fixes two issues via patches to get knetwork compiling

kopete-4.10.4-kopete-linphonemediaengine.patch
----------------------------------------------
patch copied from here:
  https://bugs.kde.org/show_bug.cgi?id=318825

kopete-4.10.4-kopete-stun.patch
-------------------------------
  when compiling kopete/protocols/jabber/googletalk/libjingle/talk/session/phone/channelmanager.cc
  it would produce this error:

  kopete/protocols/jabber/googletalk/libjingle/talk/p2p/base/stunrequest.h:91:9: error: ‘StunMessageType’ does not name a type

  problem:
    this is cased by a cyclic use of stun.h, stunrequest.h and channelmanager.cc with the outcome,
    that kdenetwork couldn't be compiled since kopete fails to build.

  solution:
    move the StunMessageType enum into its own #ifndef
