[PATCHv4 iproute2-next 0/7] iproute2: fully support for geneve/vxlan/erspan options

[Xin Long <lucien.xin@gmail.com>]

Patch 1-3 add the geneve/vxlan/erspan options support for
iproute_lwtunnel, and Patch 4-5 add the vxlan/erspan options
for tc m_tunnel_key, and Patch 6-7 add the vxlan/erspan options
for tc f_flower.

In kernel space, these features have been supported since these
patchsets:

v1->v2:
  - improve the bash commands in changelog as David A. suggested.
  - use PRINT_ANY to support dummping with json format as Stephen
    suggested.
v2->v3:
  - implement proper JSON array for opts as Stephen suggested.
v3->v4:
  - Basically we print all options as uint, other than 'data' in
    the 1st patch as a hex string.
  - As Stephen's suggestion, we keep all those options of the same
    format between input and output, and between json and non json.
