Further cleanup should make this routine unnecessary.

for a bug, before I realized that there were two copies of "gamma_only",
I wasted two more hours to iuse a single value of "gamma_only" (the one
oin control_flags).

is now possible to run the PH code for just one k point out of the
full dispersion grid (specified by nq1, nq2, nq3). This way there is
no need to run PW with 'phonon' first for a non-Gamma k point, and
perhaps, there are some other positive (or negative?) effects that I
am not aware of.

Apparently the reason is insufficient stack size, but it may not be sufficient
to use command "limits" o "ulimit", because the stack size seems to be reset
either by queueing systems or by the code itself. A C routine that removes
stack limits has been added and is called at the beginning of the run.

This variable is .true. when xq is gamma and only the gamma point is used
for k point sampling.
The symmetrization used in phcg.x has been imported in ph.x in the case
lgamma_gamma=.true..

states. This bug (introduced at the end of May 2005) was responsible for
somehow wrong results in the case of calculations with many k-points.
Cleanup of diagonalization thresholds: wg_set variable removed and btype array
is now set in sum_band.
Added a logical input variable (diago_full_acc) to decide if the empty states
(defined as states with occupation < 1%) have to be converged at full accuracy
or not. Defaul is .FALSE. (I am not sure this is the best choice, comments
appreciated).

So far it only works for non-metals and the output is specific for
molecules (it prints polarizability, not the dielectric constants).

dispersions to prevent a stupid error when initializing non-scf
calculations at finite k (the problem arises only with metals).
I don't know if this may cause trouble in other cases, though.

(he claims it is more tested); documentation updated (sort of)
- routines find_free_unit, delete_if_present, moved from 'parser'
to 'io_files' (it is a more natural place)
- routines int_to_char moved from 'parser' to flib/ (it is quite
unrelated with the rest of the module)
- routine trimcheck moved from flib/ to 'io_files' (more natural place)

all files open by seqopn.f90 and diropn.f90 in the TMP_DIR have the
general form "prefix"."extension" where extension is the only part of
the filename passed as an argument. This should avoid conflicts between
different jobs running at the same time and sharing the same TMP_DIR
(provided they have different prefixes ...)
All examples (from 1 to 26) give the same output as before on my pc.
Please let me know if you notice unexpected behaviours.
stefano
PS: example26 apparently does nothing (even giving the command run_example 7)..
As it uses cp.x which does not use seqopn/diropn routines this behaviour
cannot be due to the present changes.

- iotk_scan in iotk_module had a mixed up 'intent' statement.
- sun ultra fire 3 compiler warnings
- cleanup in filename length (brought to 256)
- cleanup in include files

is now within ph.x possible.
New input variables:
lnscf: if .true. the nscf and phonon run are done in one single run
ldisp: if .true. calculation of dyn. matrices for dispersion
nq1, nq2, nq3: q-point mesh

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
