openssl: adapt to OpenSSL 1.1.0 opaque structs

* ext/openssl/extconf.rb: Check existence of accessor functions that
  don't exist in OpenSSL 0.9.8. OpenSSL 1.1.0 made most of its
  structures opaque and requires use of these accessor functions.
  [ruby-core:75225] [Feature #12324]

* ext/openssl/openssl_missing.[ch]: Implement them if missing.

* ext/openssl/ossl*.c: Use these accessor functions.

* test/openssl/test_hmac.rb: Add missing test for HMAC#reset.
