These functions are old and therefore do not have the support_ prefix
yet.  The support_check_nss function is kind of separate from the rest,
so I used a different naming pattern.  The new file is called
support/support_check_nss.c to match the function name.

I can rename all the functions if you'd prefer that.

Thanks,
