Adaptive string representation

When adding long strings, don't copy them immediately. Instead
build long strings only when their contents are requested.

This allows to build a long string from parts, using a regular
operator+ in linear time. This lets users to worry much less
about using std.join etc.

If indexing the string is mixed with building it using operator+
the behavior can still be quadratic. We may want to address it in
a later change.
