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. Add escript to bootstrap/bin Remove unused variable warning in inet_res Remove unused variable in epmd_port Remove compiler warnings in inet_drv Add SASL test suite Allow same module name in multiple applications if explicitely excluded Fix bugs concerning the option report_missing_types Fix default encoding in SAX parser. re: remove gratuitous "it " in manpage Spelling in (backward *compatibility*) comment. Improve erl_docgen's support for Dialyzer specs and types dialyzer warning on mnesia_tm Add documentation text about majority checking add mnesia_majority_test suite where_to_wlock optimization + change_table_majority/2 bug in mnesia_tm:needs_majority/2 optimize sticky_lock maj. check check majority for sticky locks ...
