The long FFTs can now use the multi-threaded FFTW routines. Subroutine decode9.f90 was renamed jt9fano.f90. The JT9 decoder's top-level functions were removed from decoder.f90 and put into a separate subroutine decjt90.f90. Subroutine decoder.f90 is now configured for possible use of OpenMP SECTIONS, with the JT9 and JT65 decoders running concurrently on a multi-core machine. Note, however, that this concurrent processing is not yet fully implemented. Probably calls to timer need to be removed; some variables used in calls to jt65a and decjt9 may need to be declared PRIVATE in decoder; some sections probably need to be declared CRITICAL; probably some SAVE statements in downstream routines have made them not thread-safe; etc., etc. I'm a neophyte at using OpenMP. Comments, suggestions, and/or tests by others will be welcome! git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@4919 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
