libstage: introduce stage_conf_t for stage_new()

stage_new() call sites were getting quite annoying, using compound
literals with designated initializers on a struct makes the call sites
a lot more readable, self-documenting, and often more compact thanks
to the automatic zeroing of omitted members.

I don't particularly like the name, and may switch it later, something
shorter would be nice.
