Including linux/if.h in netlink/route/link.h causes issues
in cases where libnl is used in conjuntion with other third
party libraries that include net/if.h. Seems to be a long
checkered history of symbol collisions between these two
files. As it turns out, including linux/if.h from within
netlink/route/link.h is actually unecessary. I resurrected
a forgotten path from this thread:
http://lists.infradead.org/pipermail/libnl/2012-April/000525.html
By removing the include as the patch suggests we can get
around the nuissance of the symbol collisions.

When we add an action to a filter, its lifetime becomes
same with the filter. So in case user frees it before
us, we could just grab a reference here.

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.
