MDEV-22441 implement a generic way to change a value of a variable in a scopebb-10.8-MDEV-22441-scoped-variable
Example:
{
auto _= make_scope_value(var, tmp_value);
}
make_scope_value(): a function which returns RAII object which temporary
changes a value of a variable
detail::Scope_value: actual implementation of such RAII class.
It shouldn't be used directly! That's why it's inside a namespace detail.
