    Merge branch 'faster-uuid-gen' into stable #1887

commit ba403e4a7cd2ff5a4d9e4c669ce71c6260fe21a3

    [guid.hpp] GUID::from_string and is_valid_string takes a const char*
    
    boost::uuids::string_generator has operator()(const char*).
    
    thus we can avoid allocating std::string, with a consistent 4% speedup
