Issue: bgpd got kill due to out of memory, when show bgp
neighbor json and show ip bgp neighbor <ip> routes json
commands executed multiple times in a setup having 320554
routes.
RCA: Heap allocated for bgpd keeps increasing. This is verified
using top command and show memory command.
Memleak Fix-1: show ip bgp route json command
When dumping a large bit of table data via bgp_show_route
and if there is no information to display for a particular
struct bgp_node *` the data allocated via json_object_new_array()
is not freed. This is resolved now.
Memleak Fix-2:
The function bgp_peer_counts() doesn't free the memory allocated for
json_loop when there is No such neighbor or address family. This is
fixed now.

The RFC 8212 changes keep being questioned. Update the documentation
a bit more to help the end user figure it out themselves?
At the very least I can just now quote the doc link for this section
when someone asks the question.

When debugging in bgp is turned on for route-map processing
it would be awful nice to know what afi-safi we are working on
for the particular route-map. Especially when using a route-map
across different peers and different afi/safi's

The `struct ecommunity` structure is using an int for a size value.
Let's switch it over to a uint32_t for size values since a size
value for data can never be negative.

Calling fpm_nl_enqueue we should expect a it fit or not
return value on the outgoing stream. This is not necessary
to check here because the while loop where we are checking this
already has ensured that the data being written will fit.

In the function bgp_adj_out_set_subgroup, the attr pointer
is already derefed in all paths leading to a test for NULL.
You cannot pass a NULL attribute in since the whole function
would just immediately crash.

Tests were timing out in our test system due to lost packets and
flakiness of the lower end systems. Just set the timers to 3/10
and give them plenty of time to converge.

Setting `zebra route-map delay-timer 0` completely turns of any
route-map processing in zebra. Which is completely wrong. A timer
of 0 means `do it now`.

New test does this:
a) Ensures that we run the correct number of times given two
`ip protocol X` commands( ie we do not run the route-map application
against all routes, only those affected )
b) Ensure that when we modify the route-map the state ends up sane
this includes making a static route depend on a sharp route that
gets removed from the change of the sharp route-map
c) Ensure that the kernel routes are correct.
