For formatting DSCP (not full dsfield), it would be handy to be able to
just get the name from the name table, and not get any of the remaining
cruft related to formatting. Add a new entry point to just fetch the
name table string uninterpreted. Use it from rtnl_dsfield_n2a().

This patch adds support for recently
added link IFLA_PROTO_DOWN_REASON attribute.
IFLA_PROTO_DOWN_REASON enumerates reasons
for the already existing IFLA_PROTO_DOWN link
attribute.
$ cat /etc/iproute2/protodown_reasons.d/r.conf
0 mlag
1 evpn
2 vrrp
3 psecurity
$ ip link set dev vx10 protodown on protodown_reason vrrp on

$ip link set dev vx10 protodown off protodown_reason vrrp off
Error: Cannot clear protodown, active reasons.

Note: for somereason the json and non-json key for protodown
are different (protodown and proto_down). I have kept the
same for protodown reason for consistency (protodown_reason and
proto_down_reason).

Since 'id' is 32bit unsigned, it can never exceed RT_TABLE_MAX (which is
defined to 0xFFFFFFFF). Therefore drop that never matching conditional.

iproute2 can inconsistently show the name of protocol 0 if a route with
a custom protocol is added. For example:
dsa@cartman:~$ ip -6 ro ls table all | egrep 'proto none|proto unspec'
local ::1 dev lo table local proto none metric 0 pref medium
local fe80::225:90ff:fecb:1c18 dev lo table local proto none metric 0 pref medium
local fe80::92e2:baff:fe5c:da5d dev lo table local proto none metric 0 pref medium
protocol 0 is pretty printed as "none". Add a route with a custom protocol:
dsa@cartman:~$ sudo ip -6 ro add 2001:db8:200::1/128 dev eth0 proto 123
And now display has switched from "none" to "unspec":
dsa@cartman:~$ ip -6 ro ls table all | egrep 'proto none|proto unspec'
local ::1 dev lo table local proto unspec metric 0 pref medium
local fe80::225:90ff:fecb:1c18 dev lo table local proto unspec metric 0 pref medium
local fe80::92e2:baff:fe5c:da5d dev lo table local proto unspec metric 0 pref medium
The rt_protos file has the id to name mapping as "unspec" while
rtnl_rtprot_tab[0] has "none". The presence of a custom protocol id
triggers reading the rt_protos file and overwriting the string in
rtnl_rtprot_tab. All of this is logic from 2004 and earlier.
Update rtnl_rtprot_tab to "unspec" to match the enum value.

$ ip li add foobar type vrf table 98765432100123456789
