FRR supports dynamic capability which is useful to exchange the capabilities
without tearing down the session. ENHE capability was missed to be included
handling via dynamic capability. Let's add it too.
This was missed and asked in Slack that it would be useful.

Currently if you have an interface down event, Zebra
sets the nexthop(s) as !ACTIVE that use it. On
interface up events the singleton nexthops are not being
set as ACTIVE. Due to timing events it is sometimes
possible to end up with a route that is using a singleton
Change singleton nexthops to set the nexthop to ACTIVE.
This will allow the nexthop to be reinstalled appropriately
as well.
I was able to easily reproduce this using sharpd since
it does not attempt to reinstall the routes when a interface
goes up/down.

Route aggregation should be checked after a route is added, and
not before. This is for code flow and consistency.

LaTex doesn't like the Unicon character `≥` which should be represented
by the special sequnce `$\leq$`. Since this is buried all in Sphinx, and
we also have a scrip that look for the character, the easiest fix is to
just use `>=` instead which works without warnings, and without asking to
ignore every warning about the use of every instance of the special char.

With the recent suppoort of multiple sources of RPs, we can assume non static RPs
are BSR RPs. Just make the check explicit for BSR.

On the BSR node itself, RPs shouldn't timeout, becase we know
the node is the BSR, and it is active!

lua_pcall() returns LUA_ERRGCMM in 5.3 which is already deprecated.
The constant LUA_ERRGCMM was removed.
Errors in finalizers are never propagated; instead, they generate a warning.

then finally wait a bit more for SAs to be propagated.

Currently when an aggregate-address is configured, the existing
entry is always removed regardless whether any change is involved.
This would create unnecessary churn of the aggregate route when
the same config is applied for the aggregate address.
The fix is to check for duplicate aggregate-address config.

In some cases, the old_re nhe and the newnhe is same and there is no
point in comparing them both since they are the same. Skip comparing in
such cases.
