====================
selftests/bpf: Migrate test_tunnel.sh to test_progs

Hi all,

This patch series continues the work to migrate the *.sh tests into
prog_tests framework.

The test_tunnel.sh script has already been partly migrated to
test_progs in prog_tests/test_tunnel.c so I add my work to it.

PATCH 1 & 2 create some helpers to avoid code duplication and ease the
migration in the following patches.
PATCH 3 to 9 migrate the tests of gre, ip6gre, erspan, ip6erspan,
geneve, ip6geneve and ip6tnl tunnels.
PATCH 10 removes test_tunnel.sh
====================

# End-to-end eBPF tunnel test suite
# The script tests BPF network tunnel implementation.
#
# Topology:
# ---------
# root namespace | at_ns0 namespace
# |
# ----------- | -----------
# | tnl dev | | | tnl dev | (overlay network)
# ----------- | -----------
# metadata-mode | native-mode
# with bpf |
# |
# ---------- | ----------
# | veth1 | --------- | veth0 | (underlay network)
# ---------- peer ----------
#
#
# Device Configuration
# --------------------
# Root namespace with metadata-mode tunnel + BPF
# Device names and addresses:
# veth1 IP: 172.16.1.200, IPv6: 00::22 (underlay)
# tunnel dev <type>11, ex: gre11, IPv4: 10.1.1.200, IPv6: 1::22 (overlay)
#
# Namespace at_ns0 with native tunnel
# Device names and addresses:
# veth0 IPv4: 172.16.1.100, IPv6: 00::11 (underlay)
# tunnel dev <type>00, ex: gre00, IPv4: 10.1.1.100, IPv6: 1::11 (overlay)
#
#
# End-to-end ping packet flow
# ---------------------------
# Most of the tests start by namespace creation, device configuration,
# then ping the underlay and overlay network. When doing 'ping 10.1.1.100'
# from root namespace, the following operations happen:
# 1) Route lookup shows 10.1.1.100/24 belongs to tnl dev, fwd to tnl dev.
# 2) Tnl device's egress BPF program is triggered and set the tunnel metadata,
# with remote_ip=172.16.1.100 and others.
# 3) Outer tunnel header is prepended and route the packet to veth1's egress
# 4) veth0's ingress queue receive the tunneled packet at namespace at_ns0
# 5) Tunnel protocol handler, ex: vxlan_rcv, decap the packet
# 6) Forward the packet to the overlay tnl dev
