As the code stands today its hard to know which configuration variables are used by which parts of the system. Some are used by the UIs, some by bin/bitbake itself, some by cooker. This patch changes the configuration to just contain the variables cooker uses, and changes bin/bitbake to access the variables it needs directly which hopefully lets us start to untangle this mess.
