Import the master branch of ruby/openssl for preparing to release openssl-2.2.0

* ext/openssl/ossl_asn1.c (Init_ossl_asn1): prefer
  `rb_gc_register_mark_object`, which is better for constant
  objects, over `rb_gc_register_address` for global/static
  variables which can be re-assigned at runtime.  [Bug #16196]

* ext/openssl/ossl_asn1.c (Init_ossl_asn1): register the static
  variable to grab an internal object, before creating the object.
  otherwise the just-created object could get collected during the
  global variable list allocation.  [Bug #16196]

Sync with the current tip of master branch, 62436385306c of

Init functions are called only once, cache is useless.
