I confirmed the patch doesn't add new failures
in both NET_MPSAFE and non-NET_MPSAFE cases.

HEADS UP: bind 9.10.0-P2 imported

[S.P.Zeidler]

Dear all,

I've just imported bind 9.10.0-P2.
Our previous version in HEAD was 9.10.0-b1, so it's not a gigantic
step exactly, but it gets us a release version.

Also I have enabled installation of two new tools, delv and
dnssec-importkey, which also gets us a new library, libirs.

delv (Domain Entity Lookup & Validation) is the tool to use
if your resolver named has issues with the DNSSEC setup of
a domain and you want to find out why.

libisccfg got a version bump, you may want to remove it from your
destdir before building.

regards,
spz
