Solution: add man pages/sections for:

 * ZMQ_SERVER
 * ZMQ_CLIENT
 * ZMQ_THREADSAFE
 * zmq_msg_routing_id
 * zmq_msg_set_routing_id

Enable install of man pages when BUILD_DOC is not set by shifting INSTALL_MAN outside of BUILD_DOC's if/endif

Solution: as libzmq already provides this across all platforms,
expose an atomic counter API. I've not wrapped atomic pointers,
though someone who needs this may want to do so.

There is zero benefit to this, and some confusion due to the special
case nature of this man page.

Solution: delete the zmq_epgm man page.

Solution: fix Makefile.am

As per Richard Sharpe on zeromq-dev.

As libzmq is compiled with optional transports and security mechanisms,
there is no clean way for applications to determine what capabilities
are actually available in a given libzmq instance.

Solution: provide an API specifically for capability reporting. The
zmq_has () method is meant to be open ended. It accepts a string so
that we can add arbitrary capabilities without breaking existing
applications.

zmq.h also defines ZMQ_HAS_CAPABILITIES when this method is provided.

- also removed deprecated man pages from Makefile
- they remain in repository for reference

- spaces instead of tabs for indentation
- fixed levels under EXAMPLE USAGE
- added to Makefile.am

* Added new man page for this
* Added test case, in tests/test_security_curve.cpp
* Noted in zmq_utils.h that these methods are documented

* Removed redundant Z85 code and include files from project
* Simplified use of headers in test cases (now they all just use testutil.hpp)
* Export zmq_z85_encode() and zmq_z85_decode() in API
* Added man pages for these two functions

* ZMQ_PLAIN_SERVER, ZMQ_PLAIN_USERNAME, ZMQ_PLAIN_PASSWORD options
* Man page changes to zmq_setsockopt and zmq_getsockopt
* Man pages for ZMQ_NULL, ZMQ_PLAIN, and ZMQ_CURVE
* Test program test_security

in order to avoid logical collisions with pre-existing notions of context destruction in bindings (czmq, pyzmq).

Significantly reworked the monitoring infrastructure with a more granular per socket API and to play well with monitoring endpoints in application threads

* zmq_device is now a wrapper that calls zmq_proxy
* zmq_proxy adds capture socket

* Implemented new ctx API (_new, _destroy, _get, _set)
* Removed 'typesafe' macros from zmq.h
* Added support for MAX_SOCKETS (was tied into change for #337)
* Created new man pages

 - reverted commit 941be8d2.
 - fixed zmq_device implementation for latest socket_base class
 - added back zmq_device.3 man page

* Added zmq_msg_poke for orthogonality
* Added zmq_msg_more for simplicity
* Fixed up man pages and test program

The new function allows to retrieve options (flags)
from zmq_msg_t.
