433d9566bf doc: add FRR/Linux configuration examples for EVPN 
The existing EVPN documentation in bgp.rst does not provide a holistic
configuration, just examples of individual features, and doesn't give
an operator any idea of what a compatible Linux netdev configuration
might look like. This introduces evpn.rst which includes a sample
frr.conf and corresponding Linux interface config (via iproute2) that
an operator can use to setup a basic EVPN topology and model their
interface manager's config from.

This initial version of evpn.rst shows Linux netdev config for
traditional bridges (vlan_filtering=0) and traditional vxlan devices
(single VNI). Later changes to this file will cover the use of
VLAN-aware bridges (vlan_filtering=1), single VXLAN devices
(multi VNI), and eventually bonds (for EVPN-MH).

Eventually the plan is to move the existing EVPN content from bgp.rst
into evpn.rst, but for now let's get some user-facing documentation in
place for interface configs.

Two "example" (but real) accords are included, mostly to illustrate the
idea.  Both of these should be non-controversial and have had some
previous discussion in random places.

bgp->name as NULL.  This of course crashes the ilk

so that it doesn't crash.

Increase the MSDP peer stream buffer size to handle the whole TLV
(maximum is 65KiB due to 16bit field). If the stream is not resized
there will be a crash in the read function attempting to put more than
9192 (`PIM_MSDP_SA_TLV_MAX_SIZE`) bytes.

According to the RFC 3618 Section 12 we should accept the TLV and we
should not reset the peer connection.
