My previous https://golang.org/cl/22101 to add context throughout the
net package broke Plan 9, which isn't currently tested (#15251).
It also broke some old unsupported version of Windows (Windows 2000?)
which doesn't have the ConnectEx function, but that was only found
visually, since our minimum supported Windows version has ConnectEx.
This change simplifies the Windows and deletes the non-ConnectEx code
path. Windows 2000 will work even less now, if it even worked
before. Windows XP remains our minimum supported version.
Specifically, the previous CL stopped using the "dial" function, which
0intro noted:
https://github.com/golang/go/issues/15333#issuecomment-210842761
This CL removes the dial function instead and makes plan9's net
implementation respect contexts, which likely fixes a number of
t.Skipped tests. I'm leaving that to 0intro to investigate.
In the process of propagating and respecting contexts for plan9, I had
to change some signatures to add contexts to more places and ended up
pushing contexts down into the Go-based DNS resolution as well,
replacing the pure-Go DNS implementation's use of "timeout
time.Duration" with a context instead.

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.

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.
