* Table=auto (default) selects the current behaviour
* Table=off disables creation of routes altogether
* All other values are passed through to "ip route add"'s table option

We also reduce the optimization level, just in case, but add closure
compiler into the mix.

It's good to have SPDX identifiers in all files as the Linux kernel
developers are working to add these identifiers to all files.
Update all files with the correct SPDX license identifier based on the license
text of the project or based on the license in the file itself. The SPDX
identifier is a legally binding shorthand, which can be used instead of the
full boiler plate text.

This gets us nanoseconds instead of microseconds, which is better, and
we can do this pretty much without freaking out existing userspace,
which doesn't actually make use of the nano/micro seconds field:
zx2c4@thinkpad ~ $ cat a.c
void main()
{
puts(sizeof(struct timeval) == sizeof(struct timespec) ? "success" : "failure");
}
zx2c4@thinkpad ~ $ gcc a.c -m64 && ./a.out
success
zx2c4@thinkpad ~ $ gcc a.c -m32 && ./a.out
success
This doesn't solve y2038 problem, but timespec64 isn't yet a thing in
userspace.

This ensures that on an unclean shutdown, we either see the old content
or the new content, but not empty content.

One types:
for (i = 0 ...
So one should also type:
for_each_obj (obj ...
But the upstream kernel style guidelines are insane, and so we must
instead do:
for_each_obj(obj ...
Ugly, but one must choose his battles wisely.

This lets us do flexible things from wg-quick such as:
PostUp = wg set %i private-key <(pass WireGuard/private-keys/%i)
It also was never a very sensible policy to enforce.

The reference to this is <https://sourceware.org/glibc/wiki/NameResolver>,
which mentions:
"From the perspective of the application that calls getaddrinfo() it
perhaps doesn't matter that much since EAI_FAIL, EAI_NONAME and
EAI_NODATA are all permanent failure codes and the causes are all
permanent failures in the sense that there is no point in retrying
later."
This should cover more early-boot situations.
While we're at it, we clean up the logic a bit so that we don't have a
retry message on the final non-retrying attempt. We also peer into errno
when receiving EAI_SYSTEM, to report to the user what actually happened.
Also, fix the quoting back tick front tick mess.

DaveM suggests we do in fact do this. Others on the same thread weren't
happy about the length of the proposed message, so we also give a bit of
a less dramatic warning.
