This is very useful to check whether a command disappeared from a
specific daemon (by comparing against an earlier output of
"grammar find-ambiguous printall nodescan")

The vtysh preprocessing stuff doesn't like the first argument to

These have copies in vtysh that do the node-switch locally and are
listed in extract.pl's ignore list. The ignore list however is
redundant since DEFUN_NOSH does the same thing...

* ldpd is built by default in all platforms, it's not necessary to
provide --enable-ldpd anymore;
* Remove comment about ldpd not being tested on OpenBSD, it works very
well on this platform;

The format of the terse output of several ldpd's show commands was copied
from the OpenBSD's ldpctl(8) control program. In the process of doing
that I forgot to replace the occurrences of '\n' with VTY_NEWLINE.

The previous algorithm wasn't failsafe for full configuration reloads
where several pseudowires can be inserted or removed at the same
time. This patch introduces a much simpler logic that solves the problem
in a better way.

The original ldpd(8) daemon in OpenBSD doesn't allow the user to put
non-existing interfaces in the configuration file. For this reason,
the l2vpn_if_find() and l2vpn_pw_find() functions take an ifindex as
an argument. In FRR's ldpd we can put non-existing interfaces in the
configuration, and they are activated as soon as they are available. For
this reason, we can't lookup interfaces by their ifindex in this port.
The l2vpn_if_find_name() and l2vpn_pw_find_name() functions were
introduced to address this issue. However, since the "find-by-ifindex"
functions are not being used anymore, we can just remove them and rename
the *_find_name() functions removing the "_name" suffix.

The rationale here is to do something very similar to what the original
OpenBSD's ldpd(8) does to reload configuration files:
* create a new empty base configuration (vty_conf);
* parse the configuration file and store the result in vty_conf;
* merge the new configuration into the current configuration.
To do this, introduce a new global variable called "sighup" so that ldpd
doesn't attempt to merge vty_conf into ldpd_conf for each command in
the configuration file, which would be very disruptive. vty_conf should
be merged only after the whole configuration file is parsed in order to
avoid taking actions like shutting down neighbors when not necessary.

Only the parent process should handle the SIGHUP signal, but we need
to make sure that this signal is ignored in the child processes so a
command like "killall -SIGHUP ldpd" won't kill ldpd.

The logic to make configuration changes in ldpd is as follows:
1 - duplicate the current configuration;
2 - modify the duplicated configuration (delta);
3 - merge the duplicated configuration into the current configuration.
We can however change things a little bit in order to simplify the code.
If we provide a global vty_conf variable and make sure that it's
always an up-to-date duplicate of ldpd_conf, then we don't need to call
ldp_dup_config() in the callback of each configuration command. Instead
of that, we just need to duplicate ldpd_conf in the startup of the daemon
and in the end of the ldp_reload() function. Doing this is safe because,
due to the single-threaded nature of the parent process, it's impossible
to have multiple requests to change the configuration at the same time.
Also, we can remove the *_ref() functions and do something much simpler
instead. The problem we have to deal with here is that VTY_GET_CONTEXT()
returns a pointer to an element of ldpd_conf, and what we want is a
pointer to an element of vty_conf (e.g. an l2vpn). To solve this,
we just need to look for the equivalent element inside vty_conf using
standard functions from ldpd like l2vpn_find() and others.

This solves a bug where log files created with "log file" were being
created root-owned. So, inserting the "log file" command multiple times
with the same path would fail giving a permission denied error.
Also, rearrange the main() function to call start_child() as soon as
possible to avoid a bunch of unnecessary initializations in the forked
processes.

This adds a "-M" option to each daemon, to load dynamic modules at
startup. Modules are by default located in /usr/lib/frr/modules (lib64
if appropriate). Unloading or loading at runtime is not supported at
this point to keep things simple.
