Highlights:
- Avoid keywords (this, not) as variable names
- Move yyparse into config.h with other declarations
- All declarations in config.h are assumed guilty until proven innocent
- Some const-correctness
- Casting malloc/calloc returns
Note that we're not building any C++ here yet, this will be introduced
in other commits to replace some of the lib dependencies. Reducing the
number of FreeBSD-specific dependencies we have reduces some friction
for building our bootstrap tools independently in other environments.
