    Bug 16166: Improve L1 cache performance and safety
    
    Bug 16044 introduced two-level caching mechanism to Koha::Cache. By
    default, get_from_cache() returns a deep copy of the data structures
    stored in L1 cache (aka "safe mode"). For extremely big and/or complex
    data structures (like MARC framework hash-of-hashes-of-hashes returned
    by GetMarcStructure() ), deep-cloning is currently sub-optimal;
    this patch addresses that particular issue. It also provides an
    ability to intermix "safe" and "unsafe" cache feches, in such
    way that they don't interfere with each other (i.e., eliminating
    the risk involved with "unsafe" calls possibly compromising
    further "safe" calls).
    
    Test plan:
    
    1) apply patch
    2) flush L2 cache if necessary (restart memcached daemon)
    3) profile GetMarcStructure() calls before / after patch, e.g. by
    running some script which calls it often (like catalogue search
    w/ XSLT processing turned on, etc.) - GetMarcStructure() should be
    faster than before, in all possible circumstances (eg. 18 msec
    per call -> 10 msec p/call)
    4) after testing, before returning to the master branch, flush L2 cache
    again (restart memcached daemon) - otherwise all system preferences
    returned from L2 cache would be suffixed with '-CF0'
