Alexander V. Chernikov 19e43c163c netlink: add netlink KPI to the kernel by default 
This change does the following:

Base Netlink KPIs (ability to register the family, parse and/or
 write a Netlink message) are always present in the kernel. Specifically,
* Implementation of genetlink family/group registration/removal,
  some base accessors (netlink_generic_kpi.c, 260 LoC) are compiled in
  unconditionally.
* Basic TLV parser functions (netlink_message_parser.c, 507 LoC) are
  compiled in unconditionally.
* Glue functions (netlink<>rtsock), malloc/core sysctl definitions
 (netlink_glue.c, 259 LoC) are compiled in unconditionally.
* The rest of the KPI _functions_ are defined in the netlink_glue.c,
 but their implementation calls a pointer to either the stub function
 or the actual function, depending on whether the module is loaded or not.

This approach allows to have only 1k LoC out of ~3.7k LoC (current
 sys/netlink implementation) in the kernel, which will not grow further.
It also allows for the generic netlink kernel customers to load
 successfully without requiring Netlink module and operate correctly
 once Netlink module is loaded.
