Problem: including recent "zmq_utils.h" crashes gcc -pedantic jobs

Browse Source 
Problem: Recent deprecation of the "zmq_utils.h" header file caused pedantic compilations (including czmq) to fail because non-portable #warning is used.
Solution: Limit the deprecation warnings to compilers known or assumed to support the "#pragma message" (GCC, MSVC, CLANG) and wrap with GCC directives to not treat these warnings as errors on paranoid builds.

/* This file is deprecated, and all its functionality provided by zmq.h */
/* Note that -Wpedantic compilation requires GCC to avoid using its custom
extensions such as #warning, hence the trick below. Also, pragmas for
warnings or other messages are not standard, not portable, and not all
compilers even have an equivalent concept.
So in the worst case, this include file is treated as silently empty. */
