some of those release were available but under a different name so
technically those version numbers were never released.

As shown in the following example, ifupdown1 sets the default route with the
onlink attribute. This patch will add this capability to ifupdown2 controlled
by a policy variable in the address module: "l3_intf_default_gateway_set_onlink"
default to on

Ifupdown2 is now setting a default metric on macvlan ips. This policy will let
users disable this new default behavior. addressvirtual_with_route_metric is
boolean policy variable.
addressvirtual_with_route_metric: yes|no|on|off|1|0 (default to yes)
$ cat /var/lib/ifupdown2/policy.d/addressvirtual.json

closes#58
In linux its possible to assign a vlan-aware bridge an ip address
For some use cases is it useful to restrict users from configuring
ips on bridges VA. This patch will let admins and distributions
decide if it is necessary to warn the user in such case.

This is a major update coming all at once from master-next branch
master-next branch was started with --orphan option which is basically a new
branch without history.
The major changes are:
- repackaging
- cleanup the directory tree
- rewritte setup.py to allow install from deb file or pypi (pip install)
- add a Makefile to make things (like building a deb) easier
- review all debian files

Reviewed By: Roopa, Kanna, Scott E
Testing Done:
This patch also fixes a problem where dhcp6 used to create lease file with
a trailing whitespace. dhcp6 operation were also sometimes using the wrong
pid file. I added some code in the debian.postinst script to correctly
rename these files if they exists when we install/update ifupdown2.
