This system-wide change covers the switch of NIS components to the new
client side implementation in order to support IPv6, while detaching
libnsl and nss_nis packages, previously bundled together with glibc.

== Detailed Description ==
glibc bundles the client part of NIS, while this implementation is not
compatible with IPv6, due to the way addresses are represented. NIS
upstream added NIS support for the server and client tools, but for
being able to use this feature, the libnsl and nss_nis needs to be
rebased to the new version. Since NIS has been part of glibc for long
time and it doesn't seem to be necessary (especially given the NIS is
an obsoleted technology for years), it is better to detach those two
packages and deliver them as a separate library.

This change is also related to Sun RPC Removal Change
[https://fedoraproject.org/wiki/Changes/SunRPCRemoval].


== Scope ==
* Proposal owners:
Provide the NIS client implementation as separate packages, and adjust
the glibc packaging to remove the nss_nis subpackage, the NIS header
files, and move libnsl to a new subpackage.

* Other developers:
Packages which used to depend on the libnsl library from glibc will
need to add BuildRequires: libnsl2-devel.

* Release engineering:
#7256: https://pagure.io/releng/issue/7256

* List of deliverables: N/A

* Policies and guidelines:
N/A (not needed for this Change; covered by the existing Packaging Guidelines)

* Trademark approval:
N/A (not needed for this Change)
