ifupdown2 behaviour significantly diverges from ifupdown on debian stretch.
Original ifupdown uses run-parts which supposedly doesn't run non-executable
files in the directory. However, ifupdown2 doesn't seem to make this
distinction.
This patch will log warning EACCES exceptions (instead of log error) and exit 0

ifupdown2 used /var/tmp/network/ to store its state file
upstream users reported that when /var/tmp is not mounted
before network configuration ifupdown2 fails. We now let
user define which location they want to use for the state
file.

The new code base supports installation via pypi so we need to update the
imports statement.
It's also good practice to use the existing IO apis to read/write and execute
sub-commands, those API will do error handling and logging.

batman wasn't in master-next so it got removed during the last merge
this commit adds it back to master.
See PR #12
From Maximilian Wilhelm:
This commit adds support for configuring B.A.T.M.A.N. advanced interfaces
with ifupdown2. B.A.T.M.A.N. advanced is a protocol to build Layer2 based
mesh networks with. It's supported in the Linux kernel and thus available
in many Linux environments.
A configuration could look like this
auto bat0
iface bat0
batman-ifaces eth1 eth2.23
batman-ifaces-ignore-regex .*_nodes
batman-hop-penalty 23
#
address 192.0.2.42/24
where »bat0« would be the local connection to the mesh network.
The interfaces »eth1« and »eth2.23« would be used by the B.A.T.M.A.N. adv.
protocol to communicate to other member of the mesh network.
Any interfaces matching the »ifaces-ignore-regex« will be gently ignored
by ifquery and ifreload as there might be some tunnels or interfaces
added to the mesh network by other means which should not be removed by
any subsequent ifreload run.
The »hop-penalty» parameter set the penalty of this node within the mesh
network.

During the recent merge between master and master-next the changes introduced
by PR #80 were lost. This commit adds them back with some refactoring to use
the new netlink cache.

ifupdown2 can be installed via apt/dpkg or via pypi (pip), those two installation methods have
two different installation directory. Our main installation dir is /usr/share/ifupdown2. This is
also were other scripts might add their own addon.
If ifupdown2 is installed via pypi we need to make sure we are loading the script-added addon modules

-n sets DRYRUN flags, when DRYRUN is set many functions return True
(like link_exists), in this case vxlanattrs is set to False because
not cached. But since link_exists=True we still try to access it like
a dictionary.

The issue here lies with how we query the cache to get the ips addresses
configured on the macvlan. A few months ago we added support for link scope
addresses in the cache, since the kernel may add it's own link addresse to
some interfaces we need to filter them out when querying the cache (because
we just want to get the list of IPs managed by ifupdown2). To perform this
filtering we need to look at the current user configuration (/e/n/i) but we
also need to look at past configuration. To perform this filtering we need
to provide the API LinkUtils:get_running_addrs a special parameter for
address-virtual (we need an ifaceobj).

mstpctl might return an empty result on: mstpctl showportdetail bridge json
the cache is not filled with an empty dict so next cache lookup will be a
cache miss and therefore, ifupdown2 thinks we need to fill the cache with fresh
data and will execute showportdetail again (resulting in calling mstpctl cmd
sometime 5 or 6 times in a row).
