WebSockets requires HTTP/1 in practice (no spec or implementations
work over HTTP/2), so if we get an HTTP request that looks like it's
trying to initiate WebSockets, use HTTP/1, like browsers do.
This is part of a series of commits to make WebSockets work over
httputil.ReverseProxy. See #26937.

Panic if an http Handler does:

I previously made it kinda work in https://golang.org/cl/19130 but
there's no good way to fake it in HTTP/2, and we want HTTP/1 and
HTTP/2 behavior to be the same, regardless of what programs do.
Currently HTTP/2 omitted the :status header altogether, which was a
protocol violation. In fixing that, I found CL 19130 added a test
about bogus WriteHeader values with the comment:
// This might change at some point, but not yet in Go 1.6.

Go's http1 implementation originally had a mechanism to send HTTP
trailers based on pre-declaring the trailer keys whose values you'd
later let after the header was written.
http2 copied the same mechanism, but it was found to be unsufficient
for gRPC's wire protocol. A second trailer mechanism was added later
(but only to http2) for handlers that want to send a trailer without
knowing in advance they'd need to.
Copy the same mechanism back to http1 and document it.

The Transport's automatic gzip uncompression lost information in the
process (the compressed Content-Length, if known). Normally that's
okay, but it's not okay for reverse proxies which have to be able to
generate a valid HTTP response from the Transport's provided
*Response.
Reverse proxies should normally be disabling compression anyway and
just piping the compressed pipes though and not wasting CPU cycles
decompressing them. So also document that on the new Uncompressed
field.
Then, using the new field, fix Response.Write to not inject a bogus
"Connection: close" header when it doesn't see a transfer encoding or
content-length.

This makes sure the net/http package never attempts to transmit a
bogus header field key or value and instead fails fast with an error
to the user, rather than relying on the server to maybe return an
error.
It's still possible to use x/net/http2.Transport directly to send
bogus stuff. This change only stops h1 & h2 usage via the net/http
package. A future change will update x/net/http2.
This change also moves some code from request.go to lex.go, which in a
separate future change should be moved so it can be shared with http2
to reduce code bloat.

If a user starts two HTTP requests when no http2 connection is
available, both end up creating new TCP connections, since the
server's protocol (h1 or h2) isn't yet known. Once it turns out that
the server supports h2, one of the connections is useless. Previously
we kept upgrading both TLS connections to h2 (SETTINGS frame exchange,
etc). Now the unnecessary connections are closed instead, before the
h2 preface/SETTINGS.

ConnectionState.NegotiatedProtocol, we have to gurantee that the TLS
handshake has been done before we look at the ConnectionState. So add
that check after the DialTLS hook. (we never documented that users
have to call Handshake, so do it for them, now that it matters)

Updates bundled http2 to golang.org/x/net git rev 1ade16a545 (for

The http1 behavior changes slightly: if req.Header["User-Agent"] is
defined at all, even if it's nil or a zero-length slice, then the
User-Agent header is omitted. This is a slight behavior change for
http1, but is consistent with how http1 & http2 do optional headers
elsewhere (such as "Date", "Content-Type"). The old behavior (set it
explicitly to "", aka []string{""}) still works as before. And now
there are even tests.
