libfmt: add missing copyright notice to nan64.c
nan64.c was part of change #1 in this repository and did not have a notice at that point (September 2003). An earlier copy of libfmt, dated January 14-15, 2003, makes it clear that nan64.c was extracted from fltfmt.c and strtod.c, so use the same notice they use.
PowerPC Linux support from ericvh.
Mainly adding va_copy/va_end. Also fix bug in sprint wrapping around top of memory.
