In lib/dns.js, use `isIP()` instead of `isIPv4()` for determining the
`family` property in `lookup()`. If an invalid IP address is returned,
the `family` currently provided is `6`. With this change, it will be
`0`. Update documentation to reflect this.

Before this commit, Node.js left it up to the system resolver or c-ares.
Leaving it to the system resolver introduces platform differences
because:
* some support IDNA 2008
* some only IDNA 2003 (glibc until 2.28), and
* some don't support IDNA at all (musl libc)
c-ares doesn't support IDNA either although curl does, by virtue of
linking against libidn2. Upgrading from libidn1 to libidn2 in order
to get proper IDNA 2008 support was the fix for curl's CVE-2016-8625.
libidn2 is not an option (incompatible license) but ICU has an IDNA API
and we already use that in one place. For non-ICU builds, we fall back
to the bundled punycode.js that also supports IDNA 2008.

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.

about the differences of errors that we throw into the user land.
- Move util._errnoException and util._exceptionWithHostPort
into internal/errors.js and simplify their logic so it's
clearer what the properties these helpers create.
- Move the errnoException helper in dns.js to internal/errors.js
into internal/errors.js and rename it to dnsException. Simplify

Removes a few lines of C++ code while making `isIPv4()` about 3x faster.
`isIPv6()` and `isIP()` for the IPv6 case stay about the same.
I removed the homegrown `isIPv4()` in lib/dns.js that utilized a lookup
table. It is in fact a little faster than the new `isIPv4()` function
but:
1. The difference is only measurable at around 10M iterations, and
2. The function is a "probably IPv4" heuristic, not a proper validator.
