Code cleanup

Simplify implementation of DEALER socket

Addded ROUTER-ROUTER (back) as valid combination

Cmake minor version labeling and sync with 3.x

Code cleanup

Fix raw mode on reconnect

Zeromq shall never send/receive socket identifiers for sockets in raw
mode. The existing implementation breaks this requirement after
reconnection.

Add test when the zeromq socket connects to a TCP socket.
The test now fails due to bug in the zeromq library.

session_base: code cleanup

- add unlikely hints
- drop unnecessary assertion
- style fixes

There is no need to require the 'more' flag in the provided message

Renamed ZMQ_ROUTER_RAW_SOCK to ZMQ_ROUTER_RAW

comments in the C API header.

Update builds/msvc/libzmq/libzmq.vcproj

Without the LinkDLL statement, command-line compile using vcbuild attempts to compile EXE and complains about entrypoint
The LinkDLL statement forces the linker to produce desired output
