ethernet: Fix ethtool not_supported handling
util: introduce new intmap file parser
schema,mkconst: make route table a string

Factor in use of intmap file parser to pull custom route table names
from /etc/iproute2/rt_tables.

To address bnc#885007
route: shift to new route table apis
leasinfo: shift to new route table apis
client: shift to new route table apis
iflist: shift to new route table apis
dbus: shift to new route table apis and process route table as string per schema

Merge pull request #426 from kmroz/bnc885007-2-rc2

routes: lookup and accept custom table names (bnc#885007)
Merge pull request #429 from kmroz/fix-iflist

iflist: set route table from netlink if available
icmpv6: utility to send icmpv6 router solicitation
ipv6: maintain lifetime for rdnss servers separately
lease: enabled save/load of auto and intrinsic leases
leaseinfo: qualify ipv6 link-local dns server addrs

Also added type family and uuid to the lease info.
ifconfig: apply address lease priorities same as for routes

This effectively allows dhcp6 to takeover addresses guessed
auto6, e.g. after restart and lifetime updates on renewal.
