06099b8 allowedips: fix comment style
ce04251 contrib: embedded-wg-library: add ability to add and del interfaces
7403191 queueing: skb_reset: mark as xnet

Changes:

* queueing: skb_reset: mark as xnet

This allows cgroups to classify packets.

* contrib: embedded-wg-library: add ability to add and del interfaces
* contrib: embedded-wg-library: add key generation functions

The embeddable library gains a few extra tricks, for people implementing
plugins for various network managers.

* crypto: read only after init
* allowedips: fix comment style
* messages: MESSAGE_TOTAL is unused
* global: in gnu code, use un-underscored asm
* noise: fix function prototype

Small cleanups.

* compat: workaround netlink refcount bug

An upstream refcounting bug meant that in certain situations it became
impossible to unload the module. So, we work around it in the compat code. The
problem has been fixed in 4.16.

* contrib: keygen-html: rewrite in pure javascript
* Revert "contrib: keygen-html: rewrite in pure javascript"

We nearly moved away from emscripten'ing the fiat32 code, but the resultant
floating point javascript was just too terrifying.

* Kconfig: require DST_CACHE explicitly

Required for certain frankenkernels.

* compat: use correct -include path

Fixes certain out-of-tree build systems.

* noise: align static_identity keys

Gives us better alignment of private keys.

* wg-quick: if resolvconf/interface-order exists, use it
* wg-quick: if resolvconf/run/iface exists, use it

Better compatibility with Debian's resolvconf.

* contrib: add extract-handshakes kprobe example

Small utility for extracting ephemeral key data from the kernel's memory.
