The kernel already supports it, so add the support
to iproute2 as well.

This patch allows setting VXLAN destination to unicast address.
It allows that VXLAN can be used as peer-to-peer tunnel without
multicast.
v6: change back to the v3 except for using new attribute because
replacing command-line parameters breaks existing scripts,
based by Cong Wang's comments.
v5: rebase on the latest.
v4: replace "group" with "remote" based by David Stevens's comments.
v3: move a new attribute REMOTE into the last of an enum list
based by Stephen Hemminger's comments.
fix the usage to show explicitly that both "remote" and "group"
cannot be specified, based by Ben Hutchings's comments.
v2: use a new argument "remote" instead of "group" based by
Stephen Hemminger's comments.

This change shifts burden onto the users to choose the UDP port value.
Kernel default value is incorrect UDP port 5287 but now there is
an official assigned port for VXLAN.
The kernel can't change because of legacy compatibility
but new deployments should not use the legacy port value.
Add ability to set UDP destination port on a per device basis.
If no port is assigned, the default IANA assigned port will be used.
If you want the kernel default value, then use port 0.
Source port range option is now called 'srcport', to avoid
confusion. The old option syntax is accepted for compatiablity.

This patch improves many error messages as follows:
- For incorrect parameters, show the value of the offending parameter, rather than just say that it is incorrect
- Rephrased messages for clarity
- Rephrased to more `mainstream' english
