When using a regex (or anything that uses `\?` escapes) in python, raw
strings (`r"content"`) should be used so python doesn't consume the
escapes itself. Otherwise we get either broken behavior and/or
`SyntaxWarning: invalid escape sequence '\['`

CLI show callbacks should be defined in frr_ripd_cli_info instead of
frr_ripd_info, because only the former is loaded by mgmtd and only its
callbacks are getting called for config output.

Vtysh has been improved to startup very quickly this exposed a race in this
test, where the `clear ip rip...` command ran before the test client that
handles it had finished connecting to mgmtd. Add a retried check for the test
client being connected before issuing the `clear ip rip ...` test command.

When running bfd_bgp_cbit_topo3 and an intial connection
goes wrong, try to connect again as fast as possible as
that the timer is 2 minutes otherwise and the test will
never come back from it.

This test is frequently failing in the upstream CI. Most
log failures are stating that we expected something like
1 million routes but we have 900k+. Looks like the system
is just loaded a bit more than expected. Let's give these
tests a bit more time to complete.

Store a parsed and built graph of the CLI nodes in vtysh, rather than
parsing and building that graph every time vtysh starts up.
This provides a 3x to 5x reduction in vtysh startup overhead:
`vtysh -c 'configure' -c 'interface lo' -c 'do show version'`
- before: 92.9M cycles, 1114 samples
- after: 16.5M cycles, 330 samples
This improvement is particularly visible for users scripting `vtysh -c`
calls, which notably includes topotests.

There is entirely no point to these being conditional. And pull them up
so the upcoming pre-parse code can work on a clean slate.

The command graph has its tail end nodes pointing at the
`struct cmd_element` rather than a `struct cmd_token`. This is a bit
weird to begin with, but becomes very annoying for the python bindings
where there is just no `struct cmd_element`.
Create a `CMD_ELEMENT_TKN` type for `cmd_token` instead, and replace the
tail end token in the python bindings with an instance of that.

Expose all of the struct members of cmd_token, and retrieve them
dynamically rather than copying them around. The problem with copying
them is that they can change as a result of merge(), and if there is an
existing wrapper object around it will not have its copy updated to
match.

FORK_TKN's join node is already exposed, mirror to expose JOIN_TKN's

The number of nodes in a graph will change as soon as cmd_graph_merge is
supported as an operation, therefore size this dynamically.

Use alloced=0 to indicate that the array used in a vector is not in fact

When the prefix-list is not found, show which AFI is the real one we are
looking for.
E.g.: looking at this output is not clear:
```
[RYF1Z-ZKDRS] route_match_address_prefix_list: Prefix List p1 specified does not exist defaulting to NO_MATCH
```
route_match_address_prefix_list() is called by route_match_ipv6_address_prefix_list(),
and route_match_ip_address_prefix_list().
