Convert ifchannel to use a prefix to store (s,g) information.
Additionally create pim_str_sg_dump function to output
data when using debugs.

pim was sending the join from the RP towards the FHR with
a address that was the source instead of the nexthop. This join
was treated as a non-local and nothing was done with it.

Implement the pim_register_stop state machine. There are still a few
bugs still but this is enough to get us rolling a bit more.

When sending a pim register message to an RP, we need
the ability to set the null bit in the message. This
adds the ability to do so.
Additionally we need to switch the ip_hdr to a const uint8_t *buf
because pim_register_send really shouldn't know or care about
the fact it's a 'struct ip'.

We were using a variety of techniques to handle
incoming pim packets. Refactor to use a switch
statement to handle the incoming packets.
Also add the ability to notice that we are getting
a register stop.

The RP now has the ability to send a register stop message
to the originator of the packet in order to tell it to
stop encapsulating packets to the RP.

This moves all install_element calls into the file where the DEFUNs are
located. This fixes several small related bugs:
- ospf6d wasn't installing a "no interface FOO" command
- zebra had a useless copy of "interface FOO"
- pimd's copy of "interface FOO" was not setting qobj_index, which means
"description LINE" commands would fail with an error
The next commit will do the actual act of making "foo_cmd" static.

When displaying drpriority you can enter unsigned
integer values from 1-2^32. The display was
turning the unsigned value into a signed value
and thus we were displaying the wrong value.

Linux, FreeBSD and NetBSD (and possibly others too) accept both uint8_t
and int for the IP_MULTICAST_LOOP sockoption. OpenBSD, in the other hand,
accepts only uint8_t. To make setting IP_MULTICAST_LOOP work on every
supported platform, always pass a uint8_t variable as a parameter.

Since we have autoconf results from a wide swath of target platforms, we
can go remove checks that have the same result on all systems.
This also removes several "fallback" implementations of functions that,
at some point in the history, weren't available on all target platforms.

If a command is put into the VIEW_NODE, it is going into the

As such if a command is in both consolidate it down to VIEW_NODE.

This patch improves zebra,ripd,ripngd,ospfd and bgpd so that they can
make use of 32-bit route tags in the case of zebra,ospf,bgp or 16-bit
route-tags in the case of ripd,ripngd.
It is based on the following patch:
