Work in progress on the coq backend

- originally based on the Lem backend
- added externs to some of the library files and tests
- added wildcard to extern valspecs in parser
- added Type_check.get_val_spec_orig to return the valspec with the
  function's original names for bound type variables

Note that most of the tests will fail currently
