Commit 3cb28534d3 enables building
of cli always as part of `make check`. As cli previously always
included <dlfcn.h>, this broke tests for building with toolchains
that don't support dynamic library loading.
Add a configure check and disable dlopen() based on whether
<dlfcn.h> is available.

When configuring with --enable-cli=no, we should not build
the libraries related the cli.
This fixes commit 3cb2853 (build: enable building cli during tests)
which enables building of cli during `make check`. However, during
regular build, these libraries should not get build.

- for rtnl_rule_set_l3mdev(), also allow unsetting the l3mdev field.
In practice, kernel only allows for two options: either omit
tb[FRA_L3MDEV] or set it to 1. As such, rtnl_rule_set_l3mdev()
allows for both of these. In principle the setter could get
extended to set other values. Such values are reserved.
- for rtnl_rule_get_l3mdev() also return an error code. I think it
is appropriate to mix value and negative error code, as long as
the range of values cannot overlap with error codes.
Arguably, the outcome is a bit awkward, as the function now is
expected to return -NLE_MISSING_ATTR or 1. So, the best check
is probably
if (rtnl_rule_get_l3mdev(r) > 0) { ... }
The reason for this change is that libnl should expose the netlink
API without coercing uint8 to boolean. That way, future changes
in kernel don't require update to libnl3.

Add support for the l3mdev option in FIB rules. If l3mdev is set
then the lookup is directed to the table associated with the l3mdev
(e.g., VRF) device.
If the l3mev attribute is set the table id is not, so update the table
id attribute to make sure r_table is non-0.
iproute2 shows the rule as:
1000: from all lookup [l3mdev-table]
where [l3mdev-table] infers the dynamic nature of the table id. Keep
that notation for libnl.

Add functions to access the IPv6 specific flags of a link object.
Also the functions for IPv6 link flags translation are now exported, similar
to the non IPv6 specific translation functions.

uClibc doesn't implement strerror_l() and thus libnl starting from
3.2.29 couldn't be compiled with it any longer.
To work-around that problem we'll just do a check on strerror_l()
availability during configuration and if it's not there just fall back
to locale-less strerror().

First release candidate for upcoming libnl 3.3.0 release.
Note that from now on, future libnl3 release will bump the
second version number, instead of the third. So the next
version will be 3.3.0 instead of 3.2.30.
This does not imply a break of API/ABI, it is only a change
of the versioning scheme.

The previous commits reorganized the public headers to drop includes
of linux kernel headers.
Restore the previous situation because otherwise the change might
break compilation for users who rely on certain headers getting dragged
in by libnl3.
It would be desirable not to include kernel headers in our public
libnl3 headers. As a test, remove all those includes, and fix
compilation by explicitly including the kernel headers where needed.
In some cases, that requires forward declaration for kernel
structures, as we use them as part of our own headers.
Realistically, we cannot drop those includes as it probalby breaks
compilation for users that expect to get a certain kernel header
when including a libnl3 header. So, this will not be done and the
includes will be restored in the next commit.
Do this step to show how it would be and to verify that we could
build with such a change. The reason not to do this is backward
compatibility (at compile-time).
For out-of-tree builds, we must ensure that the build directory
for the generated sources exists. We do that by adding a dependency
to the .dirstamp file.
and xfrmnl_sp_set_sec_ctx(). The user already must pass a NUL
terminated string, where the NUL is included in ctx_len.
Just allocate one more by and ensure the buffer is '\0' terminated.
The previous API of xfrmnl_sp_get_sec_ctx() is totally broken,
as it requires all out-arguments to be set. The user can thus
not know how large the ctx_str buffer must be.
Fix the API by allowing all arguments to be optional. Thus,
a user can first query the size only, and then in a second
step query the ctx_str. Previous version are broken.
security policy can be identified with direction, selector and security context
too. Therefore the code to append approptiate data to delete message is added.
Identification of policy are possible with:
1. direction and index
2. direction and selector
Theoretically second one needs a security context, but non existing context is
valid too.
Fixed xfrmnl_sp->sec_ctx length parameters in xfrmnl_sp_set_sec_ctx,
because former use of only one value wasn't right.
Therefore parameter len is unsued and could be removed.
fdb cache is per bridge and hence hashed by:

newer kernels send bridge ifindex in NDA_MASTER.

Also imports a few more NDA_* attributes from upstream
to keep linux/neighbour.h NDA_* attributes in sync with

The cli programs don't have any additional external dependencies.
So, during a `make check`, we should always build them, even if
they were disabled during configure and won't be installed.
