Add class __versa_string, a versatile "basic_string-type" class:
an additional, non-standard, template parameter allows to specify
the preferred base class. Two are provided: __rc_string_base,
which implements a behavior very similar to our standard string,
and __sso_string_base, not reference-counted and optimized for
short strings.
