    Remove duplicate poller decision making · 48b50cef
    Olaf Mandel authored
    The decision about the poller mechanism to use (select, poll, ...)
    was done twice: once by the build system and once by the code in
    poller.hpp. As the build-system can actually detect the mechanisms
    available, prefer that result to the hard coded defaults in
    poller.hpp.
    
    At the same time, remove the duplicate detection of select() vs.
    poll()-variant from proxy.cpp, signaler.cpp and zmq.cpp.
    
    This patch has not been tested on many build platforms: especially
    the cmake build needs testing / patching. For the other builds,
    hard code the result as these these are all Windows platforms.
