MP-UMAP v1.0.0

MP-Umap is a collection of libraries that allows multiple processes to share a single file-backed Umap buffer. Just like Umap, it uses user-space page fault handler based on the userfaultfd Linux feature (starting with 4.3 linux kernel). This feature requires a Umap Service to be started and the client applications bind/interact with this service through MP-Umap client API. Presently, this enables sharing of buffer in read-only capacity. The use case is to have a multi-process application accessing a large file through cached pages, i.e. out-of-core execution using memory map.
