olsrd-watchdog can trigger when the olsrd service is restarted
Such as when a tunnel comes up, or when a config change is
made to olsrd.
procd already monitors olsrd and makes sure it remains running.
With procd we no longer need olsrd-watchdog and can remove it.

Correct all shellcheck "errors" and "warnings" for
/usr/local/bin/* shell scripts.
This is necesary to have Jenkins start publishing test results.
All code worked on nodes but pushed to strict posix compliance
as part of the cleanup.

Since a large number of the BBHNDev team has decided to create firmware fully independent of the BBHN Project the decision has been made to rebrand the firmware to differentiate from the origional BBHN work.
We would like to thank all those whom have worked on the BBHN firmware over the years and all those who continue to work on the firmware under AREDN(TM).
Program went GPLv3 last year but license text was never added to files
Default text to give credit to David as he is listed in all commits and to reference the BBHN Austin team at the same time as they were part of the group of HAM's that started this project.
Using the method suggested by Henning Rogge in 2014
{{{
1) remove file
2) wait 2 intervals
3) if file exists, go to 1)
4) restart olsr, then go to 1)
}}}
With the exception that we currently wait more than 2 intervals.
Even if the script hits a collision at the same time the file is being written the file will already exist from one of the previous writes or the current write.
Removing a file in use is safe as once the FD closes the file contents are fully released.
Additional Advantages:
* Should be more efficient to check if file exists instead of reading the file and comparing date stamps.
* Removing the Perl code moves us one step closer to retiring Perl in the future.
The olsrd watchdog module truncates and writes the latest timestamp every 5 seconds. The olsrd-watchdog script could catch the file during write causing an instant restart.
Changed to want 3 failures before restarting olsrd reducing the chance of collision based restarts.
