Goroutine 1:
  Call Read on read half of pipe, entering pipeHalf.rw.
  Check ioclosed field, which is false.
  Send data to p.c1
  Wait for response on p.c2.

Goroutine 2:
  Call Close on read half of pipe, entering pipeHalf.close.
  Set closed field.
  Send error to p.cclose.
  Set ioclosed field.
  Send 1 to p.done.
  Return and exit goroutine.

Goroutine 3:
  This is the goroutine running pipe.run, and for some reason
  it has started late.
  Read error from p.rclose; set rerr and continue.
  Read 1 from p.done; increment ndone and continue.
  Read data from r1 (sent by goroutine 1); set r1 = nil and continue

Now goroutine 1 is waiting for a response, and goroutine 3 is
waiting for something else to happen.

This patch fixes the race by having the runner check whether
the read half is closed when it is asked for read data, and
similarly for the corresponding race on the write half.

This patch also fixes the similar race in which ndone gets
bumped up to 2 while there is a reader or writer waiting.

There is still another race to fix.  It is possible for the
read half and the write half to both be closed, and for the
runner goroutine to exit, all before the runner goroutine sees
the request from a reader.  E.g., in the above, have goroutine
2 also close the write half, and have goroutine 3 see both
done messages before it sees the request from goroutine 1.

SNI (Server Name Indication) is a way for a TLS client to
indicate to the server which name it knows the server by. This
allows the server to have several names and return the correct
certificate for each (virtual hosting).

PeerCertificates returns the list of certificates presented by
server.

        OCSP is the preferred X.509 revocation mechanism. X.509 certificates
        can contain a URL from which can be fetched a signed response saying
        "this certificate is valid until $x" (where $x is usually 7 days in the
        future). These are called OCSP responses and they can also be included
        in the TLS handshake itself ("OCSP stapling")

strings.ToTitle converts all characters to title case, which for consistency with the
other To* functions it should continue to do.  This CL adds string.Title, which
does a proper title-casing of the string.
A similar function for package bytes will follow once this is settled.
