Chris Larson 68bd406962 Add initial bitbake-layers script

This script has subcommands which operate against your bitbake layers, either
displaying useful information, or acting against them.  Currently, it only
provides a show_appends command, which shows you what bbappends are in effect,
and warns you if you have appends which are not being utilized.

Currently, a bug exists when using this due to the DataContext stuff, but I'm
not certain as to the root cause, it appears to be the bb package relying
implicitly on the way the bitbake script does things.  A fix for that issue
will be forthcoming, as will further subcommands.
