Merge branch 'dev' of super:otp into dev
* 'dev' of super:otp: (166 commits)
Corrected documentation error and added examples to Users Guide
In TLS 1.1, failure to properly close a connection no longer requires that a session not be resumed. This is a change from TLS 1.0 to conform with widespread implementation practice. Erlang ssl will now in TLS 1.0 conform to the widespread implementation practice instead of the specification to avoid performance issues.
