Implement copy ctor/assignment for xpath_variable_set
xpath_variable_set is essentially an associative container; it's about time it
became copyable.
Implementation is slightly tricky due to out of memory handling. Both copy ctor
and assignment operator have strong exception guarantee (even if exceptions are
disabled! which translates to "roll back on allocation errors").
