unbundle: extract the core logic in another function
The `exchange` module now contains an `unbundle` function that holds the core
unbundle logic. The wire protocol keeps its own unbundle function. It enforces
wireprotocol-specific logic and then calls the extracted function.
This aims at implementing unbundle for localrepo.
