If we're doing automatic routing with default routes, but the config has
also specified an explicit fwmark, then use that explicit fwmark, even
if it's conflicting, since the administrator has explicitly opted into
using it. Also, when shutting down the interface, we only now remove the
fancy rules if we're in automatic routing mode with default routes.

Some older broken resolvconfs don't support resolvconf -l, but do have a
file in a standard location, so use it.

Some older broken resolvconf implementations ignore -m, but do have an
interface-order list. It's better to use this list dynamically, in case
it changes, or in case it's not used by the OS's resolvconf
implementation, such as in the case of systemd or openresolv.

This reverts commit e5203543a674453ce1e0cbbcb234d3308762fe65.
As swanky as it is to have a really short file, it's hard to justify and
makes me nervous.

Before, this meant that it simply took the last 15 characters, instead
of erroring out when there's more than 15 chars.

This reverts commit da4ff396cc5d5e0ff21f9ecbc2f951c048c63fff and adds
some optimizations to hacl64.

For now, it's faster:
hacl64: 109782 cycles per call
fiat64: 108984 cycles per call
It's quite possible this commit will be reverted with nice changes from
INRIA, though.

While this has a negative performance impact on x86_64, it has a
positive performance impact on smaller machines, which is where we're
actually using this code. For example, an A53:
Before: fiat32: 228605 cycles per call
After: fiat32: 188307 cycles per call

* 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.
