- removed unnecessary malloc
- spaces, not tabs to indent
- renamed control states to be more logical
- renamed SUSPEND to PAUSE, feels more accurate
- fixed indentation, which was off in places

Copyrights had become ads for Sustrik's corporate sponsors, going against the original
agreement to share copyrights with the community (that agreement was: one line stating
iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads
is also unfair to the many individual authors. I've removed ALL corporate title from
the source files so the copyright statements can now be centralized in AUTHORS and
source files can be properly updated on an annual basis.

These two headers also include zmq.h somewhere in their dependency
chain, so must be included after poll.h is included for builds to work
on AIX.

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

Copy logic from zmq.cpp into device.cpp for getting poll.h included.

Ensure that zmq.h is included *after* poll.h in both zmq.cpp and
device.cpp.

+ fix whitespace errors
+ drop some unnecessary parens

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

Devices are basically applications on top of 0MQ stack. They
should reside in separate libraties.
