Improve plugin loading architecture

This should be better, maybe the variable names could be better though.

Init is more extensible, we take in a 'board_data' struct on the plugin
end that has everything it needs (mainly function pointers for now).

Then, a 'board' struct is given back to the main Clak runtime, with
everything it needs to know (again, mainly function pointers).

It is a bit weird that the board is not stored with Clak but as a
pointer to the dynamically loaded bit, but not sure.
