build: windows signing should include timestamps

Previously the build artifacts did not include a signed timestamp, so
when the certificate expired the validation of the artifact would fail.
Now we sign against a timestamp server such that the artifact will
always be valid regardless of the disposition of the certificate.

Closes #7360 and #7059.

docs: correct tls docs. server -> client

when a pfx file is passed to tls.connection,
it is the client private key, not the server's private key.

http: do not emit EOF non-readable socket

Socket may become not `readable`, but http should not rely on this
property and should not think that it means that no data will ever
arrive from it. In fact, it may arrive in a next tick and, since
`this.push(null)` was already called, it will result in a error like
this:

    Error: stream.push() after EOF

        at IncomingMessage.Readable.push (_stream_readable.js:123:10)
