Bug#23735 mysqlbinlog client fails when reading binlog from stdin

 - Windows opens stdin in text mode by default. Certain characters
   such as CTRL-Z are interpeted as events and the read() method
   will stop. CTRL-Z is the EOF marker in Windows. to get past this
   you have to open stdin in binary mode. Setmode() is used to set
   stdin in binary mode. Errors on setting this mode result in
   halting the function and printing an error message to stderr.
