This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.
Go policy has been single space after periods in comments for some time.
The copyright header template at:
https://golang.org/doc/contribute.html#copyright
also uses a single space.
Make them all consistent.

GODEBUG=netdns=1 prints a one-time strategy decision. (cgo or go DNS lookups)
GODEBUG=netdns=2 prints the per-lookup strategy as a function of the hostname.
The new "netcgo" build tag forces cgo DNS lookups.
GODEBUG=netdns=go (or existing build tag "netgo") forces Go DNS resolution.
GODEBUG=netdns=cgo (or new build tag "netcgo") forces libc DNS resolution.
Options can be combined with e.g. GODEBUG=netdns=go+1 or GODEBUG=netdns=2+cgo.

This change allows LookupAddr to use getnameinfo through cgo for working
together with various name services other than DNS.

This change adds a type addrinfoErrno to represent getaddrinfo,
getnameinfo-specific errors, and uses it in cgo-based lookup functions.
Also retags cgo files for clarification and does minor cleanup.

The unix and windows getaddrinfo calls return a zone with IPv6
addresses. IPv6 link-local addresses returned are only valid on the
given zone. When the zone is dropped, connections to the address
will fail. This patch replaces IP with IPAddr in several internal
resolver functions, and plumbs through the zone.
