Subject: [PATCH] Avoid deprecated bind placeholders in global namespace

This fixes numerous compilation warnings:

  note: #pragma message:
    The practice of declaring the Bind placeholders (_1, _2, ...)
    in the global namespace is deprecated.
    Please use <boost/bind/bind.hpp> + using namespace boost::placeholders,
    or define BOOST_BIND_GLOBAL_PLACEHOLDERS to retain the current behavior.
