Progress: Continue working on completing the remove program.

I discovered that the `fl_directory_do()` could use some improvements while working on this.
Those changes are now made in the FLL project.
Make changes to this project based on the `fl_directory_do()` updates.

I began writing some tests and I encountered several problems and concerns that side-tracked me.

Rename the `kt_remove_operate_file_recurse()` to `kt_remove_operate_file_directory()`.
This should make its design and purpose more clear.

Make sure that the recurse status is processed in the proper order for the file operation directory.
Fix the problem where the recursion is being performed even when the recurse flag is not set.
Add checks to see if the directory is empty or not before deleting when recursion is not enabled.
The flag (called code in this case) needs to accurately reflect the directory status of the file during recursion.
Make sure the recurse error handler uses the top path or the recurse path as appropriate.

Print debug messages before recursion begins.

Add missing `f_status_t` return states to several print functions.
I did not do an exhaustive look (I imagine the TacocaT program needs similar changes).
Fix problems where the program output is being used for the print functions rather than the print output.

The runtime unit tests do not work correctly because the standard outputs are being closed.
Add additional ifdef checks to prevent the set down functions from being called.
