Jan Engelhardt 3654654f7a netlink: let nlmsg and nla functions take pointer-to-const args ...

The changed functions do not modify the NL messages and/or attributes
at all. They should use const (similar to strchr), so that callers
which have a const nlmsg/nlattr around can make use of them without
casting.

While at it, constify a data array.
