A service managed by procd does have a json object with usefull information.
This information could by dumped with the following command.
ubus call service list "{ 'verbose':true, 'name': '<service-name>)'". }"
This line is long and complicated to enter. This commit adds a wrapper
call to the procd service section tool to simplify the input and get the
output faster.
We could now enter the command /etc/initd/<service> info to get the info
faster.

The following command checks if a instance of a service is running.
/etc/init.d/<service> running <instance>
In the variable `$@`, which is passed to the function
`service_running`, the first argument is always the `instance` which
should be checked. Because all other variables where removed from `$@`
with `shift`.
Before this change the first argument of `$@` was set to the `$service`
Variable. So the function does not work as expected. The `$service`
variable was always the instance which should be checked. This is not
what we want.

There are services that have only STOP value set. They are executed only
on shutdown and it is common to use them for system cleanup. There is
one such service shipped directly with base-files, it is 'umount'. Those
work the same way as those with START but enabled does not report them
as enabled although it should have as they can be enabled and disabled
as any other service.
This also changes check from check for executable to check for symbolic
link. The implementation depends on those being links to service file
and it is much cleaner and direct to check for them being links.

Avoid needlessly breaking old initscripts that set EXTRA_COMMANDS. This
will aid in debugging (as it simplifies reverting to an older version of
a package) and unbreaks third-party feeds (and packages that maintain
their OpenWrt initscripts as part of the software's repo instead of the
OpenWrt feed like fastd).
Without this, initscripts that set EXTRA_COMMANDS become completely
unusable, as all default commands like start/stop cease working.

This commit introduces a new function `extra_command` to better format
the help text without having to calculate the indentation in every startup
script that wants to add a new command. So far it looks weird and is not
formatted correctly on some startup scripts.
After using the new `extra_command` wrapper the alignement looks correctly.
And if the indentation is not sufficient in the future, this can be
changed in the function extra_command at a central location.

Commit ed5b9129d7 ("base-files: implement generic service_running")
has added EXTRA_HELP variable, thus overriding already available
EXTRA_HELP text available in other init scripts, resulting in the
missing help text from services like dropbear for example.
So fix this regression by appending EXTRA_HELP text provided by the
other init scripts into the one provided by the script itself.

Adds a default status action for init.d scripts.
procd "service status" will return:
0) for loaded services (even if disabled by conf or dead)
3) for inactive services
4) when filtering a non-existing instance

[rebased, cleaned up]

Purpose of these changes is to introduce a hook for post service
shutdown in a similar fashion to the existing hook service_started. I
found it to be useful to specify a hook that is called once the service
has been stopped and not before the service is stopped like the
stop_service hook does.
The concrete use case I have for this is that I'm running a binary that
takes over the hardware watchdog timer. Said binary unfortunately can
not use ubus directly to tell procd to hand over the watchdog timer so
this has to be done in the service file for the binary in question. In
order to support a clean handover of the watchdog timer back to procd,
the service init script has to dispatch the ubus invocation once the
binary in question has been stopped.

[added commit message, use the same form as other hooks]
When restart is run on an init script, the script traps SIGTERM. This is
done as a workaround for scripts named the same name as the program they
start. In that case, the init script process will have the same name as
the program process, and so when the init script runs killall, it will
kill itself. So SIGTERM is trapped to make the init script unkillable.
However, the trap is retained when the init script runs start, and thus
processes started by restart will not respond to SIGTERM, and will thus
be unkillable unless you use SIGKILL. This fixes that by removing the
trap before running start.

In current state, if there is START but no STOP, enbale()
will return 1 (failure), which is wrong.
Moreover there is no need to check for START/STOP twice.
Instead, add err variable to save success state and
and return it's value.
Also eliminate the need to disable() by using 'ln -sf',
which will first delete the old symlink if one exists.

Bug introduced with 6713694.
I did not count on procd handling reload as mentioned
in this doc:
https://wiki.openwrt.org/inbox/procd-init-scripts
```
procd_set_param file /var/etc/your_service.conf # /etc/init.d/your_service reload will restart the daemon if these files have changed
procd_set_param netdev dev # likewise, except if dev's ifindex changes.
procd_set_param data name=value ... # likewise, except if this data changes.
```
The service would be restarted regardless of any of those params.

This was also working before, with a slightly
different semantic.
[ Original semantic ]
If no reload hooks was implemented, the default one would
kick in, it would return fail, and restart would happen.
This would happen also in the case where a reload hook
would be implemented, it would fail, and it would restart
the service.
[ New semantic ]
The default reload hook calls restart.
Services can implement their own reload.
If reload fails, then the '/etc/init.d/<service> reload'
would return a non-zero code, and the caller can choose
a way to handle this.

Before this patch, doing `/e/c/network restart' will emit the folloing
error by `ubus network.wireless down "{}"' because netifd already quit
by that time.
