wip/kivaloo 1.2.0 NetBSD

Kivaloo (pronounced "kee-va-lieu") is a collection of utilities which together form a data store associating keys of up to 255 bytes with values of up to 255 bytes. It was designed to satisfy the needs of the Tarsnap online backup service for high-performance key-value storage.

At present, kivaloo comprises a block store (lbs) providing log-structured storage within a local filesystem; a key-value store (kvlds) which manages a log-structured B+Tree and services requests upon it from a single connection; and a request multiplexer (mux) which accepts multiple connections and routes requests and responses to and from a single "upstream" connection.
