npf(4): Use atomic_store_release and atomic_load_consume for config. ...or atomic_load_relaxed, when the config is locked. (Not necessary to use atomic_* at all in NetBSD, but in C11 it will be cheaper to say atomic_load_relaxed explicitly so an _Atomic-qualified object doesn't cause the load to be surrounded by unnecessary membars.) No need for store-before-load ordering here, so no need to membar_sync.

From David H. Gutteridge. Adjust some internal NPF APIs: * npfkern: use the npfk_ prefix. * NPF portmap: amend the API so it could be used elsewhere. * Make npf_connkey_t public. npf.7: add xref to npf-params.7 (Adding directly here since this particular file isn't included in rmind@'s upstream GitHub repo at present.)
Adjust some internal NPF APIs: * npfkern: use the npfk_ prefix. * NPF portmap: amend the API so it could be used elsewhere. * Make npf_connkey_t public.
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.

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.

Rebase to HEAD as of a few days ago.
NPF: finish up the rework of npfctl_save() mechanism.
Rebase.
NPF: rework of the connection saving and restoring: - Add support for saving a snapshot of the current connections together with a full configuration. Support a reverse load operation. Eliminate the old 'sess-save' and 'sess-load' in favour of the new mechanism. - Share code between load and reload operations: the latter performs load from npf.conf without affecting the connections. - Simplify and fix races with connection loading. - Bump NPF_VERSION.
- npf_nat_freepolicy: handle a race condition when a new connection might be associated with a NAT policy which is going away and npfctl reload would wait for its natural expiration (potentially long time). - Remove npf_ruleset_natreload() by merging into npf_ruleset_reload(). - npf_ruleset_reload: eliminate a small time period when a valid NAT policy might be inactive during the reload operation.

Add npf_tableset_syncdict() to sync the table IDs in the proplib dictionary, as they can change on reload now. Also, fix table name checking in npfctl.
NPF: add support for table naming and remove NPF_TABLE_SLOTS (there is just an arbitrary sanity limit of NPF_MAX_TABLES currently set to 128). Few misc fixes. Bump NPF_VERSION.
NPF: add support for specifying the interfaces before they are attached. If an interface is or gets detached, all associated rules and connections will be deactivated (it might be useful to have an option to invalidate the associated connections). Once the interface is reattached they will become active. Bump NPF_VERSION.
