Fix sscanf/wcstod parsing of NaNs.

The parsefloat routines -- which let us pass NaNs and infinities on to
strto(f|d|ld) -- come from NetBSD.

Also fix LP64's strtold to return a NaN, and fix all the architectures
to return quiet NaNs.

Also fix wcstof/wcstod/wcstold to use parsefloat so they support hex
floats.

Lots of new tests.
