resource-manager: Add API for fine-tuned event listening

The syscommon_resman_subscribe_resource_event() has been split into
3 variants, each of which can narrow down the range of events that
we want to listen to.
- syscommon_resman_subscribe_event(...)
  : It is identical to the existing one. Listen any events from any
    type of resources.

- syscommon_resman_subscribe_resource_event(resource_type, ...)
  : Listen any changes of attribute from specific type of resources.

- syscommon_resman_subscribe_resource_attribute_event(resource_type,
     attr_mask, ...)
  : Listen change of specific attributes from specific type of resources.

In addition, the event callback has been changed to receive an additional
parameter, void *user_data.
