Add __va_copy and make it always visible, in spite of the __ISO_C_VISIBLE
setting. Make va_copy be an alias if __ISO_C_VISIBLE >= 1999.
Why? more than a few ports have an autoconf that looks for __va_copy
because it is available on glibc. It is critical that we use it if
at all possible on amd64. It generally isn't a problem for i386 and its
ilk because autoconf driven code tends to fall back to an assignment.
