Squashed: Added integration and standalone tests, read more

This wasn't an easy fix, as it was primarily the test pipelines that
were failing. I resorted to using forced pushes to run the CI, to try
and track down the problems.

The primary cause seems to be the differences in how each supported
platform handles file paths, specifically, slash vs. backslash.

I've also added gdb scripts to set up automated breakpoints, and to run
operations on them to check for issues - the 'gdb_init' files are mostly
empty for the time being.
