Bash does not propagate error values, which is a bummer, but process
substitutions are a useful feature. Introduce a new idiom to deal with
this: either "; wait $!" after the line to propagate the error, or "||
true" to indicate explicitly that we don't care about the error.

We also make these constant time, even though we're never distinguishing
between bits of a secret using them. From that perspective, though, this
is markedly better than the locale-specific table lookups in glibc, even
though base64 characters span two cache lines and valid private keys
must hit both.

Users can now run `systemctl reload wg-quick@wgnet0`, as described in
the wg-quick(8) man page. Note that this won't adjust Address=, DNS=, or
the various other non-wg(8) fields.

If DNS= has an IP in it, treat it as a DNS server. If DNS= has a non-IP
in it, treat it as a DNS search domain.

Prior we only supported a blacklist, but actually a whitelist is an
easier algorithm because that's internally how netd considers it, so we
don't need to find range spans. This commit adds an IncludedApplications
key.

These are generic helper functions we don't want to move into the actual
implementations, so that it's easy to keep parity with the kernel code.

It turns out that the binary actually gets smaller if we simply inline
the very small parts of libmnl that we need. Since we wind up needing
the mnlg bits anyway, there's little benefit in linking to libmnl.

Now that WireGuard has been upstreamed and the repos split, we have to
look elsewhere for these headers.

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 advise will at least help somebody.

We previously included $(pwd) in the compile output pretty printer,
because it matched our parent out-of-tree module build. Since we're no
longer coupled to the module, we can return to a prettier scheme of just
using the object name.
