Solution: Constuctor taking generic ranges including
string literals includes the null terminated char in
the message. Deprecate function and add overloads
for strings.
Until now, we only assigned the _handle on
`zmq::socket_t::operator=(socket_t&&)`. This manifests when trying to
monitor a socket initialized by that constructor.
To avoid changing the public interface of the socket_t class, we tested
for the specific monitor usecase, since it's the only class accessing
zmq::socke_t::ctxptr.
NOTE: When running the new unit-test without the fix, it might hang on
`zmq_socket_monitor(socket_, NULL, 0)`. We haven't figured out the cause
for that, but we deemed it unimportant (or at least out of scope).
This commit fixes a regression introduced in a3e5b54c3 (Problem: Socket
options lack type-safety (#393)).
It addresses the following error reported when building the project
on macOS 10.11.6.
Errors like the following:

Solution: Implement a type for each socket option.
Each option has an associated type, therefore they
can't be simply defined as an enum class.
Use new sockopt getter in test util
Add socket option get function for strings and tests
* Problem: Macros not defined in older versions
Solution: Guard usage of libzmq macros
* Test older version of libzmq with C++11 or later
* Use a slightly newer libzmq version
Solution: Define an enum class for the context options

Solution: Add shutdown(). This function is required
for clean termination of the zmq context in multi-threaded
applications where sockets are used in threads. In particular
if blocking operation are used and if sockets can be created
at any time.
* Improve tests and documentation
Solution: Remove architechture checks from cmake version file
Since this is a header only library there is no need to check for 32 vs 64bits.
