doc: Fix for bad cross-referencing due to use of aliases in Texinfo. * data.cc (FInf): Use NaN form instead of nan for consistency in documentation and with cross-references. * data.cc (FNaN): Use Inf form instead of inf for consistency in documentation and with cross-references. * data.cc (Fnzmax): Re-order Seealso links to find related functions faster. * data.cc (Fmpower): Mention mtimes rather than times in Seealso links. * arith.txi: Add comment about why doc-anchors are needed. Remove anchors to lowercase nan and inf.
