- The 'reject' keyword was being lost
- Hide the "ip route A.B.C.D A.B.C.D" config options since these will be
displayed as "ip route A.B.C.D/X"
Also:
- Add documentation on mailing list
- Update mentions of unit tests
- Update process description

The NHT upstream list at scale is horribly inefficient due to keeping
a sorted list of upstream entries. The attempting to find
the upstream and the insertion of it into the upstream_list
was consuming a large amount of cpu cycles.
Convert to a hash, allow add/deletions to effectively become
O(1) events.

Fixes#407 for FreeBSD and NetBSD.
OpenBSD uses ioctl to fetch interface information on startup and the
SIOCGIFMEDIA command is just too cumbersome to use.
The best way to fix the problem for OpenBSD is probably to stop treating
it differently from the other BSDs for no apparent reason. There should
be nothing preventing us to make OpenBSD use the routing socket to fetch
interface information on startup (we already do it to detect runtime
changes). This is something that should be done in a separate commit
after a careful analysis.

We were assuming that a neighbor can be deleted only when all of its
adjacencies are dead. This is not the case for dual-stack neighbors. If
the transport-preference is IPv4 and all adjacencies are IPv6 (or
vice-versa), then it should be deleted and everything cleaned-up
accordingly.
Bug exposed by the new RB tree implementation on master, but the fix
also applies to stable/3.0.

Commit 8f942af90 introduced a bug while silencing a clang warning. Silence
the warning in a different way to fix our red-black tree implementation.
Fixes#841.

We should preserve the original indentation to make it easier to keep
these files in sync with the upstream.

When we receive a new ecmp path and the old nexthop is still
valid. There existed some cases where we would continue looking
for a nexthop( and thus loose the fact that we had found it )

During normal course of operations, zebra sends the ZEBRA_INTERFACE_VRF_UPDATE
call up into all connected zclients. In the case of PIM the
zlookup was expecting a min length of 10, but ZEBRA_INTERFACE_VRF_UPDATE
was sending of size 6. This min length check makes no sense,
so just remove.

When we receive a SGRPT Prune we were switching the upstream
to JOINED and immediately sending a join. This was not
the right thing to do.
This was happening because we were making decisions about the
new ifchannel before it was fully formed.
Rework ifchannel startup to provide enough information to
the pim upstream data structure to make the right decisions

When we receive a register message for an existing S,G
and the SPT bit is not set, then do a quick check against
the S,G to see if we have counters updated. This is added
because the existing S,G wheel_timer only updates every
31 seconds and it is possible for a Null Register to
have come in before that first 30 second timer pops.
