Andrew Harding b90544c9b0 openssl 1.1.x support
- created a uniform shim layer for the Go code to invoke that does the
  right thing depending on the version of openssl. functions that have
  yet to be moved can be done so as needed.

- fixed the incorrect use of X509_STORE_CTX_get_app_data in verify_cb to
  pull out the SSL object from the x509 store context, which causes
  crashes when the SSL object index happens to not be zero.

- fix engine not being passed to HMAC_Init_ex

- fix HMAC tests not checking for failures with NewHMAC
