v4.3.0

• fixed issues when compiling with C++11
• fixed and improved cmake build (in and out of source builds, libzmq discovery, fallback to pkg-config and more)
• updated README.md with clear design goals, supported platforms
• official CI support for Linux, MacOS and Windows
• unit tests infrastructure
• test code coverage brought to 77%
• updated code style (more details in .clang-format)

socket_t:

• added support for draft ZMQ_SERVER and ZMQ_CLIENT sockets
• added support for draft ZMQ_RADIO and ZMQ_DISH sockets

poller_t:

• poller_t became thin abstraction layer on zmq_poller_*
• functionality with std::function handlers split and moved to a new active_poller_t in zmq_addon.hpp
• simpler and safer implementation
• made non-copyable, but properly movable
• more consistent and robust error handling
• event type part of handler definition
• fixed a segfault issue when modifying poller_t from a handler
• added empty method indicating presence of registered sockets

context_t:

• added methods for context options: setctxopt(int option_, int optval_) and int getctxopt(int option_)

message_t:

• easier construction from iterable type e.g. std::string, std::array
• added != and == operators and equals method marked as deprecated

multipart_t:

• added an operator<<(std::ostream) to easily print out multipart_t content
