There was a historical blurb at the top of the process architecture
document that in several instances caused some confusion regarding
whether or not FRR supports multithreading. Remove this paragraph and
replace it with a summary of the page contents.

Currently I get bgp_instance_del-test as well as bgp_l3vpn_to_bgp_vrf
failures every ~3-4 runs when under a 40 parallel run with micronet.
Examination of the failure and passing cases always leads to the
failures showing convergence of bgp bestpath immediately after
the show commands to ensure that the routes are there.
Modify the code to look for the fact that the vrf has
converged from routes being passed around across vrf's
and ensure that bestpath has run on them.

When "update-source IFNAME" is used for the neighbor, p->update_source
is set to NULL, so we can't use it as a source address and should use
the address from p->su_local.

Because this test can be run in either netns vrf mode or vrflite
vrf mode, the default vrf name has different name. When netns mode
is chosen, vrf0 name is chosen as default name, while when vrflite
mode is chosen, default name is chosen. Remove the vrf keyword from
the expected dump.

42d4b30e introduced per-VRF table manager.
Table manager is allocated when the VRF is created, but it is freed when
the VRF is disabled. When this VRF is re-enabled, zebra ends up with
table manager being NULL pointer and it crashes on any dereference.
Table manager should be freed when the VRF is deleted, not when it's
disabled.

Currently, we automatically delete an inactive VRF when its last
interface is deleted. This code introduces a couple of crashes because
of the following problems:
- vrf_delete is called before calling if_del hook, so daemons may try to
dereference an ifp->vrf pointer which is freed
- in if_terminate, we continue to use the VRF in the loop condition
after the last interface is deleted
This check is needed only when the interface is deleted by the user,
because if the interface is deleted by the system, VRF must still exist
in the system. Move the check to appropriate places to fix crashes.

We don't receive interface down/delete notifications from kernel when a
netns is deleted. Therefore we have to manually replicate the necessary
actions, otherwise interfaces are kept in the system with stale pointers
to the deleted netns.
