context: improve settings and defaults

Browse source 
Make structure with defaults that holds the defaults as they are loaded
from the config file or initialized with default values.

Copy this structure to a settings version that is used at runtime.

Add a force-quantum and force-rate field in the settings that can be
used to force a quantum and samplerate if != 0.
