in less problematic places and finally get
rid of inet_get_addr().

Both ttl/hoplimit is from 1 to 255. Zero has special meaning:
use encapsulated packet value. In ip-link(8) -d output this
looks like "ttl/hoplimit inherit". In JSON we have "int" type
for ttl and therefore values from 0 (inherit) to 255.
To do the best in handling ttl/hoplimit we need to accept
both cases: missing attribute in netlink dump and zero value
for "inherit"ed case. Last one is broken since JSON output
introduction for gre/iptnl versions and was never true for
gre6/ip6tnl.
For all tunnels, except ip6tnl change JSON type from "int" to
"uint" to reflect true nature of the ttl.

There are two reasons for switching to cached variant:
1) ll_index_to_name() may return result from cache,
eliminating expensive ioctl() to the kernel.
Note that most of the code already switched from plain
if_indextoname() to ll_index_to_name() to cached variant
in print path because in most cases cache populated.
2) It always return name in the form "if%d", even if
entry is not in cache and ioctl() fails. This drops
"link_index" from JSON output.

Program type is needed both for parsing and loading of
the program. Parsing may also induce the type based on
signatures from __bpf_prog_meta. Instead of passing
the type around keep it in struct bpf_cfg_in.

ila_csum_name2mode() returning -1 on error but being declared as
returning __u8 doesn't make much sense. Change the code to correctly
detect this issue. Checking for __u8 overruns shouldn't be necessary
though since ila_csum_name2mode() return values are well-defined.

Currently ip6 encap support for lwtunnel is missing.
This patch implement it, mostly duplicating the ipv4 parts.
Also be sure to insert a space after the encap type, when
showing lwtunnel, to avoid the tunnel type and the following
argument being merged into a single word.

Currently parse_encap_ip() does not update correctly argv/argc;
if multiple lwtunnel arguments are provided, the parsing fails after
the first one, i.e.
ip route add 172.16.101.0/24 dev vxlan1 encap ip id 42 dst 192.168.255.1
fails with:
Error: either "to" is duplicate, or "dst" is a garbage.
This commit addresses the issue, stepping to next argument at each iteration
of the parsing loop.

This patch adds support to parse and print lwtunnel
encapsulation attributes attached to routes for MPLS
and IP tunnels.
example:
Add ipv4 route with mpls encap attributes:
Examples:
MPLS:
$ ip route add 40.1.2.0/30 encap mpls 200 via inet 40.1.1.1 dev eth3
$ ip route show
40.1.2.0/30 encap mpls 200 via 40.1.1.1 dev eth3
Add ipv4 multipath route with mpls encap attributes:
$ ip route add 10.1.1.0/30 nexthop encap mpls 200 via 10.1.1.1 dev eth0 \
nexthop encap mpls 700 via 40.1.1.2 dev eth3
$ ip route show
10.1.1.0/30
nexthop encap mpls 200 via 10.1.1.1 dev eth0 weight 1
nexthop encap mpls 700 via 40.1.1.2 dev eth3 weight 1
IP:
$ ip route add 10.1.1.1/24 encap ip id 200 dst 20.1.1.1 dev vxlan0
