Until now the configuration available to user for HW offload were:
hw_offload = no
hw_offload = yes
With this commit users will be able to configure auto mode using:
hw_offload = auto

Until now there were 2 hw_offload modes: no/yes
* hw_offload = no : Configure the SA without HW offload.
* hw_offload = yes : Configure the SA with HW offload.
In this case, if the device does not support
offloading, SA creation will fail.
This commit introduces a new mode: hw_offload = auto
----------------------------------------------------
If the device and kernel support HW offload, configure
the SA with HW offload, but do not fail SA creation otherwise.

Reqids for the same traffic selectors are now stable so we don't have to
pass reqids of previously installed CHILD_SAs. Likewise, we don't need
to know the reqid of the newly installed trap policy as we now uninstall
by name.
With IKEv1 we transmit both public DH factors (used to derive the initial
IV) besides the shared secret. So these messages could get significantly
larger than 1024 bytes, depending on the DH group (modp2048 just about
fits into it). The new default of 2048 bytes should be fine up to modp4096
and for larger groups the buffer size may be increased (an error is
logged should this happen).
This can be useful if routing rules (instead of e.g. route metrics) are used
to switch from one to another interface (i.e. from one to another
routing table). Since we currently don't evaluate routing rules when
doing the route lookup this is only useful if the kernel-based route
lookup is used.
Resolvesstrongswan/strongswan#88.
If users want to associate secrets with any identity, let 'em. This is
also possible with vici and might help if e.g. the remote identity is
actually %any as that would match a PSK with local IP and %any better
than one with local and different remote IP.
Fixes#2497.
libstrongswan and kernel-netlink are the only two components which do
not adhere to the naming scheme used for all other tests. If the tests
are run by an external application this imposes problems due to clashing
names.

If enabled, add the RADIUS Class attributes received in Access-Accept messages
to RADIUS accounting messages as suggested by RFC 2865 section 5.25.
Fixes#2451.
It seems that there is a race, at least in 10.13, that lets
if_indextoname() fail for the new TUN device. So we delay the call a bit,
which seems to "fix" the issue. It's strange anyway that the previous
delay was only applied when an iface entry was already found.
The value of DHCP_OPTEND is 255. When it is assigned this result in a
sign change as the positive int constant is cast to a signed char and -1
results. Clang 4.0 complains about this.
If an interface is renamed we already have an entry (based on the
ifindex) allocated but previously only set the usable state once
based on the original name.
Fixes#2403.
When querying SAs the keys will end up in this buffer (the allocated
messages that are returned are already wiped). The kernel also returns
XFRM_MSG_NEWSA as response to XFRM_MSG_ALLOCSPI but we can't distinguish
this here as we only see the response.

This prevented new listeners from receiving notifies if they joined
after another listener disconnected previously, and if they themselves
disconnected their old connection would prevent them again from getting
notifies.
Multiple CHILD_SAs sharing the same traffic selectors (e.g. during
make-before-break reauthentication) also have the same reqid assigned.
If all matching entries are removed we could end up without entry even
though an SA exists that still uses these traffic selectors.
Fixes#2373.
