This fully exposes the store internals for #19 and are final preparations for removing the legacy store interface.
This change also fixes a potential deadlock in the handle initialisation mkdir failure path. This however is never reachable in hakurei as the store is never accessed concurrently.

It is completely nonsensical and highly error-prone to have multiple implementations of this in the same build. This should be switched at compile time instead therefore the split packages are pointless.
