Nothing it declares is used by CoreDNS and it does not appear to be used
by any third-party packages (according to godoc.org).

miekg/dns recently became more aggressive in setting TC; anything that's
chopped of a response results in TC. Amend the tests. Disputable if
these TC checks still add something.

* unit test

* fix domain length validation

* code optimization

* remove unit test

Ditch our truncation code and use the upstream one in miekg/dns.
This saves code on our end, end upstream is also more efficient as every
RR is Len-ed only once. With our bin-search this is not guaranteed.

* plugin/file: make non-existent file non-fatal

If the zone file being loaded doesn't exist *and* reload is enabled,
just wait the file to pop up in the normal Reload routine.

If reload is set to 0s; we keep this a fatal error on startup. Aslo fix
the ticker in z.Reload(): remove the per second ticks and just use the
reload interval for the ticker.

Brush up the documentation a bit as well.

- Remove resyncperiod from Kubernetes plugin

The -cpu flag is a weird one (and copied originally from Caddy), it
basically sets GOMAXPROCS which can be *easily* done by just setting
that environment variable. Also with systemd and containerized env you
set this externally *anyway*, so there is little use to do this again in
the binary.

Also the option's help was confusing (i.e. percentage of what?). Remove
the option and supporting files.

This fixes a long standing bug:
fixes: #1609

Load secondary zones in a go-routine; this required another mutex to
protect some fields; I think those were needded anyway because a
transfer can also happen when we're running; we just didn't have a test
for that situation.

The test had to be changed to wait for the transfer to happen at this is
async now.
