Roman Nozdrin 4c26e4f960 MCOL-4912 This patch introduces Extent Map index to improve EM scaleability ...

EM scaleability project has two parts: phase1 and phase2.
        This is phase1 that brings EM index to speed up(from O(n) down
        to the speed of boost::unordered_map) EM lookups looking for
        <dbroot, oid, partition> tuple to turn it into LBID,
        e.g. most bulk insertion meta info operations.
        The basis is boost::shared_managed_object where EMIndex is
        stored. Whilst it is not debug-friendly it allows to put a
        nested structs into shmem. EMIndex has 3 tiers. Top down description:
        vector of dbroots, map of oids to partition vectors, partition
        vectors that have EM indices.
        Separate EM methods now queries index before they do EM run.
        EMIndex has a separate shmem file with the fixed id
        MCS-shm-00060001.
