This commit is a follow-up to 123334881a.
Its purpose is to make the environments module abstract again,
by moving the parsing mechanism in its own module.
Consequently, the environments module can be linked earlier again (as
was the case before the commit mentionned above) and can thus be
used in other modules.
This commit contains:
- The initial version of the tool itself, in the ocamltest directory
- The required additions to the main .gitignore and .merlin files.
The integration of ocamltest in OCaml's main build system and its use
in the testsuite are not part of this commit.
Credits go to David Allsopp for
- Extending the computation of ocamlsrcdir to the Windows case
- Making ocamltest compile when flexlink
is being bootstrapped.
