Subject: [PATCH] Marking a bunch of AsyncSSLSocket methods as "const".

Summary: folly::AsyncSSLSocket class has a number of "get..." methods which don't change the object's state, but are not marked as "const". As a result these methods can't be called on objects passed through const pointer or referrence. Adding "const" modificator for these methods.
