Finish renaming mapper function finite to isfinite. * mappers.cc (Fisfinite): Call isfinite() rather than finite(). * ov-base.cc (get_umap_name): Change C string representation of enum umap_isfinite to "isfinite". * ov-base.h (enum unary_mapper_t): Change umap_finite to umap_isfinite. * ov-complex.cc, ov-cx-mat.cc, ov-cx-sparse.cc, ov-float.cc, ov-flt-complex.cc, ov-flt-cx-mat.cc, ov-flt-re-mat.cc, ov-intx.h, ov-re-mat.cc, ov-re-sparse.cc, ov-scalar.cc: Replace instances of umap_finite to umap_isfinite in macros. * ov.h: Replace instance of umap_finite to umap_isfinite in macro. Adjust code comments for better readability.
