New socket option (ZMQ_ROUTER_RAW_SOCK) for ZMQ_ROUTER sockets

Use correct types when returning value in read/write methods

Resolve LIBZMQ-447

    - Created a new option ZMQ_ROUTER_RAW_SOCK
    - Added new raw_encoder and raw_decoder to receive and send messages in raw form to remote client
    - Added test case file tests/test_raw_sock.cpp

    o To create a raw router sock set the ZMQ_ROUTER_RAW_SOCK option
    o ZMQ_MSGMORE flag is ignored for non-id messages
    o To terminate a remote connection send id message followed by zero length data message

Fixed code formatting

resolve issue 456

Do not filter out duplicate subscriptions on the XSUB side of
XSUB/XPUB, so that ZMQ_XPUB_VERBOSE doesn't get blocked by forwarding
devices (as long as the devices all use ZMQ_XPUB_VERBOSE)
