rtnl_route_build_msg() should allow the user to set the route scope
explicitly to RT_SCOPE_NOWHERE.
This is useful for IPv4 routes, because when deleting a route,
the kernel requires the scope to match, unless the scope is set to
RT_SCOPE_NOWHERE. Thus by setting the scope to RT_SCOPE_NOWHERE,
the user can delete a route, even without knowing its scope.
rtnl_route_build_msg() should only try to guess the scope, if it was
not explicitly specified.

If the duration was without subsecond part, the function always returned
'0msec', instead of giving the time in days, hours, minutes or seconds.
Regression introduced by commit b3fb89f445.

According to documentation, nl_rtgen_request() returns 0 on success,
but before it returned the number of bytes sent.

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.

`make distcheck` builds outside the source directory using
`../configure --srcdir=..`. This was broken because libnl.sym was
expected in the $(top_srcdir) instead of $(top_builddir).

{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.

-Wall is a compiler flag, and thus should be in CFLAGS,
not CPPFLAGS. Similarly, -l belongs into LDADD/LIBADD because of
ordering constraints.
