Bring the local copy of ruby/openssl in sync with the upstream gem

Note that many of these have already been applied to ruby.git and don't
appear in the file changes of this commit.

Ruby 2.7 deprecates taint and it no longer has an effect.
The lack of taint support should not cause a problem in
previous Ruby versions.

to suppress a warning in OpenBSD.

```
ossl_ssl.c:938:31: warning: incompatible pointer types passing 'SSL_SESSION *(SSL *, unsigned char *, int, int *)' (aka 'struct ssl_session_st *(struct ssl_st *, unsigned char *, int, int *)') to parameter of type 'SSL_SESSION *(*)(struct ssl_st *, const unsigned char *, int, int *)' (aka 'struct ssl_session_st *(*)(struct ssl_st *, const unsigned char *, int, int *)') [-Wincompatible-pointer-types]

It's unlikely anyone would actually hit these.  The methods are
private, you only hit this code path if calling these methods
before performing the SSL connection, and there is already a
verbose warning issued.

After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is
dangerous and should be extinct.  This commit makes rb_iterate free
from ANYARGS.
