ZMQ_METADATA: Add application metadata properties to a socket
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The _ZMQ_METADATA_ option shall add application metadata to the specified _socket_,
the metadata is exchanged with peers during connection setup. A metadata property is
specfied as a string, delimited by a colon, starting with the metadata _property_
followed by the metadata value, for example "X-key:value".
_Property_ names are restrited to maximum 255 characters and must be prefixed by "X-".
Multiple application metadata properties can be added to a socket by executing zmq_setsockopt()
multiple times. As the argument is a null-terminated string, binary data must be encoded
before it is added e.g. using Z85 (linkzmq:zmq_z85_encode[3]).
NOTE: in DRAFT state, not yet available in stable releases.
