To start with, this makes a lot of code context-aware, more changes will move more things into the context structure.

Also, in the case when there's no beacon interval set, program the default into the device (instead of adjusting, which results in the max) since using the max in that case interacts badly with dual-mode/PAN parameters. Also update the PAN parameters accordingly and use the same constant as here.
