The previous implementation spawned an extra goroutine to handle
rechecking resolv.conf for changes.
This change eliminates the extra goroutine, and has rechecking
done as part of a lookup. A side effect of this change is that the
first lookup after a resolv.conf change will now succeed, whereas
previously it would have failed. It also fixes rechecking logic to
ignore resolv.conf parsing errors as it should.

The Transport's writer to the remote server is wrapped in a
bufio.Writer to suppress many small writes while writing headers and
trailers. However, when writing the request body, the buffering may get
in the way if the request body is arriving slowly.
Because the io.Copy from the Request.Body to the writer is already
buffered, the outer bufio.Writer is unnecessary and prevents small
Request.Body.Reads from going to the server right away. (and the
io.Reader contract does say to return when you've got something,
instead of blocking waiting for more). After the body is finished, the
Transport's bufio.Writer is still used for any trailers following.
A previous attempted fix for this made the chunk writer always flush
if the underlying type was a bufio.Writer, but that is not quite
correct. This CL instead makes it opt-in by using a private sentinel
type (wrapping a *bufio.Writer) to the chunk writer that requests
Flushes after each chunk body (the chunk header & chunk body are still
buffered together into one write).

FileConn and FilePacketConn APIs accept user-configured socket
descriptors to make them work together with runtime-integrated network
poller, but there's a limitation. The APIs reject protocol sockets that
are not supported by standard library. It's very hard for the net,
syscall packages to look after all platform, feature-specific sockets.
This change allows various platform, feature-specific socket descriptors
to use runtime-integrated network poller by using SocketConn,
SocketPacketConn APIs that bridge between the net, syscall packages and
platforms.
New exposed APIs:
pkg net, func SocketConn(*os.File, SocketAddr) (Conn, error)

When running the client header timeout test, there is a race between
us timing out and waiting on the remaining requests to be serviced. If
the client times out before the server blocks on the channel in the
handler, we will be simultaneously adding to a waitgroup with the
value 0 and waiting on it when we call TestServer.Close().
This is largely a theoretical race. We have to time out before we
enter the handler and the only reason we would time out if we're
blocked on the channel. Nevertheless, make the race detector happy
by turning the close into a channel send. This turns the defer call
into a synchronization point and we can be sure that we've entered
the handler before we close the server.

Old Darwin versions also lack TCP_KEEPINTVL, but the code tries to set

Oracle might assign the number illumos uses for TCP_KEEPINTVL to a

multiple addresses are supported.
The "first" method returns the first address matching some condition
(e.g. "is it IPv4?"), primarily to support legacy code that can't handle
multiple addresses.
The "partition" method splits an addrList into two categories, as
defined by some strategy function. This is useful for implementing
Happy Eyeballs, and similar two-channel algorithms.
Finally, internetAddrList (formerly resolveInternetAddr) no longer
mangles the ordering defined by getaddrinfo. In the future, this may

There was a logical race in Transport.RoundTrip where a roundtrip with
a pending response would race with the channel for the connection
closing. This usually happened for responses with connection: close
and no body.
We handled this race by reading the close channel, setting a timer
for 100ms and if no response was returned before then, we would then
return an error.
This put a lower bound on how fast a connection could fail. We couldn't
fail a request faster than 100ms.
Reordering the channel operations gets rid of the logical race. If
the readLoop causes the connection to be closed, it would have put
its response into the return channel already and we can fetch it with
a non-blocking receive.

When making a request to an IPv6 address with a zone identifier, for
exmaple [fe80::1%en0], RFC 6874 says HTTP clients must remove the zone
identifier "%en0" before writing the request for security reason.
This change removes any IPv6 zone identifer attached to URI in the Host
header field in requests.

Using IPv6 link-local addresses to make connections between on-link
nodes is useful for small distributed applications but it requires zone
identifiers to distinguish a correct IP link. It's the same for
transports using URI for destination discovery such as HTTP, WebSocket.
This change allows Parse, ParseRequestURI functions and String method of
URL to parse/return a literal IPv6 address followed by a zone identifier
within a URI as described in RFC 6874.
