13c532d0d4 fix(*): truncation bugs 
- Lean strings (like std::string) may contain null characters. The
  codebase was ignoring this issue.

- We now have a wrapper `string_ref` for wrapping Lean string objects in
  C++. This wrapper also implements correctly the coercions std::string <-> string_ref.
  Remark: I also found a few places where the code relies on the
  following property which is not true
  Forall s : std::string, std::string(s.c_str()) == s

- `name` object wrapper was assuming that all numerals were small
  `nat` values. This is true in most cases, but the system would
  crash when processing if it is a big number.

- The commit tries to make sure runtime/util/kernel are correct.
  Modules that will be deleted contain many `TODO` comments
  indicating they may crash and/or produce incorrect results
  when strings contain null characters and numerals are big.

@kha: I thought about using `string` instead of `string_ref`.
We consistently use `std::string`. So, it should be fine, but I
was concerned about code readability.

After we bootstrap Lean4, we will be able to delete `lean::list`
template, and rename `lean::list_ref` to `lean::list`.

I am going to add `pair_ref` for wrapping Lean pair objects.
If we use `lean::string` instead of `lean::string_ref`, then
we should also use `lean::pair` instead of `lean::pair_ref`.
But, there is a problem in this case since we have
https://github.com/leanprover/lean4/blob/master/src/util/pair.h#L13
:(

fe2d416cde fix(runtime,util,kernel): should not use strcmp to compare Lean string objects 
Reason:
- UTF8 encoding
- Lean strings may contain null char. That is, null char is not an end
  of string delimiter like in C. Lean string objects are similar to std::string
