There exist systems that do not explicity have a python soft-link
on their system. Let's explicity call out which python we want
to be using with exabgp.

For IPv4 matching, we have "match ip next-hop address A.B.C.D".
For IPv6 matching, we have "match ipv6 next-hop X:X::X:X".
To have consistency, let's add "address" keyword to IPv6 commands.
Old commands are preserved as hidden for backward compatibility.

Problem Statement:
==================
on rp_change, PIM processes all the upstream in a loop and for selected
upstreams PIM has to send join/prune based on the RPF changed.
join and prune packets are not getting aggregated in a single packet.
Root Cause Analysis:
====================
on pim_rp_change pim_upstream_update() gets called for selected upstreams.
This API calculates to whom it has to send join and to whom it has to
send prune via API pim_zebra_upstream_rpf_changed(). This API peprares
the upstream_switch_list list per interface and inserts the group and
sources.
Now PIM is still in the pim_upstream_update() API context, i.e PIM
is still processing the same upstream. In the last there is a
call to pim_zebra_update_all_interfaces() which processes the
upstream_switch_list list, sends the packets out and clears the list.
Fix:
====
Don't process the upstream_switch_list in the upstream context.
process all the upstreams prepare the upstream_switch_list and then
process in one go. This will club all the S,G entries.
It also saves list cleanup with respect to memory allocation and
deallocation multiple times.

the fix consists in parsing the ext community list ipv6 by taking
account the size of the ecommunity val size.

During zebra shutdown, we clear out the LSP workqueue. The LSPs
will be uninstalled and freed during the shutdown process, so
just ignore any LSPs that happen to be on the workqueue.

to be a cocci script.)

failed when the caller did not pass in a valid

a pointer not being passed in and remove the
bool return

The only time this function ever failed is when
the developer does not pass in a usable pointer
to place the data in. Change it to an assert
to signify to the end developer that is what
we want and then remove all the if checks
for failure

The function call dplane_ctx_get_pbr_ipset only
returns false when the calling function fails to
pass in a valid ipset pointer. This should
be an assertion issue since it's a programming
issue as opposed to an actual run time issue.
Change the function call parameter to not return
a bool on success/fail for a compile time decision.
