non-zero exit code if it happens.

This documents the `If-Match: ts-default` header that can be set to only
overwrite the default ACL contents, and also briefly mentions a few of
the new top-level ACL fields.

Instead of iterating over the map to determine the preferred forwarder
on every packet (which could happen concurrently with map mutations),
store it separately in an atomic variable.

Ideally we should strip other invalid characters too, but that would
call for a regexp replacement which increases the number of allocations
and makes `TestVarzHandlerSorting` fail.

Instead of returning a custom error, use ErrGetBaseConfigNotSupported
that seems to be intended for this use case. This fixes DNS resolution
on macOS clients compiled from source.

By default all probes with the same probe interval that have been added
together will run on a synchronized schedule, which results in spiky
resource usage and potential throttling by third-party systems (for
example, OCSP servers used by the TLS probes).
To address this, prober can now run in "spread" mode that will
introduce a random delay before the first run of each probe.

This ensures that each DERP server is probed individually (TLS and STUN)
and also manages per-region mesh probing. Actual probing code has been
copied from cmd/derpprobe.

Instead of treating any interface with a non-ifscope route as a
potential default gateway, now verify that a given route is
actually a default route (0.0.0.0/0 or ::/0).

TLS prober now checks validity period for all server certificates
and verifies OCSP revocation status for the leaf cert.
