Updates and upgrades of filter:
- add minor corrections (r1591 of trunk) in filtreg_mod.F90: some arrays were oversized and the computation of the indexes from which the filter is applied could go wrong in extreme cases.
- adapt filtreg_p.F (r1597 of trunk) so that BLAS routine DGEMM is only used if 'BLAS' preprocessing flag is set.
- update FFT filter routines to match current 'trunk' versions (mostly cosmetic changes, exept for the implementation of use of FFTW in mod_fft_fftw.F90).
- update "arch-PW6_VARGAS.fcm" to enable use of FFTW
NB: implemented FFTs assume working precision to be double precision ; trying to use them when working precision is single precision will clearly end in tragedy.
