This change will stop this action from running on forked repos.
Previously whenever one pushed a change to one's development branch the
action would "run but skip" which still generated an email notifications
and thus was very annoying. :)

When the kernel is not compiled with mroute vrf's enabled it will
fail the call to initialize the vrf. As such let's recognize this
specific error code and output a specific warning to the operator

Before we checked for received Graceful Restart capability, but that was also
incorrect, because we SHOULD HAVE checked it per AFI/SAFI instead.
https://datatracker.ietf.org/doc/html/rfc4724 says:
Although the End-of-RIB marker is specified for the purpose of BGP
graceful restart, it is noted that the generation of such a marker
upon completion of the initial update would be useful for routing
convergence in general, and thus the practice is recommended.
Thus, it might be reasonable to send EoR regardless of whether the Graceful Restart
capability is received or not from the peer.

lib/typesafe.h was supposed to be outside the _TYPESAFE_EXPAND_MACROS
guard, so that including lib/atomlist.h grabs all the typesafe container
macros.
(No effect on normal build, as _TYPESAFE_EXPAND_MACROS is never defined
there.)

There is no reason to call `igmp_anysource_forward_stop()` inside a call to
`igmp_get_source_by_addr()`; not only it is not expected for a "get" function
to perform such an action, but also the decision to start/stop forwarding is
already handled correctly by pim outside `igmp_get_source_by_addr()`.
That call was left there from the days pim was initially imported into the sources.
The problem/crash was happening because `igmp_find_source_by_addr()` would fail to
find the group/source combo when mixing `(*, G)` and `(S, G)`. When having an existing
flow `(*, G)`, and a new `(S, G)` igmp is received, a new entry is correctly created.
`igmp_anysource_forward_stop(group)` always stops and eventually frees `(*, G)`, even
when the new igmp is `(S, G)`, leaving a bad state. I.e, the new entry for `(S, G)`
causes `(*, G)` to be deleted.
Tested the fix with multiple receivers on the same interface with several ssm and
any source senders and receivers with various combination of start/stop orders and
they all worked correctly.

Contains 2 testcases. The first does a basic configuration/connectivity.
The second testcase initiates a shortcut through the primary NHS,
verifies shortcut routes are installed. Primary NHS interface brought
down and verify that the shortcut is not impacted. Finally verify that
after the shortcut expires, it is able to be re-established via a backup
NHS.

Locally this test would occassionally fail for me
because the connected route the sharp route being

Using absolute xpath is not optimal for finding the target node. As the
route map configuration grows, the yang validation will take more time
to complete. Relative paths are much faster.
Tested with a config file that contains ~3k route map config lines.

When a router route already exists in the area border routers table
as an ABR and it solely changes its ABR or ASBR status, the change
was missed and border route is not updated. This fixes the comparison
for the router_bits in the ospf6_path structure.
This fixes issue https://github.com/FRRouting/frr/issues/16053 although
the actual problem is not the computing router (r2) and not the OSPFv3
redistribution (r3).

1. When the command "no <ip|ipv6> router isis WORD" is executed on the interface, it invokes list_delete_all_node to iterate and release the memory of all nodes in the cirtcuit->u.bc.adjdb[1] linked list. However, the nodes are not unlinked during this traversal process, leading to the call of *list->del to delete the data of the linked list nodes.
2. For ISIS, deleting the data of the linked list nodes is done by calling isis_delete_adj. Subsequently, isis_level2_adj_up will be called to iterate and query the cirtcuit->u.bc.adjdb[1] linked list. If there are many neighbors on this interface, accessing the memory of the released linked list nodes may occur.
3. Not limited to ISIS, if the linked list is not unlinked during the deletion of all nodes in process 1, *list->del should not be allowed to iterate through the list again.
The backtrace is as follows:

Dropping the macro enables better compiler type checking.
The macro was not used consistently when reading the lsa size from the
header, so this change also aims to use the replacement inline function
consistently.
Keeping the inline function has (marginal) utility in that it ensures that
the endian conversion is consistently performed.
