New driver API function: config_list() 

This takes an sr_config key and returns a list of possible values for
that key to be submitted with config_set(). The format of the list and
its contents is dependent on the key.

This will replace the SR_DI_* keys that returned such a list before,
such as SR_DI_SAMPLERATES.
