When clagd anycast ip configuration changes on an existing setup, we have two issues:
- populate_dependency_info is run twice (in the ifreload case), first on the new
ifaceobjs, then on the old ifaceobjs. Thus hitting vxlan.get_dependent_ifacenames twice
where vxlan._clagd_vxlan_anycast_ip is set (the first time properly, then reset to it's
old value).
The fix: add a "old_ifaceobjs" flag to avoid resetting vxlan._clagd_vxlan_anycast_ip
- when clagd anycast ip changes, clagd also updates the vxlan's ip but there's a chance
that the ifupdown2 cache won't get the netlink notification in time before UP ops are
running on the vxlans, running on a stale cache is no bueno.
The fix: add additional checks to see if we should trust the cache of not.

Add option 'veth-peer-name' to veth links and ensure proper configuration.
The option »veth-peer-name« forces an veth peer link to be created with
a specific interface name. As the interface name of the "local" part of
the veth link pair already is defined by the name of the interface stanza
this option is added to, now both sides are clearly named.
As there is a bidirectional dependency of both link pairs - both cannot
exist without the other - this presents a problem when setting up all
interfaces. Depending on which interface is set up first there might be
a problem when only on dependency is specified. Therefore adding the
»veth-peer-name« option to both interface of the veth link pair ensures
that regardless of which side is configured first the peer name will be
set correctly. This intentionally creates a circular dependency which is
handled accordingly.
Fixing the config check for veth link-type while at it :)

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
