better-org branch cleanup

[truedat101]

Here is a running list of things that should be addressed in this branch:

• reorg roadmap : maybe a doc outlining what tasks are on the road to better-org
• missing #include "sal.h" ... presumably this is a personal local file or something generated
• outdated dependencies in third party
• recommendations on top development tools (VSCode in particular, CLion optionally), any configuration needed in .vscode for include paths, plugins required or recommended for vscode
• misc posix porting preprocessor directives needed to fix includes in some cases
• rf_utf8_stats undefined ... appears an entire chunk of utf8.h and chars.c needs to get pulled together

I will update this as I have time.
