The `conversions` and `ranges` files had separate generators, which
shared some functionality through a 3rd python module, and were
quite similar to each other -- but also had some differences.
Moreover, as they were separate scripts, nothing forced to keep the
outputs in sync (to re-generate them at the same time from the same
inputs).
To fix these maintainability issues, this patch
- merges the two python files and part of the 3rd utility module
into a single script while keeping the existing functionality,
- names the new file `gen-unicode.py` to align better with other
generator script in `tools`, and
- adds some extra documentation how to retrieve the input files
(as they are not part of the repository).
The refactoring affected the utility module as well, so this patch
also
- renames `c_source_helper.py` to `gen_c_source.py` (again, for
naming consistency),
- reorganizes some of its functions not to export module-local
helper functions, and
- adapts `js2c.py`, as it also uses this utility module.
