IP6_TNL_F_ALLOW_LOCAL_REMOTE allows tunnel traffic on ip6tnl devices
where the remote endpoint is a local host address.
Specifying "[no]allow-localremote" controls the
IP6_TNL_F_ALLOW_LOCAL_REMOTE flag on ip6tnl interfaces.
This is the user-space counterpart for kernel
commit 908d140a87a7 ("ip6_tunnel: Allow rcv/xmit even if remote address is a local address")

This is an update for 460c03f3f3 ("iplink: double the buffer size also in
iplink_get()"). After update, we will not need to double the buffer size
every time when VFs number increased.
With call like rtnl_talk(&rth, &req.n, NULL, 0), we can simply remove the
length parameter.
With call like rtnl_talk(&rth, nlh, nlh, sizeof(req), I add a new variable
answer to avoid overwrite data in nlh, because it may has more info after
nlh. also this will avoid nlh buffer not enough issue.
We need to free answer after using.

Take help function in iplink_bridge.c as an example and make other link
types' help functions similar:
* Use a single fprintf() call (if possible).
* Don't state a full command line, just "... type OPTIONS".
* Put every option in it's own line, align options by column.
* List mandatory options first.
link_veth.c is intentionally left untouched because it's 'peer' option
eats all kinds of generic link options and the help text points this out
without duplicating all the options there again.

This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).
Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.
The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.

There is only a single user who needs it to be reentrant (not really,
but it's safer like this), add rt_addr_n2a_r() for it to use.

There have been several instances where response from kernel
has overrun the stack buffer from the caller. Avoid future problems
by passing a size argument.
Also drop the unused peer and group arguments to rtnl_talk.
For some address families (like AF_PACKET) it is helpful to have the
length when prenting the address.

Allow to print particular link type usage by:
ip link help [TYPE]
Currently to print usage for some link type it is needed
to use the following way:
ip link { add | del | set } type TYPE help

This patch allows to manage ip6 tunnels via the interface ip link.
The syntax for parameters is the same that 'ip -6 tunnel'.
It also allows to display tunnels parameters with 'ip -details link' or
'ip -details monitor link'.
