    bitbake: lib/bb/msg.py: Add filter utilities
    
    Adds generic filter utilities that can be used to filter when the log
    level is greater than or equal to a defined value, or below a defined
    value, as well as a generic function to translate a string to a logging
    level (or bitbake logging level)
