defined:

* ipc - the library supports the ipc:// protocol
* pgm - the library supports the pgm:// protocol
* tipc - the library supports the tipc:// protocol
* norm - the library supports the norm:// protocol
* curve - the library supports the CURVE security mechanism
* gssapi - the library supports the GSSAPI security mechanism
* draft - the library is built with the draft api

When this method is provided, the zmq.h header file will define
ZMQ_HAS_CAPABILITIES.

RETURN VALUE
------------
The _zmq_has()_ function shall return 1 if the specified capability is
provided. Otherwise it shall return 0.
