Add missing AH_TEMPLATE entries for autoheader compatibility 

The AC_DEFINE macros for HAVE_LROUND, HAVE_LLROUND, HAVE_NAN,
HAVE_FMIN, HAVE_FMAX, and UINT64_T_AND_ULONG_SAME lack AH_TEMPLATE
declarations, causing autoheader to fail with newer autoconf versions.
Add the corresponding AH_TEMPLATE calls so autoheader can generate
proper config.h.in templates.

Also add the missing #undef entries to the hand-maintained config.h.in
to match.
