for Cholesky decomposition. These routines are used to parallelize the solvers
for the generalized eigenvalue problems, namely rdiaghg and cdiaghg (notice that
the inversion of the lower triangular matrix L is still done using a serial
lapack routine). These two routines are now used for Davidson parallelization.
Old algorithm based on the orthogonalization of the correction vectors has been
removed (it was awfully slow). The performance of the new algorithm should be
decent. Beware unexpected side effects. C.S.

checks whether or not it is convenient to use the parallel diagonalizer reporting the result.
The output is still verbose to facilitate the identification of bugs.

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
