For the missing JSON debug print a generic JSON print interface is
proposed.
A specific nla_policy is describing (a) the key name of the entry and
(b) the corresponding callback function for printing the value.
If the netlink attribute is not at disposal no entry for that will be
printed.

This patch reffering to following patches:
