The example script touches the stable-id of a connection.
It does so blocking autoconnect, and was originally written
to test that functionality.

Show how to load and use the VPN plugins from python.

Converted from python/gi/get_ip.py.

On modern distributions, ld runs with the '--as-needed' option
enabled by default, meaning library dependencies must come after
files that require them. Also, this allows indirect linking so the
build commands can be simplified.

The alternative is to add the '-Wl,--no-as-needed' gcc option or
use the top-level Makefile.

Tested on:
 * Ubuntu 16.04.3 with gcc Ubuntu 5.4.1-8ubuntu1
 * Fedora 24 with gcc Red Hat 6.1.1-3

Add an example python script to show and set setting's
user-data. This is useful, as nmcli still doesn't support
user data.

Changing the MAC address of devices is known to fail with
certain drivers. Add a device-spec to allow disabling it
for for such devices.

In practice, this should only matter when there are multiple
header files with the same name. That is something we try
to avoid already, by giving headers a distinct name.

When building NetworkManager itself, we clearly want to use
double-quotes for including our own headers.
But we also want to do that in our public headers. For example:

  ./a.c
    #include <stdio.h>
    #include <nm-1.h>
    void main() {
        printf ("INCLUDED %s/nm-2.h\n", SYMB);
    }

  ./1/nm-1.h
    #include <nm-2.h>

  ./1/nm-2.h
    #define SYMB "1"

  ./2/nm-2.h
    #define SYMB "2"

$ cc -I./2 -I./1 ./a.c
$ ./a.out
INCLUDED 2/nm-2.h

Exceptions to this are
  - headers in "shared/nm-utils" that include <NetworkManager.h>. These
    headers are copied into projects and hence used like headers owned by
    those projects.
