{netlink,packet,unix}_diag use attribute type 0 for valid
attributes. The value was reserved and usage was prohibited
by the protocol but we can't undo the breakge.
Make libnl accept attribute type 0 to allow parsing these
attributes.

Set the address flags when creating/updating an address with
rtnl_addr_add/rtnl_addr_build_add_request. Before, the flags
were not passed on.
As of now, the flags except IFA_F_NODAD|IFA_F_HOMEADDRESS are ignored by
the kernel. Still pass them on without filtering.

The application could use the same handler for multiple
nl_cb_type events. This patch stores the nl_cb_type in
the nl_cb struct during the callback. This allows the
application to obtain that information using the new
nl_cb_active_type() function. This way the callback
signature remains as is so existing applications are
not affected.

Newer kernels support conntrack zones, which help to partition the
conntrack table into virtual conntrack tables.
This patch is for adding support for the optional attribute, adds
setters and getters, and adds support for the zone ID in the conntrack
dumper.
An example entry in NL_DUMP_LINE format looks like:
tcp SYN_SENT 10.128.128.99:43354 <-> 10.128.129.20:22 zone 1

Recent kernels support conntrack time stamping, which is a helpful
feature to determine the duration of a flow without building a flow
cache in your user space application, just to keep the 'start' time of
your flow.
Timestamps are recorded with nanosecond resolution once this feature
is enabled.
This patch adds optional support for the CTA_TIMESTAMP, then
modifies the dump routine to write that info in a format similar
to /proc/net/nf_conntrack. This is an example output when using
NL_DUMP_LINE:
udp 10.128.128.28:56836 <-> 10.128.129.255:8612 delta-time 30

Introduced by commit 8026fe2e3a ("link:
Free and realloc af specific data upon rtnl_link_set_family()")
link->l_af_data[link->l_af_ops->ao_family] is freed here but not set to
zero. That leads to double free made by link_free_data->do_foreach_af.
Fix this by setting link->l_af_data[link->l_af_ops->ao_family] to zero
rigth after free.

- Inet diag allows users to gather low-level socket information.
- This library provides a higher-level API for creating inetdiag requests (via
idiagnl_connect and idiagnl_send_simple) and parsing the replies (via
idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache).
- Request and message objects provide APIs for accessing and setting the
various properties of each.
- This library also allows the user to parse the inetdiag response attributes
which contain information about traffic class, TOS, congestion, socket
memory info, and more depending on the kernel version used.
- Includes doxygen documentation.
If a hdrlen was provided that was greather than the actual
message length, a negative attributes length would result.
This was typically happening for RTM_GETLINK requests where
we can get a away with a 4 bytes header on the request side
but the response would use a 16 bytes header.
This resulted in strange -8 bytes leftover debug messages.

Since commit "nl: Return -NLE_AGAIN if non-blocking socket would block",

Change it to consider -NLE_AGAIN as a non-error case as it is expected behavior

Since commit: "cache pickup: Avoid duplicates during cache pickup",
nfnl_ct_alloc_cache no longer properly fills the cache, as it doesn't
define oo_id_attrs so all items are considered duplicates.
Instead of adding a ~0 oo_id_attrs to ct_obj, this changes
nl_object_identical to default to comparing all attributes if
neither oo_id_attrs_get or oo_id_attrs are provided.
