TLS 1.3 uses HMAC-based Extract-and-Expand Key Derivation Function (HKDF)
as defined in RFC 5869 to compute traffic secrets.

The key material, in particular the nonce/IV, is derived differently and
the IV is also generated in a different way. Additionally, the actual
content type is encrypted and there may be optional padding to mask the
actual size of the encrypted data.
This allows us to use it without having to initialize libcharon, which
was required for the logging (we probably could have included debug.h
instead of daemon.h to workaround that but this seems more correct).
This is similar to the eap-aka-3gpp2 plugin. K (optionally concatenated
with OPc) may be configured as binary EAP secret in ipsec.secrets or
swanctl.conf.
Based on a patch by Thomas Strangert.
Fixes#2326.
On failure the SA is deleted and reestablished as configured. The task
is activated after the REAUTH_COMPLETE task so a make-before-break reauth
is completed before the new SA might get torn down.
Since we don't use the kernel-netlink plugin anymore and the headers
in the NDK are reasonably recent, we don't need this anymore (at least
when building the app).
Fixes#1172.
If additional tasks get queued before/while rekeying an IKE_SA, these get
migrated to the new IKE_SA. We previously did not trigger initiation of these
tasks, though, leaving the task unexecuted until a new task gets queued.
To quickly check out IKE_SAs and find associated CHILD_SAs, the
child_sa_manager stores relations between CHILD_SAs and IKE_SAs. It provides
CHILD_SA specific IKE_SA checkout functions wrapping the ike_sa_manager.
This is mainly because the other parts of the existing android plugin
can not be built in the NDK (access to keystore and system properties are
not part of the stable NDK libraries).
Because all packages are now marked as optional executables that are to
be installed on the final system have to be added to PRODUCT_PACKAGES in
build/target/product/core.mk. Dependencies (such as libraries) are
installed automatically.
