pimd: add safety check to OIL add/del
These will corrupt memory if mroute_vif_index is -1 (e.g. interface not
operating.) That shouldn't happen, but it does while doing development
work, so trip an assert rather than corrupting memory.

*: When matching against a nexthop send and process what it matched against
Currently the nexthop tracking code is only sending to the requestor
what it was requested to match against. When the nexthop tracking
code was simplified to not need an import check and a nexthop check
in b8210849b8ac1abe2d5d9a5ab2459abfde65efa5 for bgpd. It was not
noticed that a longer prefix could match but it would be seen
as a match because FRR was not sending up both the resolved
route prefix and the route FRR was asked to match against.
This code change causes the nexthop tracking code to pass
back up the matched requested route (so that the calling
protocol can figure out which one it is being told about )
as well as the actual prefix that was matched to.

bgpd, lib, pimd: Remove sockopt_cork
sockopt_cork is a no-op function that was cleaned up

Fixing the below problem:
Dereferencing a pointer that might be "NULL" "group_dnode"
when calling "yang_is_last_list_dnode" in api pim_process_no_rp_cmd
Although there is no NULL pointer dereference since
yang_dnode_exists is called before using the dnode.
So removing the unnecessary yang_dnode_exists api call
and directly get the node and if node does not exists,
return.

zebra: let /32 host route with same IP cross VRF
Contraints of host routes are too strict in current code:
Host routes with same destination address and nexthop address are forbidden
even when cross VRFs.
Currently host routes with different destination and nexthop address can cross
VRFs, it is ok. But host routes with same addresses are forbidden to cross VRFs,
it is wrong.
Since different VRFs can have the same addresses, leak specific host route with
the same nexthop address ( it means destination address is same to nexthop
address ) to other VRFs is a normal case.
This commit relaxes that contraints. Host routes with same destination address
and nexthop address are forbidden only when not cross VRFs.

pim6d: Return type and parameter changes for api pim_rp_del_config
1. Return value of this function pim_rp_del_config is nowhere used.
So made it as a void function.
2. Paramater const char *rp is first converted to string from prefix
in the caller and then back to prefix in this api pim_rp_del_config.
Fixed it by directly passing the address instead of string.

lib, vtysh: report lost messages on live log
The vtysh live logs don't try to buffer messages when vtysh isn't
reading them fast enough. Either the kernel has space and can accept
messages without delay, or it doesn't and we continue on.
While this is intentional (otherwise slow vtysh could block a routing
daemon), at least give the user an indication if messages were dropped.

Modified the bgp_clear_stale_route function to have
better indentation, but in the process changed some
`continue;` statements to `break;` which modified
the looping and caused stale paths to not always be
removed upon an update.
To reproduce: A ---- B, setup with addpath and GR
One side has a prefix with nhop1 and nhop2, kill one
side and then resend the same prefix with nhop3,
paths nhop1 and 2 become stale and never removed.
Code inspection clearly shows that that `continue`
statements became `break` statements causing the
loop over all paths to stop prematurely.
The fix is to change the break back to continue
statements so the loop can continue instead of
stopping.

lib: fix log target removal when singlethreaded
While running singlethreaded, the RCU code is "dormant" and rcu_free is
an immediate operation. This results in the log target loop accessing
free'd memory if a log target removes itself while a message is printed

Just use frr_each_safe to avoid this issue.
