Add options for group-list and source-list, both of which take a prefix list name.
The prefix list is used to determine the lookup mode for specific sources and/or groups.
Any number of lookup modes can be configured as long as the combination of group
and source list is unique.
A global lookup mode (empty group and source lists) is always added and defaults to mrib-then-urib
as it currently functions. The global lookup mode can be changed as it current exists with the command
`rpf-lookup-mode MODE`.
When determinig which mode to use, match source (and group if provided) against the lists, if they are set.
If a lookup does not specify a group, then only use lookup modes that do not have a group list defined.
A lookup by definition will have a source, so no special handling there.

Refactor the next hop tracking in PIM to fully support the configured RPF lookup mode.

pimd: MSDP per peer SA limit

Add new interface command ip multicast boundary ACCESSLIST4_NAME. This
allows filtering on both source and group using the extended access-list
syntax vs. group-only as with the existing "ip multicast boundary oil"
command, which uses prefix-lists. If both are configured, the prefix-
list is evaluated first. The default behavior for both prefix-lists and
access-lists remains "deny", so the prefix-list must have a terminating
"permit" statement in order to also evaluate against the access-list.
The following example denies groups in range 229.1.1.0/24 and groups in
range 232.1.1.0/24 with source 10.0.20.2:
!
ip prefix-list pim-oil-plist seq 10 deny 229.1.1.0/24
ip prefix-list pim-oil-plist seq 20 permit any
!
access-list pim-acl seq 10 deny ip host 10.0.20.2 232.1.1.0 0.0.0.255
access-list pim-acl seq 20 permit ip any any
!
interface r1-eth0
ip address 10.0.20.1/24
ip igmp
ip pim
ip multicast boundary oil pim-oil-plist
ip multicast boundary pim-acl

New CLI commands added:
router pim [vrf NAME]
autorp discovery
autorp announce RP-ADDR [GROUP | group-list PREFIX-LIST]
autorp announce {scope (1-255) | interval (1-65535) | holdtime (0-65535)}
autorp discovery
Enables Auto RP discovery for learning dynamic RP information using the
AutoRP protocol.
autorp announce RP-ADDR [GROUP | group-list PREFIX-LIST]
Enable announcements of a candidate RP with the given group range, or
prefix list of group ranges, to an AutoRP mapping agent.
autorp announce {scope (1-255) | interval (1-65535) | holdtime (0-65535)}
Configure the parameters of the AutoRP announcement messages.
The scope sets the packet TTL.
The interval sets the time between TX of announcements.
The holdtime sets the hold time in the message, the time the mapping
agent should wait before invalidating the candidate RP information.
debug pim autorp
Enable debug logging of the AutoRP protocol
show ip pim [vrf NAME] autorp [json]
Show details of the AutoRP protocol.
To view learned RP info, use the existing command 'show ip pim rp-info'
Extend pim yang for new configuration:
augment /frr-rt:routing/frr-rt:control-plane-protocols/frr-rt:control-plane-protocol/frr-pim:pim/frr-pim:address-family:

PIM: Implement static IGMP joins without an IGMP report
|
|
This will add a static IGMP group that does not rely on an underlying
socket join which sends traffic to the cpu unneccesarily. Instead, the
groups are joined directly without any IGMP interactions.
New command is under interfaces, 'ip igmp static-group ...'.
Added an alias for 'ip igmp join ...' to 'ip igmp join-group'.
Moved IGMP join groups to new yang list "join-group" and reused
the "static-group" list for the IGMP static groups.

Implement MSDP MD5 authentication connection support.
Implementation details:
- Move the MSDP socket creation code to a generic function so it can be
parametrized to be used with/without authentication.
- The MSDP peer connection will not change when the configuration is
set, instead it will only be applied next connection or when
`clear ip msdp peer A.B.C.D` is called.

The YANG specification currently designates a uint8 data type for the hello interval,
despite the CLI documentation (ip pim hello (1-65535) [(1-65535)]) indicating a maximum value of 65535.
To address this inconsistency, updating the data type to uint16 allowing for a maximum value for hello intervals.

config apply
Currently, in PIM Northbound, when a path to RP is not found during config apply, we are treating this as a NB_ERR_INCONSISTENCY.
However, there are two issues with this approach:
When OSPF or IGP convergence is completed, it is possible that the RPF check will succeed.
If we have multiple groups and RPs (e.g. 50 RPs), we will receive 50 logs with inconsistency errors.
example:
2023/05/27 22:57:45 PIM: [G822R-SBMNH] config-from-file# ip pim rp 192.168.100.1 239.100.0.0/28 2023/05/27 22:57:45

Problem:
Execute the below commands, pim6d core happens.
interface ens193
ip address 69.0.0.2/24
ipv6 address 8000::1/120
ipv6 mld
ipv6 pim
We see crash only if the interface is not configured, and
we are executing PIM/MLD commands.
RootCause:
Interface ens193 is not configured. So, it will have
ifindex = 0 and mroute_vif_index = -1.
Currently, we don't enable MLD on an interface if
mroute_vif_index < 0. So, pim_ifp->MLD = NULL.
In the API pim_if_membership_refresh(), we are accessing
pim_ifp->MLD NULL pointer which leads to crash.
Fix:
Added NULL check before accessing pim_ifp->MLD pointer in
the API pim_if_membership_refresh().

pim6d: Implementing "ipv6 mld join"

After doing "no ipv6 pim" and "ipv6 pim" on receiver interface in LHR,
mroutes were not created.
When we enable pim after disabling it, we refresh the membership on pim interface.
First we clear the membership on the interface, then we add it back.
For PIMv6 we were only clearing it, membership was not added back. So mroutes were not created.
Now added code to fetch all the local membership information into PIM.

Pim upstream IIF is still pointing towards the source connected
interface which is not pim enabled and not IGMP enabled and
Mroute is still present in the kernel and KAT timer is still running
on the interface, where ifp->info is already set to NULL.
This leads to crash.
Root Cause:
==========
When "no ip pim" commands get executed on source connected interface,
we are updating upstream IIF only when IGMP is not enabled on the same
interface.
Fix:
===
When PIM is disabled on source connected interface, update upstream IIF
no matter if IGMP is enabled or not on the same interface.

Problem:
When "no ip pim" is executed on source connected interface, its
ifp->info is set to NULL. But KAT on this interface is still
running, it wrongly dereferences NULL. This leads to crash.
Root Cause:
pim upstream IIF is still pointing towards the source connected
interface which is not pim enabled and Mroute is still present in
the kernel.
Fix:
When “no ip pim” command gets executed on source connected interface,
then loop through all the pnc->nexthop, if any new nexthop found,
then update the upstream IIF accordindly, if not found then update
the upstream IIF as Unknown and uninstall the mroute from kernel.
When “ip pim” command gets executed on source connected interface,
then also loop through all the pnc->nexthop and update the upstream IIF,
install the mroute in kernel.
