Now about making an int with flags here instead of a number of boolean
arguments. is_server could be a flag as well.

Because we would just pack them all up before calling the function, and unpack
them all in the called function, using flag definitions on the bits that need to
be added to the Dart and C++ files, and kept in sync between them, I think it is
clearer, and not that much less efficient, to just pass them explicitly.  We can
always change this later, especially if we add more flags.
