    Bug 18821: Disable libmdns for Android and Desktop
    
    There should be no need to remove the OS X support introduced in
    https://bugzilla.mozilla.org/show_bug.cgi?id=1225726 as enabling this
    is governed by a preference (which is actually set to `false`). However,
    we remove it at build time as well (defense in depth).
    
    This is basically a backout of the relevant passages of
    https://hg.mozilla.org/mozilla-central/rev/6bfb430de85d,
    https://hg.mozilla.org/mozilla-central/rev/609b337bf7ab and
    https://hg.mozilla.org/mozilla-central/rev/8e092ec5fbbd.
    
    Fixed bug 21861 (Disable additional mDNS code to avoid proxy bypasses)
    as well.
