This contains mostly string manipulation, so C++ is much more
convenient.
This commit only changes the things that don't compile in C++:
- turn ?alloc/free into std::vector
- use the C++ version of the translation machinery
- add namespace for enum in pl0t_info struct
Contains minor whitespace fixes.
