Since CLI tools don't reliably print the rules pointing to the handler
kernel module, add a dummy rule in the vicinity that contains just a
comment explaining what's there.

The GLib slice allocator has been obsoleted. Having a mixture of two
allocators can lead to hidden issues on systems that use different
implementations. Take the leap and replace everything with g_new/g_free.

Some compilers seem to think that there is some uninitialised usage
here. Work around this.

These don't actually do anything right now as these function don't do an
early return, but having these in place will make things more future
proof.

NFTNL_EXPR_TG_INFO actually expects the info data to be heap allocated
via malloc(), as it will free() it when the expression is freed via
nftnl_expr_free().

We cannot directly use the rule_scratch area when checking for the
nftables status, as this scratch area is re-initialised for each rule.
Instead add check_matched_flag() to be called after each rule was
parsed, and use it to set a corresponding iterate_scratch flag.

These aren't only used to match "immediate" rules, so rename them
accordingly. Make it more clear what check_matched_queue() does.

If base chain is "none", the admin is responsible for jumping into the
custom chain. Don't remove jumps the admin migth have setup.

Change-Id: I9980acb12fb1abb0883b22aceab2719087768763
When base chain is "none", the admin is required to manage jumping into the
rtpengine chain. The chain can't be deleted if it is still referenced by
another rule, which is common in this configuration.

Telling netlink to create a chain that already exists should technically
be a no-op, BUT it still sets the policy to whatever was given as a side
effect. Make sure we don't change the policy by explicitly checking for
the chain's existence.

In the file implementations follow the rules:
1. Firstly goes the correlated header file, then one empty row.
2. Secondly go system headers, so in angle-brackets, then one empty row.
3. Thirdly, go custom header files, so in double quotes,
then one empty row.
4. If there is "xt_RTPENGINE.h", it's mentioned next, but separately,
then one empty row.
5. If there are pre-processor definitions, they are added.
6. And eventually at least one empty row before the code.
In some situations it's allowed to step aside from the rules,
when inclusions are dependent on each other, so on the sequence,
and also possibly on some inline objects definitions, but if possible
to follow the rules, it's being done.

For the use case with a separate base chain, we want to preempt other
firewall rules by default and insert our immediate jump rule at the
beginning, rather than at the end. Add an option to provide the other
behaviour.

If we're not using a separate base chain, create the target rule with
the UDP filter in place, same as the "immediate" rule in the case with a
base chain.

Setting the target info of an `expr` object doesn't result on the data
being copied by libnftnl (unlike other objects). Use static storage to
fix invalid pointer usage.
