Support genetlink families using simple fixed headers.
Assume fixed header is identical for all ops of the family for now.
Fixed headers are added to the request and reply structs as a _hdr
member, and copied to/from netlink messages appropriately.

Introduce support for attribute type bitfield32.
Note that since the generated code works with struct nla_bitfield32,
the generator adds netlink.h to the list of includes for userspace
headers in case any bitfield32 is present.
Note that this is added only to genetlink-legacy scheme as requested
by Jakub Kicinski.

Add "fixed" part of the user space Netlink Spec-based library.
This will get linked with the protocol implementations to form
a full API.
