Bugfix: Out of date repository build scripts.

Bugfix: Out of date repository build scripts.

The repository build scripts are very much out of date.

A recent bugfix, commit 831e5d8b0dce5279964987baa43201b63c12c203, attempted to partially address this.
It turns out that there is a lot more that needs to be done.

All of the repository build scripts are now updated.

Make sure the copyright parameter is available.

Make sure the "+Q/++quiet" and "+E/++error" parameters are correct and working.

Make sue the "+F/++line_first_no" and "+L/++line_last_no" parameters are working.
Utilize "+F" and "+L" where reasonably possible in the example bootstrap and test scripts.

Improve return status handling.
The goal here is to avoid calling "exit".
The use of "exit" is not safe as under certain conditions it can close terminals that the script is running in.
