strlen() returns a size_t type, but nla_put accepts an int only. This
breaks a -Werror build of applications using libnl, so avoid this
warning by explicitly casting the length to an int.

It can easily happen that the generated local netlink port is alrady in
use. In that case bind will fail with ADDRINUSE.
Users of libnl3 could workaround this, by managing the local ports
themselves, but sometimes these users are libraries too and they also
don't know which ports might be used by other components.
This patch changes that nl_socket_alloc() no longer initilizes the local
port id immediately. Instead it will be initialized when the user calls
nl_socket_get_local_port() the first time and thereby shows interest in
the value.
If bind() fails with ADDRINUSE, check if the user ever cared about the
local port, i.e. whether the local port is still unset. If it is still
unset, assume that libnl should choose a suitable port and retry until
an unused port can be found.

same with the filter. So in case user frees it before
us, we could just grab a reference here.

This expands functionality for manipulating conntracks over netlink by
adding other attributes to nfnl_ct_build_message(). Added a command link

libnl used 'inetdevice.h' for the IPV4_DEVCONF_* names, which the kernel
in the meantime moved to public user space API and are now defined in 'ip.h'.
As a first step, rename the file 'inetdevice.h'.

Take 'include/uapi/linux/snmp.h' from current kernel v3.13
(commit d8ec26d7f8287f5788a494f56e8814210f0e64be).
The header file added new values for IPSTATS_MIB_* and ICMP6_MIB_*, but
more importantly, the kernel broke user space API by reordering enum values in
IPSTATS_MIB_*. Add a workaround when parsing IFLA_PROTINFO trying to
be compatible with both older and newer kernels.
Note that this workaround might fail for some specific kernel versions by
assuming the old enum value mapping, although the kernel version already
contains the API change. In this case rtnl_link_get_stat() mixes up
values.

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.
