I believe I added all the missing pieces for the SRFI-140 (Immutable strings) specification,
including specification of libraries to be provided.  It should now be
more-or-less independent of SRFI-135.

There is still work needed on the preamble, including the abstract, which is
written in reference to SRFI-135.

The implementation is still unfinished. The "invoke" branch of Kawa's git
repository has the necessary skeleton, but many of the procedure are missing.
There is no reference implementation; that might be written as
a wrapper around SRFI-135.
