New description:
With maxima-as-an-ecl-library and ecl accessible as a library, we can
start interfacing with maxima via a binary library interface.
This should be more efficient and more robust, because expressions
can be transmitted in a much richer format than text and parsing does
not have to recognise error messages and questions (since communication
does not go via STDIN/STDOUT anymore)
----
Status: For as far as we know, all doctest failures are due to changes in
error reporting and different floating point rounding (no string
conversions anymore).
----
This ticket is dependent on #10766, #10773, #10743. Ticket #10818 is
desirable but not essential. Apply:
