kernel-interface: Add a separate "update" flag to add_sa()
...
The current "inbound" flag is used for two purposes: To define the actual
direction of the SA, but also to determine the operation used for SA
installation. If an SPI has been allocated, an update operation is required
instead of an add.
While the inbound flag normally defines the kind of operation required, this
is not necessarily true in all cases. On the HA passive node, we install inbound
SAs without prior SPI allocation.

kernel-interface: Pass full list of traffic selectors to add_sa()
...
While we can handle the first selector only in BEET mode in kernel-netlink,
passing the full list gives the backend more flexibility how to handle this
information.

kernel-interface: Remove reqid parameter from get_spi/get_cpi() methods
...
The reqid is not strictly required, as we set the reqid with the update
call when installing the negotiated SA.
If we don't need a reqid at this stage, we can later allocate the reqid in
the kernel backend once the SA parameters have been fully negotaited. This
allows us to assign the same reqid for the same selectors to avoid conflicts
on backends this is necessary.

kernel-wfp: Install outbound ALE connect rules for IPsec
...
Similar to the inbound rules, the ALE filter processes IP-in-IP packets for
outbound tunnel mode traffic. When using an outbound default-drop policy,
Windows does not allow connection initiation without these explicit rules.

kernel-wfp: Install inbound ALE IP-in-IP filters
...
When processing inbound tunnel mode packets, Windows decrypts packets and
filters them as IP-in-IP packets. We therefore require an ALE filter that
calls the FWPM_CALLOUT_IPSEC_INBOUND_TUNNEL_ALE_ACCEPT callout to allow them
when using a default-drop policy.
Without these rules, any outbound packet created an ALE state that allows
inbound packets as well. Processing inbound packets without any outbound
traffic fails without these rules.

kernel-wfp: Set flag to get UDP encapsulation with tunnel mode working

Having this flag set fixes connections initiated by the Windows host, but
unfortunately does not yet fix incoming connections. Connection state issue?
We still see 0xc00000e2 error events, translating to INTERNAL_ERROR.

Also some MinGW headers define some enum values incorrectly, we overload these
using defines.
