We can `dns.lookup` a falsy `hostname` like `dns.lookup(false)`
for the reason of backwards compatibility long before(see #13119
for detail). This behavior is undocumented and seems useless in
real world apps.
We could also make invalid `hostname` throw in the future and the
change might be semver-major.

The current message says 'Port should be > 0' meaning '0' is an
invalid value. You can pass '0' to get a random port from the system.
The correct message for this error is 'Port should be >= 0'.

To reduce the risk of mistakes and make writing tests that involve

Issue 1: make invalid setServers yield uniform error
Behavior:
dns.setServers throws a null pointer dereference on some inputs.
Expected behavior was the more pleasant
TypeError [ERR_INVALID_IP_ADDRESS] ...
Root cause(s?):
- Dereferencing the result of a regex match without confirming
that there was a match.
- assuming the capture of an optional group (?)
Solution:
Confirm the match, and handle a missing port cleanly.
Tests: I added tests for various unusual inputs.
Issue 2: revise quadratic regex in setServers
Problem:
The IPv6 regex was quadratic.
On long malicious input the event loop could block.
The security team did not deem it a security risk,
but said a PR was welcome.
Solution:
Revise the regex to a linear-complexity version.
Tests:
I added REDOS tests to the "oddities" section.
