Clean up scanner_run() and interpret_run(): narrow signatures, fix SoC [SoC/DIP]

Three issues resolved:

1. scanner_run() no longer takes Fype*. New signature:
     scanner_run(List*, Tupel*, char **c_filename_out)
   Verbose-mode list_iterate() and basename extraction moved to
   fype_run() (the composition root), leaving scanner_run() as pure
   tokenizer: open source -> tokenize -> post-process -> return filename.

2. interpret_run() no longer takes Fype*. New signature:
     interpret_run(List *p_list_token, Hash *p_hash_syms)
   Fype* unpacking happens in fype_run(); interpret.h no longer includes
   fype.h. scanner.h no longer includes fype.h either.

3. _CODESTR_INDEX file-global (which made the scanner non-reentrant)
   moved into the Scanner struct as i_codestr_index, initialized to 0
   in scanner_new(). _scanner_has_next_char() and _scanner_get_next_char()
   use p_scanner->i_codestr_index instead.
