The network encapsulation library, nmsg, version 1.0.0 is released.
This release deprecates Crossroads I/O (libxs) support in favor of
ZeroMQ (libzmq). Note command-line updates enabling ZeroMQ socket
connections for nmsgtool, as described in its man page. In addition
the treatment of unknown rrtypes was amended for nmsgtool JSON
output. In detail:

  Replace libXS with ZeroMQ and associated calls.

  Developer API functions nmsg_input_open_xs(),
  nmsg_input_open_xs_endpoint(), nmsg_io_add_input_xs_channel(),
  nmsg_output_open_xs(), and nmsg_output_open_xs_endpoint() are
  deprecated and replaced with respectively: nmsg_input_open_zmq(),
  nmsg_input_open_zmq_endpoint(), nmsg_io_add_input_zmq_channel(),
  nmsg_output_open_zmq(), and nmsg_output_open_zmq_endpoint().

  Update nmsgtool command-line options: --readzchan replaces --readzsock,
  --writezsock replaces --writexsock, --readzsock replaces --readxsock.

  Change format of unknown rrtypes in nmsgtool JSON output to "TYPE"
  followed by number.
