Code refactorization finished for allocate_log and deallocate_log.

    Made some basic tests for every refactorization. The basic_perf test showed
    strange results when using nq::memlib::New which happens to go 20 to 25%
    faster than a simple new (WITH NO LOGGING!).
    This is true only with the -O3 compiler option (without ~75% perf_loss), so
    maybe some allocations are not made ?
    Also NQ_NEW(Domain), always makes a 7 to 12 % perf_loss (which seems logical),
    so maybe I'm missing some points in the between:
    new is called   --and--
    operator new() is resolved
