      Switch to Guile-JSON 3.x. · 0bd4ecd7
      Ludovic Courtès authored
      Guile-JSON 3.x is incompatible with Guile-JSON 1.x, which we relied on
      until now: it maps JSON dictionaries to alists (instead of hash tables),
      and JSON arrays to vectors (instead of lists).  This commit is about
      adjusting all the existing code to this new mapping.
      * jupyter/kernels.scm (kernel-arguments): Use 'assoc-ref' instead of
      'hash-ref'; pass JSON array through 'vector->list'.

      * jupyter/kernels.scm (run-kernel): Remove 'uuid' parameter and add
       #:identity parameter.  Do not set ZMQ_IDENTITY on SOCKET-SHELL when

      Ludovic Courtès authored
      This avoids the occasional string decoding error for byte streams that
      were not actual UTF-8 strings.
      This is based on commit fbab29d738b46d8637579ccec93be49520a4606f ("Fixed
      a bug when the kernel could not send kernel_info (1 minute pause after
