REVISION SUMMARY
  AbstractClient gains a new pure virtual killWindow method and this gets
  implemented in ShellClient.
  
  ShellClient performs the killing by sending a term signal to the
  process. This can only work if the client connected through the socket
  and didn't get a socketpair fd passed. In that case the pid is KWin's
  and KWin doesn't want to terminate. Thus this is special handled to
  destroy the connection instead.
  
  In case terminating the process has no effect, the connection gets
  destroyed after five seconds.
  
  The KillWindow is adjusted to operate on AbstractClient instead of
  Client.
  
  This implements https://phabricator.kde.org/T4463.
