For invalid values and negative numbers, 0 is used.
For numbers greater than 15, 15 is used.

Fixes the darwin/arm builder, which has a special test runner which
makes the assumption that tests never use testdata from another
package.
This looks large, but it's no more space in git.

Parsing literal IPv6 address with zone identifier is already supported
when not using cgo. This change enables it when using cgo too.

The previous change for #12806 modified internal lookup tables and made
LookupAddr return forcibly lowercased host names by accident.
This change fixes the issue again without any behavioral change for
LookupAddr and adds missing test cases for lookupStaticHost and
lookupStaticAddr.
Updates #12806.
Fixes#13359.

The native Go host resolver was behaving differently than libc
and the entries in the /etc/hosts were handled in a case sensitive
way. In order to be compatible with libc's resolver, /etc/hosts
lookups must be case-insensitive.
Fixes#12806.

This change fixes incorrect parsing of literal IP addresses in local
database when the addresses contain IPv6 zone identifiers, are in
dotted-decimal notation or in colon-hexadecimal notation with leading
zeros.
https://golang.org/cl/5851 already fixed the code path using getaddrinfo
via cgo. This change fixes the remaining non-cgo code path.
Fixes#8243.
Fixes#8996.

If the machine's network configuration files (resolv.conf,
nsswitch.conf) don't have any unsupported options, prefer Go's DNS
resolver, which doesn't have the cgo & thread over.
It means users can have more than 500 DNS requests outstanding (our
current limit for cgo lookups) and not have one blocked thread per
outstanding request.
