Bug#7853 (mysqlbinlog does not accept input from stdin)

  The utility 'mysqlbinlog' now accepts input from stdin. It can 
  now be used to read the output from, e.g., 'zcat' or other utility.


client/mysqlbinlog.cc:
  Reading from stdin instead of stdout [sic].
  Not repositioning manually since my_b_read does that correctly.
mysql-test/r/mysqlbinlog.result:
  Adding tests for reading from stdin.
mysql-test/t/mysqlbinlog.test:
  Adding tests for reading from stdin.
