These null checks don't make sense because a) these two functions
are never called with a NULL IP address and b) the same pointers are
dereferenced later without any protection. Remove these NULL checks
to make the code less confusing.

This commit fixes all of them except the bgp `recieved` issue due to
it being part of json output. That one will need to go through
a deprecation cycle.

When a BGP next hop tracking (NHT) entry is created for a peer,
display it in the corresponding "show" command output.

In the case of IPv4 route exchange using GUA IPv6 peering, the route install
into the FIB involves mapping the immediate next hop to an IPv4 link-local
address and installing neighbor entries for this next hop address. To
accomplish the latter, IPv6 Router Advertisements are exchanged (the next hop
or peer must also have this enabled) and the RAs are dynamically initiated
based on next hop resolution.
However, in the case of a passive connection where the local system has not
initiated anything, no NHT entry is created for the peer, hence RAs were not
getting triggered. Address this by ensuring that a NHT entry is created even
in this situation. This is done at the time the connection becomes established
because the code has other assumptions that a NHT entry will be present only
for the "configured" peer. The API to create the entry ensures there are
no duplicates.

Create an interface with IP4 link local address 169.254.0.131/25.
In BGP enable the redistribute connected. Now Zebra will not send
the route corresponding to IPV4 link local address. Now made this
interface down and up. Zebra sends the route to BGP.
Zebra should not send this route to BGP.
This Fix would make the behaviour consistent and would not send the
routes corresponding to IPV4 Link local addresses.

In if_netlink.c, when an interface structure, ifp, is first created,
its possible for the master to come up after the slave interface does.
This means, the slave interface has no way to display the master's ifname
in show outputs. To fix this, we need to allow creation by ifindex instead
of by ifname so that this issue is handled.

Say for eg., 256 prefix-list entries are pasted to VTYSH.
This results in BGP processing the events for several minutes.
BGPD starts a timer for 5 seconds when the first dependency configuraion
is received. On timer expiry, BGP process dependent route-maps.
After this processing, BGPD reads the configurations received in the
next 5 seconds and then re-processes the route-maps from the beginning.
This cyclic re-processing consumes time and CPU cycles.
Instead of starting a timer when the first configuration is received,
everytime a configuration is received, the existing timer is reset.
This would mean that all the configurations are read first before the timer
expires. This eliminates the cyclic re-processing.

A race condition causes the failure.
The function "make_info()" sets the path info's peer to
bgp instance's "peer_self" which is created when BGP is first
configured and deleted only when BGP is brought down completely.
A race condition causes the bgp instances's "peer_self" to be
removed before the routes are being pulled off from the aggregate
address.
If the bgp instance's "peer_self" is NULL or, if BGP is being deleted,
the aggregate route must not be reinstalled.

configured with reg-ex.
The CLI to configure the standard format large-communities attribute
accepts regular expressions as well.
For ex., the below configuration is accepted.
"bgp large-community-list standard TEST permit 1:1 100:*"
The code to parse the large-communities does identify the configuration
as invalid however, error returned isn't processed.
The code has to be modified to handle the error.

We used the vrf_id in the rtm_table field of the netlink rtmsg to fetch L3VNI.
But, now we program table_id to rtm_table field instead of vrf_id.
Thus, L3VNI fetched using rtm_table is incorrect.
Instead, use nexthop->vrf_id to fetch the L3VNI.

"show bgp l2vpn evpn neighbors <neighbor> [advertised-routes|routes]' did
not work due to various bugs. First, the command only accepted IPv4
addresses as valid neighbor ID, thereby rejecting unnumbered BGP and IPv6
neighbor address. Second, the SAFI was hardcoded to MPLS_VPN even though
we were passing the safi. Third, "all" made no sense in the command context
and to make the command uniform across all address families, I removed the
"all" keyword from the command.

All FRR Linux packages are built using libcap-dev (or libcap-devel)
installed in the system. Update the build instructions to suggest
FRR developers to do the same. The main motivation for this is that
the seteuid() system call is too expensive and overall less secure
compared to using the Linux capabilities framework.
