openssl: fix possible SEGV on race between SSLSocket#stop and #connect
* ext/openssl/ossl_ssl.c (ossl_ssl_stop): Don't free the SSL struct
here. Since some methods such as SSLSocket#connect releases GVL,
there is a chance of use after free if we free the SSL from another
thread. SSLSocket#stop was documented as "prepares it for another
connection" so this is a slightly incompatible change. However when
this sentence was added (r30090, Add toplevel documentation for
OpenSSL, 2010-12-06), it didn't actually. The current behavior is
from r40304 (Correct shutdown behavior w.r.t GC., 2013-04-15).
[ruby-core:74978] [Bug #12292]
* ext/openssl/lib/openssl/ssl.rb (sysclose): Update doc.
* test/openssl/test_ssl.rb: Test this.
