The problem is that peer_af_array returns NULL when SAFI is changed to
unicast. We use unicast table, but peer is created and activated under
labeled-unicast, hence we should lookup with a proper SAFI id.
Without this patch peer_af_find() returns NULL and we can't show
PfxSnt in `show bgp summary`.

Without specifying a default afi/safi we get a segfault:
```
(gdb) frame 4
bgp_table_stats (..., afi=32724, safi=SAFI_UNICAST, ...
11349 if (!bgp->rib[afi][safi]) {
(gdb)

The `bgp bestpath bandwidth` command should not be a legal
command. Pull out the `no` form to allow this. Allow
`no bgp bestpath bandwidth` to work as we would expect.

We had already removed the `ip as-path..` command
to have `bgp as-path` but for some reason a `no ip as-path..`
command ALIAS was still around. Kill with extreme prejudice.

Loosen the ONLINK restrictions such that when an upper
level protocol sends us a nexthop with an ONLINK attribute
just ensure that interface is up and usable. ONLINK effectively
means we know what we are doing to the kernel.

Community attributes might have been removed by an inbound route map, so we
should check to ensure they still exist before trying to free them.

This dumps call graph data from LLVM bitcode files into a JSON file.
Specifically for FRR, it understands thread_add_*(), hook_*() and
install_element() so it can provide extra information in these cases.
As a general feature, it tries to track down function pointers as far as
easily feasible.

The netlink_vrf_change() function is called both when a VRF device
is created in the Linux kernel and when it is activated. This
commit changes this function to perform the VRF misconfiguration
detection only when the VRF device is created, as doing the check
twice would cause a false positive followed by a hard failure (not
to mention the double check is unnecessary since the VRF table ID
can't change once the device is created).
Fixes#6319.
