til_stream: introduce stream iterator et al
In order to implement something like a rocket module there needs to be a way to iterate the pipes in the stream, and take owernship of them when not already owned by rocket. The way rocket's API works is you lookup tracks by name at runtime. The rocket module will be a meta module that calls into another module for rendering, arbitrarily configured via a rocket setting a la checkers::fill_module. So it won't be until the underlying modules do some rendering that their taps get their respective pipes established in the stream. Then the rocket module can look at all the pipes and for any it doesn't own yet, it can get the tracks for those names and take ownership while stowing the track handle in owner_foo for the pipe. While iterating all the pipes, the pipes already owned will have the tracks readily available which can produce the values to stick in the tap. Something like that anyways, the til_stream_t api changes in this commit are all preparatory for a rocket module.
