    build: merge branch 'th/clang-build-fixes'
    
    Update m4/compiler_warnings.m4 with what we have on NetworkManager
    master. With this I can build nm-applet on Fedora 21 with clang.
    
    Also fix two bugs that were found by clang warnings.
    
    (cherry picked from commit c531937f8c37dc38e1a88105704d40f5cb64b6ed)
