* netlink: initialize mostly unused field
* curve25519: squelch warnings on clang
Code quality improvements.
* man: fix grammar in wg(8) and wg-quick(8)
* man: backlink wg-quick(8) in wg(8)
* man: add a warning to the SaveConfig description
Man page improvements. We hope to rewrite our man pages in mdocml at some
point soon.

* wg-quick: android: split uids into multiple commands
Newer android's ndc implementations have limits on uid size, so we have to
break these into several lists.
* man: document dynamic debug trick for Linux
This comes up occasionally, so it may be useful to mention its
possibility in the man page. At least the Arch Linux and Ubuntu kernels
support dynamic debugging, so this advice will at least help somebody. So that
you don't have to go digging into the commit, this adds this helpful tidbit
to the man page for getting debug logs on Linux:
# modprobe wireguard && echo module wireguard +p > /sys/kernel/debug/dynamic_debug/control
* extract-{handshakes,keys}: rework for upstream kernel
These tools will now use the source code from the running kernel instead of
from the old monolithic repo. Essential for the functioning of Wireshark.
* netlink: remove libmnl requirement
We no longer require libmnl. It turns out that inlining the small subset of
libmnl that we actually use results in a smaller binary than the overhead of
linking to the external library. And we intend to gradually morph this code
into something domain specific as a libwg emerges. Performance has also
increased, thanks to the inliner. On all platforms, wg(8) only needs a normal
libc. Compile time on my system is still less than one second. So all in all
we have: smaller binary, zero dependencies, faster performance.
Packagers should no longer have their wireguard-tools package depend on
libmnl.
* embeddable-wg-library: use newer string_list
* netlink: don't pretend that sysconf isn't a function
Small cleanups.

* Makefile: remove pwd from compile output
* Makefile: add standard 'all' target
* Makefile: evaluate git version lazily
Quality of life improvements for packagers.
* ipc: simplify inflatable buffer and add fuzzer
* fuzz: add generic command argument fuzzer
* fuzz: add set and setconf fuzzers
More fuzzers and a slicker string list implementation. These fuzzers now find
themselves configuring wireguard interfaces from scratch after several million
mutations, which is fun to watch.
* netlink: make sure to clear return value when trying again
Prior, if a dump was interrupted by a concurrent set operation, we'd try
again, but forget to reset an error flag, so we'd keep trying again forever.
Now we do the right thing and succeed when we succeed.
* Makefile: sort inputs to linker so that build is reproducible
Earlier versions of make(1) passed GLOB_NOSORT to glob(3), resulting in the
linker receiving its inputs in a filesystem-dependent order. This screwed up
reproducible builds.

* systemd: update documentation URL
* global: bump copyright
Usual house keeping.
* Makefile: DEBUG_TOOLS -> DEBUG and document
* Makefile: port static analysis check
* dns-hatchet: adjust path for new repo layout
* Makefile: rework automatic version.h mangling
These are some important-ish cleanups for downstream package maintainers that
should make packaging this a lot smoother.
* man: add documentation about removing explicit listen-port
Documentation improvement.
* wg-quick: linux: quote ifname for nft
This should fix issues with weirdly named ifnames and odd versions of nft(8).
* fuzz: find bugs in the config syntax parser
* fuzz: find bugs when parsing uapi input
These are two fuzzers that have been laying around without a repo for a while.
Perhaps somebody with enough compute power will find bugs with them.

As announced on the mailing list, WireGuard will be in Linux 5.6. As a
result, the wg(8) tool, used by OpenWRT in the same manner as ip(8), is
moving to its own wireguard-tools repo. Meanwhile, the out-of-tree
kernel module for kernels 3.10 - 5.5 moved to its own wireguard-linux-
compat repo. Yesterday, releases were cut out of these repos, so this
commit bumps packages to match. Since wg(8) and the compat kernel module
are versioned and released separately, we create a wireguard-tools
Makefile to contain the source for the new tools repo. Later, when
OpenWRT moves permanently to Linux 5.6, we'll drop the original module
package, leaving only the tools. So this commit shuffles the build
definition around a bit but is basically the same idea as before.
