XML sample document behaves differently when checked out on Windows where
the source line endings in the test document become `\r\n`.
Alternative would have been to specify that t01.ml needs LF endings in
.gitattributes, but explicitly including the \n and \t in the OCaml string
seems less brittle.
There used to be a limitation to 32 binding groups, which is now lifted by dynamically allocating the groups data if it is too big.
Also:
- Modernize strstubs.c to use the Caml namespace
- Fixed a potential bug with backreferences \\n referring to a nonexistent group.
