wslay: updated to 1.1.0

wslay v1.1.0:
* Fix compilation of examples
  Since 3.4 nettle defines base64_encode_raw like this:
    void base64_encode_raw(char *dst, size_t length, const uint8_t *src);
* check for 0 length before memcpy:
* Skip UTF-8 validation for PMCE fragments
  If the message was marked with rsv1 on the initial frame then we
  should skip utf-8 validation on subsequent continuation frames as
  well.
* Allow RSV1 bit in event-based API for PMCE - RFC 7692
  Add a new function wslay_event_set_allowed_rsv_bits which only accpet
  RSV1 for now (or 0 to disable).
  Skip UTF-8 validation on frames with RSV1 set as it is too early for that.
  Add extended versions of wslay_event_queue_msg functions which also
  take the reserved bits to set for this message.
* fixed missing malloc guard
* Fix argc check.
* CMake support
