Since close errors have been cleaned up in CL 39997,
TestCloseError is failing on Plan 9, because
TCPListener.Close didn't check that the listener
has already been closed before writing the "hangup"
string to the listener control file.
This change fixes TCPListener.Close on Plan 9,
by closing poll.FD before writing the "hangup"
string.
Fixes#20128.

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.

Since CL 22101, network tests are failing on Plan 9
due to the lack of deadline support.
Instead of panicking, we just ignore the deadline
when set.

This change consolidates functions and methods related to TCPAddr,
TCPConn and TCPListener for maintenance purpose, especially for
documentation. Also refactors Dial error code paths.
The followup changes will update comments and examples.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.
This CL doesn't use go/doc to parse. It only addresses // comments.
It was generated with:

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.

Not only by network, transport-layer intermediaries but by
virtualization stuff in a node, it is hard to identify the root cause of
weird faults without information of packet flows after disaster
happened.
This change adds Source field to OpError to be able to represent a
5-tuple of internet transport protocols for helping dealing with
complicated systems.
Also clarifies the usage of Source and Addr fields.

Ideally, those methods should return a copy of the Addr, but
due to the Go 1 API guarantee, we cannot make that change now:
there might exist client code that uses the returned Addr as
map index and thus relies on the fact that different invocation
of the method returns the same pointer. Changing this behavior
will lead to hidden behaviour change in those programs.
