It is complicated to cache tc actions, they are different
from tc qdisc's and filters by design. So, it is simple
if we just don't cache them.
This patch only removes the tc action cache allocation API.
We still need to bypass the libnl cache layer from scratch,
but that would not break ABI any more, therefore we can do
it later.

Usually the peer of a veth device is moved to a new netns
after creation, so add a pid parameter to rtnl_link_veth_add().

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

- 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.
The batched verdict implicitely ACKs all queue packet IDs up to the
one send back, which reduces the number of verdict messages send
to the kernel.

This provides support for the new bridging attributes provided
in IFLA_PROTINFO while maintaining backwards compatibility
with older kernels.
A set of new API functions are exported to access the bridging
information. rtnl_link_bridge_has_ext_info() can be used to
check whether a bridge object has been constructed based on
the newly available attributes or the old message format.
