[PATCH 12/12] test-lib-functions: split out {debug,path,text} helpers
Split out the debug, path and text miscellaneous helpers into their own files. The "test -[efsd]" etc. helpers were not all in one place in test-lib-functions.sh, I think moving them into their own file makes it easier to follow the code.
The same goes for the miscellaneous text munging helpers, and the debug code that was early in the file.
As viewing this commit with diff.colorMoved=true will show there's no functional changes here. The only added/removed lines are comments and whitespace. The rest is all moving of existing code into new files.
