This patch reworks several structures: - Fulfill and reject reactions are combined into one collection. The values in this collection are compressed: a capability followed by an optional fulfill and reject functions. - Fulfill and reject reactions are directly stored, no need to allocate an object for them. - The job queue directly stores its items, this saves a pointer to the value, and the callback is replaced by an uint8 type. - Promise status and already resolved is stored in extra_info.
