mysql/mysqld/mysql_install_db writes messages to STDERR that probaly should be written to STDOUT

mysql/mysqld/mysql_install_db do write a lot of "[Note]" messages out to STDERR, and only some messages to STDOUT.

It seems like most of these info messages should be written to STDOUT and not to STDERR judging from their importance.

The problem is discussed more in detail at the following link, with examples.

Verified in 5.5.33.
Problem seems to be solved in 10.1.x versions, tested 10.1.13.
