Merge remote-tracking branch 'remotes/gkurz/tags/for-upstream' into staging

- fixes a minor bug that could possibly prevent old guests to remove
  directories
- makes default permissions for new files configurable from the cmdline
  when using mapped security modes
- handle transport errors
- g_malloc()+memcpy() converted to g_memdup()
