Latest set of commits should be reviewable. I updated the PR description with an overview of the commits.

One remaining issue I haven't dealt with yet is `TestCxxFrameFormatRecursive.test` where we set the `plugin.cplusplus.language.function-name-format` variable to `${function.name-with-args}`. Which would cause infinite recursion as `${function.name-with-args}` tries to format according to `plugin.cplusplus.language.function-name-format`. Don't think we've had precendent for something like that yet, so there aren't any safeguards for this
