@o Provide Autoconf check (AC_CHECK_VA_COPY) for va_copy(d,s) macro
  and fallback implementations and now that we can be sure that
  va_copy() exists for us, use it in var_formatv() and ts.c instead
  of the direct assignments (which are not sufficiently portable).

o Remove "#undef socklen_t" from sa.h because the socklen_t
  fallback is a "typedef" since a longer time.
