bootstrap: Various code improvements

- Do not specify -e twice.
- Use "which" instead of calling commands that might not exist.
- Fix bashism ("==" is C not sh)
- Carefully quote potentially empty variables
- Check command arguments before doing anything
- Rewrite argument checking to be more easily extensible
- Consistent indentation
- UNIX style error messages
