I tried to be smart and skirt around rpf lookup if I knew
the incoming interface. This turns out to be not necessarily
a good thing because we can easily have asymetrical routing.
This fix removes the attempt to cache the ifp we received
the incoming packet on and just lets the lookup work like
it should.
Additionally it removes the weird hardcoding of the rpf
interface from the register stuff.

Just pass in the actual state to allow us to translate
the state to a string even if we don't have a upstream.

When there is allot of IGMP activity for the

ignore it for the moment as well.

Allow the user to specify multiple rp commands.
'ip pim rp A.B.C.D' -> translates to 'ip pim rp A.G.C.D 224.0.0.0/24'
ip pim rp A.B.C.D A.B.C.D/M
First is the rp, second is the group with mask.
Groups and masks cannot be over each other except 224.0.0.0/24 which
is the fallback if used.

Refactor the qpim_rp into pim_rp.c so that the global data
is protected. This will allow us to easily add the group
ranges.

Fix the struct prefix to be an actual struct prefix_sg.
This cleans up a bunch of code to make it look nicer.

When a *,G report is sent, the RPT and WC bits
are set as well as the source is the RP address
for the group.
If this routers idea of the RP for this group is
different than the idea of the RP from the sender
than that particular *,G can be dropped.

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

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.

If a command is put into the VIEW_NODE, it is going into the
ENABLE_NODE as well. This is especially true for show commands.
As such if a command is in both consolidate it down to VIEW_NODE.

The 'struct static_route' data structure duplicated a
decent bit of what is the in the struct channel_oil.
Refactor. This will set us up for further cleanup.

When the kernel sends a NOCACHE message to
pim we were looking up the interface to
use for the incoming multicast packet
based upon the source. No need to do
that trust that the kernel has properly
identified it and use that.

zebra.h pulls in config.h, which results in fiddling with things like
__FILE_OFFSET_BITS. It must always be included first, in order to set
flags that influence the compiler via <features.h>.

(cherry picked from commit 821df2cf18e5978cc7ab532a8695444380d08270)
The linux kernel wants a pimreg vif device. The pimd
code wants a 'struct interface *' for anything it works
with. Since the pimreg vif device is not a real linux
device that zebra knows about. Cheat by creating
a pimreg interface pointer and setup the code to
properly be able to handle the registration of the vif
device.
