Sending actions to self is useful because calling post_action() from
within an action handler will not actually trigger the action. Instead,
it will defer delivery of the action. Allowing sending actions to self
will allow to add another action, in deterministic order, and the
execution of another action handler.
A small modification to rfnoc::action_info makes it polymorphic, and
instead of serializing data structures into a string, this allows
creating custom action objects and identifying them via RTTI. The stream
command action object is a good example for how to use this, so all the
usages of stream command action objects were converted to this scheme.
- Added action_info class
- Allow to send actions from node to node
- Allow to post actions into nodes
- Allow to set default forwarding policies
- Added unit tests
