npf(9): Drop table lock around copyout.

It is forbidden to hold a spin lock around copyout, and t_lock is a
spin lock.

We need t_lock in order to iterate over the list of entries.
However, during copyout itself, we only need to ensure that the
object we're copying out isn't freed by npf_table_remove or
npf_table_gc.

Fortunately, the only caller of npf_table_list, npf_table_remove, and
npf_table_gc is npfctl_table, and it serializes all of them by the
npf config lock.  So we can safely drop t_lock across copyout.

sys: Use membar_release/acquire around reference drop.

This just goes through my recent reference count membar audit and
changes membar_exit to membar_release and membar_enter to
membar_acquire -- this should make everything cheaper on most CPUs
without hurting correctness, because membar_acquire is generally
cheaper than membar_enter.

sys: Membar audit around reference count releases.

If two threads are using an object that is freed when the reference
count goes to zero, we need to ensure that all memory operations
related to the object happen before freeing the object.

Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one
thread takes responsibility for freeing, but it's not enough to
ensure that the other thread's memory operations happen before the
freeing.

Consider:

	  Thread A			  Thread B
	obj->foo = 42;			obj->baz = 73;
	mumble(&obj->bar);		grumble(&obj->quux);
	/* membar_exit(); */		/* membar_exit(); */
	atomic_dec -- not last		atomic_dec -- last
					/* membar_enter(); */
					KASSERT(invariant(obj->foo,
					    obj->bar));
					free_stuff(obj);

The memory barriers ensure that

	obj->foo = 42;
	mumble(&obj->bar);

in thread A happens before

	KASSERT(invariant(obj->foo, obj->bar));
	free_stuff(obj);

in thread B.  Without them, this ordering is not guaranteed.

So in general it is necessary to do

	membar_exit();
	if (atomic_dec_uint_nv(&obj->refcnt) != 0)
		return;
	membar_enter();

to release a reference, for the `last one out hit the lights' style
of reference counting.  (This is in contrast to the style where one
thread blocks new references and then waits under a lock for existing
ones to drain with a condvar -- no membar needed thanks to mutex(9).)

I searched for atomic_dec to find all these.  Obviously we ought to
have a better abstraction for this because there's so much copypasta.
This is a stop-gap measure to fix actual bugs until we have that.  It
would be nice if an abstraction could gracefully handle the different
styles of reference counting in use -- some years ago I drafted an
API for this, but making it cover everything got a little out of hand
(particularly with struct vnode::v_usecount) and I ended up setting
it aside to work on psref/localcount instead for better scalability.

I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I
only put it on things that look performance-critical on 5sec review.
We should really adopt membar_enter_preatomic/membar_exit_postatomic
or something (except they are applicable only to atomic r/m/w, not to
atomic_load/store_*, making the naming annoying) and get rid of all
the ifdefs.

Major NPF improvements (merge from upstream):
- Switch to the C11-style atomic primitives using atomic_loadstore(9).
- npfkern: introduce the 'state.key.interface' and 'state.key.direction'
  settings.  Users can now choose whether the connection state should be
  strictly per-interface or global at the configuration level.  Keep NAT
  logic to be always per-interface, though.
- npfkern: rewrite the G/C worker logic and make it self-tuning.
- npfkern and libnpf: multiple bug fixes; add param exporting; introduce
  more parameters.  Remove npf_nvlist_{copyin,copyout}() functions and
  refactor npfctl_load_nvlist() with others; add npfctl_run_op() to have
  a single entry point for operations.  Introduce npf_flow_t and clean up
  some code.
- npfctl: lots of fixes for the 'npfctl show' logic; make 'npfctl list'
  more informative; misc usability improvements and more user-friendly
  error messages.
- Amend and improve the manual pages.

npf_worker_sys{init,fini}: initialize/destroy the exit_cv condvar.

NPF improvements:
- Add support for dynamic NETMAP algorithm (stateful net-to-net).
- Add most of the support for the dynamic NAT rules; a little bit more
  userland work is needed to finish this up and enable.
- Replace 'stateful-ends' with more permissive 'stateful-all'.
- Add various tunable parameters and document them, see npf-params(7).
- Reduce the memory usage of the connection state table (conndb).
- Portmap rewrite: use memory more efficiently, handle addresses dynamically.
- Bug fix: add splsoftnet()/splx() around the thmap writers and comment.
- npftest: clean up and simplify; fix some memleaks to make ASAN happy.

Major NPF improvements:
- Convert NPF connection table to thmap.  State lookup is now lock-free.
- Improve connection state G/C: it is now incremental and tunable.
- Add support for dynamic NAT address.  Translation addresses can now be
  selected from a pool of addresses.  There are two selection algorithms,
  "ip-hash" and "round-robin" (see the man page).
- Translation address can be specified as e.g. ifaddrs(wm0) in npf.conf
  to dynamically choose an IP from the interface address(es).
- Add support for the NETMAP algorithm with static NAT for net-to-net
  translation (it is equivalent to iptables NETMAP logic).
- Convert 'ipset' tables to use thmap; the table lookup is now lock-free.
- Misc improvements, bug fixes and more unit tests.
- Bump NPF_VERSION (will also bump libnpf).

NPF: Major rework -- migrate NPF to the libnv library.
- This conversion significantly simplifies the code and moves NPF to
  a binary serialisation format (replacing the XML-like format).
- Fix some memory/reference leaks and possibly use-after-free bugs.
- Bump NPF_VERSION as this change makes libnpf incompatible with the
  previous versions.  Also, different serialisation format means NPF
  connection/config saving and loading is not compatible with the
  previous versions either.

Thanks to christos@ for extra testing.

This patches ditches the ptree(3) library, because it is broken (you
can get missing entries!).  Instead, as a temporary solution, we switch
to a simple linear scan of the hash tables for the longest-prefix-match
(lpm.c lpm.h) algorithm. In fact, with few unique prefixes in the set,
on modern hardware this simple algorithm is pretty fast anyway!

data, fixing up only the RST to the initial SYN.  This makes off-path attacks
more difficult.  For the reference, see "Reflection Scan: an Off-Path Attack
on TCP" by Jan Wrobel.
Implement NPF table listing and preservation of entries on reload.
Bump the version.

NPF checkpoint:
- Add libnpf(3) - a library to control NPF (configuration, ruleset, etc).
- Add NPF support for ftp-proxy(8).
- Add rc.d script for NPF.
- Convert npfctl(8) to use libnpf(3) and thus make it less depressive.
  Note: next clean-up step should be a parser, once dholland@ will finish it.
- Add more documentation.
- Various fixes.

NPF checkpoint:
- Add support for session saving/restoring.
- Add packet logging support (can tcpdump a pseudo-interface).
- Support reload without flushing of sessions; rework some locking.
- Revisit session mangement, replace linking with npf_sentry_t entries.
- Add some counters for statistics, using percpu(9).
- Add IP_DF flag cleansing.
- Fix various bugs; misc clean-up.

NPF checkpoint:
- Add proper TCP state tracking as described in Guido van Rooij paper,
  plus handle TCP Window Scaling option.
- Completely rework npf_cache_t, reduce granularity, simplify code.
- Add npf_addr_t as an abstraction, amend session handling code, as well
  as NAT code et al, to use it.  Now design is prepared for IPv6 support.
- Handle IPv4 fragments i.e. perform packet reassembly.
- Add support for IPv4 ID randomization and minimum TTL enforcement.
- Add support for TCP MSS "clamping".
- Random bits for IPv6.  Various fixes and clean-up.

Fixes/improvements to RB-tree implementation:
1. Fix inverted node order, so that negative value from comparison operator
   would represent lower (left) node, and positive - higher (right) node.
2. Add an argument (i.e. "context"), passed to comparison operators.
3. Change rb_tree_insert_node() to return a node - either inserted one or
   already existing one.
4. Amend the interface to manipulate the actual object, instead of the
   rb_node (in a similar way as Patricia-tree interface does).
5. Update all RB-tree users accordingly.

XXX: Perhaps rename rb.h to rbtree.h, since cleaning-up..

1-3 address the PR/43488 by Jeremy Huddleston.

Passes RB-tree regression tests.

Import NPF - a packet filter.  Some features:

- Designed to be fully MP-safe and highly efficient.

- Tables/IP sets (hash or red-black tree) for high performance lookups.

- Stateful filtering and Network Address Port Translation (NAPT).
  Framework for application level gateways (ALGs).

- Packet inspection engine called n-code processor - inspired by BPF -
  supporting generic RISC-like and specific CISC-like instructions for
  common patterns (e.g. IPv4 address matching).  See npf_ncode(9) manual.

- Convenient userland utility npfctl(8) with npf.conf(8).

NOTE: This is not yet a fully capable alternative to PF or IPFilter.
Further work (support for binat/rdr, return-rst/return-icmp, common ALGs,
state saving/restoring, logging, etc) is in progress.

Thanks a lot to Matt Thomas for various useful comments and code review.
