- Add 'set_default' functions to obs-data.*. These functions ensure that a paramter exists and that the parameter is of a specific type. If not, it will create or overwrite the value with the default setting instead. These functions are meant to be explicitly called before using any of the 'get' functions. The reason why it was designed this way is to encourage defaults to be set in a single place/function. For example, ideal usage is to create one function for your data, "set_my_defaults(obs_data_t data)", set all the default values within that function, and then call that function on create/update, that way all defaults are centralized to a single place. - Ensure that data passed to sources/encoders/outputs/etc is always valid, and not a null value. - While I'm remembering, fix a few defaults of the main program config file data.
