- use SSL_peek instead of looping with
  has_buffered_data().

This fixes t/security/CVE-2009-3555.t where
has_buffered_data() doesn't help, because it
finds the buffered data and doesn't call
SSL_read(), so the reneg handshake isn't
triggered. SSL_peek() for 0 bytes seems to
reliably trigger the reneg in every case.

No more polling/sleeping. The code for the
OpenSSL 1.1.0 case is now again very close to
the pre 1.1.0 case.

Still need to run the full test suite with a
clean build.

  certificate verification of OpenSSL returned
  ok=1.

The old compatibility macro check no longer works,

ifndef is not the correct check.

- partial support for renegotiations.
  - Not a good design, need to poll until
    renegotitation has finished.
  - Loop criterion not right, if no client certs
    will be send.
  - Also doesn't work for EC or DH ciphers.
    Unclear how to fix with current 1.1.0
    API.

  The function no longer exists in 1.1.0.
