After `<daemon_name> is not running` message vtysh does not return

`vtysh -c configure -c "router ospf"` it prints the message to stderr,
but returns 0.
This commit will make vtysh return error when not in interractive mode.
But if you run commands from vtysh, you will still be able to enter

A simple strcmp-based sorting done by `config_add_line_uniq` breaks the
correct advanced sorting of static routes done by staticd. We don't
actually need to check vrf node commands for uniqueness as all commands
are daemon specific, so let's use simple `config_add_line` that doesn't

- only zebra outputs the netns related config
- zebra notifies other daemons about netns attachment

There is a possibility that the same line can be matched as a command in
some node and its parent node. In this case, when reading the config,
this line is always executed as a command of the child node.
For example, with the following config:
```
router ospf
network 193.168.0.0/16 area 0
!
mpls ldp
discovery hello interval 111
!
```
Line `mpls ldp` is processed as command `mpls ldp-sync` inside the
`router ospf` node. This leads to a complete loss of `mpls ldp` node
configuration.
To eliminate this issue and all possible similar issues, let's print an
explicit "exit" at the end of every node config.
This commit also changes indentation for a couple of existing exit
commands so that all existing commands are on the same level as their
corresponding node-entering commands.
Fixes#9206.

pce-config, pce and pcc node-entering commands in vtysh include no-form,
which is incorrect. Currently, when user passes a no-form command like
`no pcc`, vtysh enters the node while pathd deletes the node and this
leads to a desynchronization.
Regular and no-form commands should be defined separately to fix this.

Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

This new dynamic module makes pathd behave as a PCC for dynamic candidate path
using the external library pcpelib https://github.com/volta-networks/pceplib .
The candidate paths defined as dynamic will trigger computation requests to the
configured PCE, and the PCE response will be used to update the policy.
It supports multiple PCE. The one with smaller precedence will be elected
as the master PCE, and only if the connection repeatedly fails, the PCC will
switch to another PCE.

This new daemon manages Segment-Routing Traffic-Engineering
(SR-TE) Policies and installs them into zebra. It provides
the usual yang support and vtysh commands to define or change
SR-TE Policies.
In a nutshell SR-TE Policies provide the possibility to steer
traffic through a (possibly dynamic) list of Segment Routing
segments to the endpoint of the policy. This list of segments
is part of a Candidate Path which again belongs to the SR-TE
Policy. SR-TE Policies are uniquely identified by their color
and endpoint. The color can be used to e.g. match BGP
communities on incoming traffic.
There can be multiple Candidate Paths for a single
policy, the active Candidate Path is chosen according to
certain conditions of which the most important is its
preference. Candidate Paths can be explicit (fixed list of
segments) or dynamic (list of segment comes from e.g. PCEP, see
below).
Configuration example:
segment-routing
traffic-eng
segment-list SL
index 10 mpls label 1111
index 20 mpls label 2222
!
policy color 4 endpoint 10.10.10.4
name POL4
binding-sid 104
candidate-path preference 100 name exp explicit segment-list SL
candidate-path preference 200 name dyn dynamic
!
!
!
There is an important connection between dynamic Candidate
Paths and the overall topic of Path Computation. Later on for
pathd a dynamic module will be introduced that is capable
of communicating via the PCEP protocol with a PCE (Path
Computation Element) which again is capable of calculating
paths according to its local TED (Traffic Engineering Database).
This dynamic module will be able to inject the mentioned
dynamic Candidate Paths into pathd based on calculated paths
from a PCE.

This is a full rewrite of the "back end" logging code. It now uses a
lock-free list to iterate over logging targets, and the targets
themselves are as lock-free as possible. (syslog() may have a hidden
internal mutex in the C library; the file/fd targets use a single
write() call which should ensure atomicity kernel-side.)
Note that some functionality is lost in this patch:
- Solaris printstack() backtraces are ditched (unlikely to come back)
- the `log-filter` machinery is gone (re-added in followup commit)
- `terminal monitor` is temporarily stubbed out. The old code had a
race condition with VTYs going away. It'll likely come back rewritten
and with vtysh support.
- The `zebra_ext_log` hook is gone. Instead, it's now much easier to

frr-reload.py has many special case rules that did not consider ldpd
at all. Specifically:
1. The bulk of ldp configuration comes in a big 'mpls ldp' context, which was
previously considered a single-line context as it started with 'mpls'. This
rule should only apply to labels and lsps.
2. ldp has a 'router-id' config line that fell into the same rule as the above
one. It should not be considered a single-line context as more ldp
configuration can follow.
3. enabled interfaces should not end their context. A better fix
would actually require popping a new context for each interface
in case there is any interface-specific config, but at least this
fix will address the most common use case.
4. when declaring pseudowires, any line with 'member pseudowire XXX' should
be considered a sub-context of the 'l2vpn YYY type ZZZ' context. Without
this fix, changes in the first psuedowire declared would not correctly
be processed (e.g. removing a 'control-word exclude' line would not
be picked up).

The right way to implement this command in vtysh is the following:
* Send the command to each running FRR daemon;
* Collect the command output from each daemon;
* Parse the text outputs into libyang lyd_node structures. Then merge
all these data trees into a single one. Finally, print the merged
data trees to the standard output (libyang will take care of
combining duplicate nodes as necessary).
What this commit does is to allow vtysh to send the "show yang

parameter). It's a quick workaround to allow us to write topotests

VRF context blocks have a context-specific exit command in order to
explicitly force an exit to the top level config node. This command
exists because 'ip route' commands are accepted in both VRF_NODE and
CONFIG_NODE, so static routes intended to be accepted in CONFIG_NODE
that immediately follow a VRF_NODE block will be shoved into the
VRF_NODE block unless the VRF context is explicitly exited.
However, because this is a command that exits to CONFIG_NODE, vtysh -m
should be printing an `end` at the end of the context, since
frr-reload.py relies on this context ender to know when it's back in
CONFIG_NODE. But since this is the only explicit context exit command
that also exits to CONFIG_NODE we don't really have a good way of doing
this already. Hence this god-awful patch.

Now that multiple daemons understand nexthop-groups, we need
to ensure that vtysh doesn't double print out the individual
nexthops that are part of a nexthop-group.

When using pam for authentication, the code just silently
fails and gives no indication to the end user what has gone
wrong. Try to increase messaging about what has gone wrong
by outputting some more data.

clippy boilerplate for those commands as well.

Although the RFC states hostname length should be < 255 chars,
FRR allows infinite length technically. However, when you try
to set a hostname > 80 chars, you would immediately notice a crash.
RCA: Crash due to buffer overflow. Large buffer sprintf'd into smaller
buffer. Usage of sprintf function instead of snprintf which is safer.
