Recent additions to prefix_copy to check afi type exposed

This allows frr-reload.py (or anything else that scripts via vtysh)

Instead of having an ?: expression embedded in every single caller of
vty_out, just expand \n to \r\n in the vty code if neccessary.
(Deprecation warnings will be enabled in the next commits which will do
the search-and-replace over the codebase.)

Most of the attributes in 'struct attr_extra' allow for
the more interesting cases of using bgp. The extra
overhead of managing it will induce errors as we add
more attributes and the extra memory overhead is
negligible on anything but full bgp feeds.
Additionally this greatly simplifies the code for
the handling of data.

Test cases create fake bgp structure that is passed to
cleanup. The new evpn code assumed ( and probably rightly so)
that if the bgp structure was created it actually initialized
all useful data structures. Just make the evpn cleanup
functions be smart about attempting to free memory never
allocated.

Implement support for sticky (static) MACs. This includes the following:
- Recognize MAC is static (using NUD_NOARP flag) and inform BGP
- Construct MAC mobility extended community for sticky MACs as per
RFC 7432 section 15.2
- Inform to zebra that remote MAC is sticky, where appropriate
- Install sticky MACs into the kernel with the right flag
- Appropriate handling in route selection

Core EVPN route handling functionality. This includes support for the
following:
- interface with zebra to learn about local VNIs and MACIPs as well as
to install remote VTEPs (per VNI) and remote MACIPs
- create/update/delete EVPN type-2 and type-3 routes
- attribute creation, route selection and install
- route handling per VNI and for the global routing table
- parsing of received EVPN routes and handling by route type
- encoding attributes for EVPN routes and EVPN prefix creation (for
