rtnl_link: include "netlink.h" before <linux/rtnetlink.h>
<sys/socket.h> has to be included before <linux/netlink.h> because
the latter used to be incomplete in older kernel headers.
As a local wrapper file called netlink.h was introduced earlier
to workaround this and related portability issues, include it before
<linux/rtnetlink.h> that in turn includes <linux/netlink.h>.
This fixes build on systems with older kernel headers.
* rtnl_link.c: Include "netlink.h" before <linux/rtnetlink.h>.
netlink: add a basic rtnetlink parser of link messages
* netlink_route.h: New file.
* rtnl_link.c: Likewise.
* Makefile.am (strace_SOURCES): Add them.
* defs.h (arp_hardware_types, iffflags): New xlat prototypes.
* netlink_route.c: Include "netlink_route.h"
and <linux/rtnetlink.h>.
(netlink_route_decoder_t): New typedef.
(route_decoders): New array.
(decode_netlink_route): Use it.

Move nl_route_types definition from netlink.c to netlink_route.c
The side effect of #include "xlat/nl_route_types.h" is
RTM_* constants properly defined in that header file.
While netlink.c does not use these constants itself,
netlink_route.c is going to need them soon.
* defs.h (nl_route_types): New xlat prototype.
* netlink.c: Move inclusion of "xlat/nl_route_types.h" ...
* netlink_route.c: ... here.
Add terminating comment after each DECL_* macro definition
In an attempt to improve readability.
* defs.h (DECL_IOCTL, DECL_NETLINK, DECL_PRINTNUM, DECL_PRINTNUM_ADDR,
ATTRIBUTE_FORMAT): Add comment that marks end of macro definition.
* netlink_sock_diag (DECL_NETLINK_DIAG_DECODER): Likewise.
* nlattr.h (DECL_NLA): Likewise.
printstr: rename to printstrn, add printstr as a thin wrapper
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.
* defs.h (printstr): Rename to printstrn. All callers updated.
(printstr): New static inline function. All callers updated.
Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
