Warnings are added to net_server.cc when global_system_variables.log_warnings >= 4. When the above condition holds then: - All communication errors from net_serv.cc is also written to the error log. - In case of a of not being able to read or write a packet, a more detailed error is given. Other things: - Added detection of slaves that has hangup to Ack_receiver::run() - vio_close() is now first marking the socket closed before closing it. The reason for this is to ensure that the connection that gets a read error can check if the reason was that the socket was closed. - Add a new state to vio to be able to detect if vio is acive, shutdown or closed. This is used to detect if socket is closed by another thread. - Testing of the new warnings is done in rpl_get_lock.test - Suppress some of the new warnings in mtr to allow one to run some of the tests with -mysqld=--log-warnings=4. All test in the 'rpl' suite can now be run with this option. - Ensure that global.log_warnings are restored at test end in a way that allows one to use mtr --mysqld=--log-warnings=4.
