There is a possibility that the same line can be matched as a command in
some node and its parent node. In this case, when reading the config,
this line is always executed as a command of the child node.
For example, with the following config:
```
router ospf
network 193.168.0.0/16 area 0
!
mpls ldp
discovery hello interval 111
!
```
Line `mpls ldp` is processed as command `mpls ldp-sync` inside the
`router ospf` node. This leads to a complete loss of `mpls ldp` node
configuration.
To eliminate this issue and all possible similar issues, let's print an
explicit "exit" at the end of every node config.
This commit also changes indentation for a couple of existing exit
commands so that all existing commands are on the same level as their
corresponding node-entering commands.
Fixes#9206.

VRF creation can happen from either cli or from
knowledged about the vrf learned from zebra.
In the case where we learn about the vrf from
the cli, the vrf id is UNKNOWN. Upon actual
creation of the vrf, lib/vrf.c touches up the vrf_id
and calls pim_vrf_enable to turn it on properly.
At this point in time we have a pim->vrf_id of
UNKNOWN and the vrf->vrf_id of the right value.
There is no point in duplicating this data. So just
remove all pim->vrf_id and use the vrf->vrf_id instead
since we keep a copy of the pim->vrf pointer.
This will remove some crashes where we expect the
pim->vrf_id to be usable and it's not.

Problem reported that when certain pim commands were entered, they
showed up duplicated in the configuration both under default instance
and every vrf (whether pim was used there or not.) This was because
these particular parameters are global only and the function doing
the display would repeat for each vrf. This fix only displays those
in the default case (and removes them from the help for entering
under a vrf.)

Replace sprintf with snprintf where straightforward to do so.
- sprintf's into local scope buffers of known size are replaced with the
equivalent snprintf call
- snprintf's into local scope buffers of known size that use the buffer
size expression now use sizeof(buffer)
- sprintf(buf + strlen(buf), ...) replaced with snprintf() into temp

This CLI will allow user to configure a igmp group limit which will generate
a watermark warning when reached.
Though watermark may not make sense without setting a limit, this
implementation shall serve as a base to implementing limit in future and helps
tracking a particular scale currently.
Testing:
=======
ip igmp watermark-warn <10-60000>
on reaching the configured number of group, pim will issue warning

1. Upstream entries associated with tunnel termination mroutes are
synced to the MLAG peer via the local MLAG daemon.
2. These entries are installed in the peer switch (via an upstream
ref flag).
3. DF (Designated Forwarder) election is run per-upstream entry by both
the MLAG switches -
a. The switch with the lowest RPF cost is the DF winner
b. If both switches have the same RPF cost the MLAG role is
used as a tie breaker with the MLAG primary becoming the DF
winner.
4. The DF winner terminates the multicast traffic by adding the tunnel
termination device to the OIL. The non-DF suppresses the termination
device from the OIL.
Note: Before the PIM-MLAG interface was available hidden config was
used to test the EVPN-PIM functionality with MLAG. I have removed the
code to persist that config to avoid confusion. The hidden commands are
still available.

Original Idea is to display normal & detailed debugs when detailed
debug alone is configured. because of this "sh debugs" are showing
wrong Information, because same macro is used to disply the configured
debugs.
that means even if Normal debug is configured, detailed macro returns
TRUE. To avoid this ambiguity check whetehr detailed debug is configured
or not during dumping configured debugs. In all other places using
old macro.

The definition of the interface commands in vtysh.c were outdated.
Currently, all daemons that call if_cmd_init() will have the "no interface
IFNAME" command and the "[no] description" commands as well, so there's
no need to define exceptions for these commands anymore.
To fix this, make extract.pl parse the if.c file so that vtysh can get the
interface commands from there automatically. Only the "interface IFNAME
[vrf NAME]" must be kept in vtysh.c because it changes the vty node and
thus needs special treatment.
Finally, make pimd and pbrd display interface descriptions on "sh run"
when they are configured.
