[v3,00/24] Move nss_dns and parts of libresolv into libc

  I've pushed six already-approved patches, but I didn't want to
resequence the rest.

ns_skip_name has been fixed.  I fuzz-tested it against the old
implementation and found what is arguably a bug in the old
implementation.

I updated the NEWS file with a list of deprecated functions, and a few
more based on a review of the remaining libresolv contents.

I hope I addressed all review comments.

Thanks,
Florian

This again adds new files /usr/lib64/libnss_dns.a and
/usr/lib64/libnss_dns_p.a.

Sorry, I got distracted and forgot to fixup resolv/Makefile, too.
I'm going to send a patch shortly.

Thanks,
