
   back, as they were breaking a lot of things, I will reintroduce them
   later when I am sure that everything works properly.
2. the files PW/paw_xc.f90 and Modules/rad_paw_trash.f90 will be removed in
   the next few weeks.

TODO:
1. use new ld1 XC code as much as possible, and remove legacy XC routines
   from rad_paw_routines
2. full self-consistency with radial energies
3. make new Harris-Foulkes estimate paw-aware
4. provide some kind error estimate
5. FORCES and stress!! (require symmetrization of becsums)
6. cleanup

Versions notation:
OLD=version from 2 years ago used as reference to generate the patches
NEW=CURRENT=current trunk version
PAW=current develop_PAW version

Note: pseudo-potential input and allocation routines changed
      a lot in the last years, this is a diagram:
OLD:PW/readin ~~> PAW:PW/read_pseudo --> disappears
pops out --> PAW:PW/readin ~~> NEW:PW/read_pseudo

added files:
Modules/read_paw.f90    (contains module read_paw_module with subroutines
                         paw_io nullify_pseudo_paw, allocate_pseudo_paw and
                         deallocate_pseudo_paw previously in removed file
                         Modules/readpseudo.f90. Also contains module
                         paw_to_internal with subroutine set_pseudo_paw,
                         previously in upf_to_internal.f90)
PW/paw_xc.f90           (contains OLD=PAW xc and gcxc routines as adapting paw
                         grid code to use new routines was very error prone and
                         quite worthless, as it has to be removed anyway)

the hard ones:
DONE PW/electrons.f90   (adapted code to new syntaxes, a lot of cleanup, removed
                         some PAW junk that can be readded later, removed parts
                         that were applyed twice, or had been removed in trunk,
                         the rhog allocations and usage may need fixes)
DONE PW/mix_rho.f90     (merged tauk and paw additions, a bit of cleanup and smarter
                         variables names)
DONE PW/init_us_1.f90   (qtot redefined with "triangular" index nb,mb-->ijv)

modified for compiling:
Modules/io_files.f90    (depatched)
PW/pwcom.f90            (depatched)
Modules/parameters.f90  (temporary readded cp_lmax = lmaxx+1)
PW/newd.f90             (merge was wrong, redone mostly by hand)
PW/read_ncpp.f90        (depatched)
PW/read_pseudo          (small fixes)
PW/sgam_at_mag.f90      (depatched)
PW/sgama.f90            (depatched)
PW/stres_gradcorr.f90   (depatched)

modified for running:
PW/clean_pw.f90         (added call to deallocate_paw_internals)

Modifications to PAW routines:
1. compute_onecenter_charges and compute_onecenter_charges modified to
   comply with new structure of v_xc (in v_of_rho.f90), requiring new
   g-space densities to be saved and computed --> using old xc routines
   as this code will be removed.
2. qrad size has changed, prad and ptrad had to be changed accordingly.
3. several minor modifications to use new radial grid structure.
4. infomsg arguments changed, very funny bug followed.
5. added new routine deallocate_paw_internals, called by PW/clean_pw.f90
   required to run pp.x with more than one q-point(and good programming
   practice)


    *************************
    *** merge of LD1 code ***
    *************************
2nd try: atomic code replaced with current version, then merge by hand
the files that are used by paw subsystem:
* atomic_paw.f90        (replaced with most recent version from develop_PAW
                         routine us2paw and paw2us taken from newer trunk
                         version, a lot of minor changes.)
* gener_pseudo.f90      (fixes)
* ld1inc.f90            (PAW variables added)
* ld1_readin.f90        (PAW variables added, I am not sure if lpaw should go
                         in input or inputp namelist)
* ld1_writeout.f90      (it was only necessary to add a few lines)
* pseudovloc.f90        (nothing to do)
* run_pseudo.f90        (almost nothing to do)
* set_rho_core.f90      (readded a few lines for lnc2paw)
* write_paw_recon.f90   (nothing to do)
* write_resultsps.f90   (nothing to do: trunk version is more
                         PAW-aware than PAW version)

Main problems were found in subroutines run_pseudo and gen_pseudo,
a little code had to be rewritten to comply with new variable names
and fix with merge.

TODO: fix atomic_paw routines to use minimal allocated arrays insetad
of ndmx sized ones; try to use the pawet as much as possible. Remove
test lines and other garbage. Find a fix for PAW2.

The first week of september Andrea Dal Corso uploaded a few modifications to
the atomic_paw routines. I had to rollback them as the structure of atomic_paw
has changed a lot and reimplementing them is probably easier and definitely
safer than fixing everything. I will do it soon, I swear!
