Travis includes gnutls in the default package set, but it is
an outdated version linkng to an incompatible libffi version.
The 'update: true' stanza causes the brew toolchain to be
updated but not the installed formula. It is possible to
run 'brew upgrade' to update installed formula, but this is
very slow adding more than 5 minutes to the build time.
Listing the gnutls package explicitly causes it to be updated
without extending the build time.

Commit 21ad56e9 introduced a regression where a VM with a corrupted

caused by returning a wrong return code as 'fd' was abused to also hold

Since it's easy to miss this nuance, introduce a 'ret' variable for the
return code and return it' value in the error section.

When a device is "move"-d (this basically means it was renamed),
we add the new device onto our list but keep the old there too.
Fortunately, udev sets this DEVPATH_OLD property which points to
the old device path. We can use it to remove the old instance.

To test this try renaming an interface, for instance:

  # ip link set tunl0 name tunl1
  # ip link set tunl1 name tunl0

One problem with udev is that it sends old ifname in INTERFACE
property, which creates a problem for us, the property is where
we get the ifname from and use it then to query all kind of info
about the interface. Well, if it is non-existent then we can't
query anything. This happens if ifname rename is suppressed
(net.ifnames=0 on kernel cmd line for instance). Fortunately, we
can use "kernel" source for udev events which has always the
fresh info.
