gd_nframes64 — report the size of a Dirfile, with largefile support

       This  version of gd_nframes(3) uses a 64-bit offset type (gd_off64_t), where one is available, regardless
       of the size of off_t.  It is only guaranteed to be available if GD_64BIT_API is defined before  including
       getdata.h.

       If  off_t  is a 64-bit type, this function will the same as gd_nframes(3).  Otherwise, gd_nframes(3) will
       be a version of this function which uses a 32-bit off_t.
