Problem: no udp/multicast support in zeromq

Problem: radio/dish class broke Windows builds

Solution: add these new classes to MSVC project files

problem: radio-dish is still hacky

problem: request socket state machine check is not running

Problem: copyright year is still 2015

Solution: update to 2016

problem: pub/sub pattern in zeromq is complicated and not thread safe

stop previous monitor socket before starting new one

avoids leaking sockets due to multiple monitor calls on one socket

Alternative: raise error (not sure what errno; EADDRINUSE?) if collision detected; force manual stop.

Family is not set when resolving NIC on android.

Make it ready to enable ipv6 for AIX or HP/UX

Fix missing headers.

Problem: build fails due to undefined INT_MAX

Solution: remove debug printf line completely

Solution: include stdint.h

Solution: include climits

Fixes #1720

truncate rc to INT_MAX for send/recv

to avoid overflow for large messages

send/recv still succeed for large messages,
but `zmq_msg_size` must be used to get the true size.

Last bits of Hurd support

Problem: typo

Solution: fix it

Problem: client over inproc receives the msg with routing id set

Problem: configure --without-documentation is clumsy
