Tobias Brunner 46c338a78f kernel-interface: Change reqid if seq. nos. are supported and narrowing occurred
With the sequence numbers we don't have to maintain the reqid to delete
the temporary state.

One exception is with labels.  There we currently only install trap
policies with the generic label.  SAs created from those don't have
policies installed, so we have to reuse the reqid of the trap even if
narrowing occurs.

And as before, we reuse the reqid without checking traffic selectors if
sequence numbers are not supported.

Note that if a CHILD_SA is manually initiated (i.e. has no sequence
number assigned) right before an acquire is triggered, there are several
possible outcomes depending on whether narrowing occurs.  If there is no
narrowing, the same reqid is assigned and the kernel will remove the
temporary SA when the SA is installed (no seq => reqid match).
Afterwards, the queued duplicate CHILD_SA is destroyed and the acquire
state in the trap manager gets removed.  If there is narrowing, a new
reqid is allocated, so the installation of the SA will not remove the
temporary state.  However, due to the narrowing, the duplicate check
fails and when the duplicate is installed (with sequence number), the
temporary state is deleted (as is the state in the trap manager).

Tobias Brunner 02180ae2ff kernel-interface: Remove unnecessary parameters for release_reqid()
These are not included in the initial lookup anymore. Also simplified
the implementation as we always add the same entry to the two hash
tables.

Tobias Brunner b9131c34d3 kernel-interface: Add feature to indicate if query_sa() returns last use time
Currently supported by libipsec and PF_KEY on macOS (FreeBSD, like Linux,
reports the time the SA was first used in sadb_lifetime_usetime - it also
triggers rekeyings based on that, which Linux doesn't, it also triggers
them if an SA is never used).

Thomas Egerer 4ea61dcbfe kernel-interface: Make first reqid configurable
This can be helpful to reserve low reqids for manual configuration.

Noel KuntzeandTobias Brunner 09f4bccfea kernel-netlink: Implement passthrough type routes and use them on Linux
Enables us to ignore any future kernel features for routes unless
we actually need to consider them for the source IP routes.

Also enables us to actually really skip IPsec processing for those networks
(because even the routes don't touch those packets). It's more what
users expect.
