This series from Davide converts most of the MPTCP Netlink interface
(plus uAPI bits) to use sources generated by YNL using a YAML spec file.

This new YAML file is useful to validate the API and to generate a good
documentation page.

Patch 1 modifies YNL spec to support "uns-admin-perm" for genetlink
legacy.

Patch 2 adds support for validating exact length of netlink attrs.

Patch 3 converts Netlink structures from small_ops to ops to prepare the
switch to YAML.

Patch 4 adds the Netlink YAML spec for MPTCP.

Patch 5 adds and uses a new header file generated from the new YAML
spec.

Patch 6 renames some handlers to match the ones generated from the YAML
spec.

Patch 7 adds and uses Netlink policies automatically generated from the
YAML spec.

v2 changes:
 - de-uglify YAML spec file, replacing '_' with '-' and avoiding
   unnecessary assignments in enums (Jakub Kicinski)
 - keep validating addr6 with NLA_POLICY_EXACT_LEN() (Jakub Kicinski)
 - Don't leave MPTCP_EVENT_UNSPEC undocumented (Simon Horman)
