feat(library/type_context, library): inout ==> out modifier in type class declarations
...
@kha: I decided to implement this change before I start the
type_context modifications. The change did not affect the corelib and
test suite much. The only annoying problem is that `out` cannot be
used to name locals anymore.

fix(library/tactic/cases_tactic): try to clear input hypothesis when performing dependent elimination
...
The `induction h` tactic tries to clear hypothesis `h` after it is
applied. But, before this commit, `cases h` would only try to clear `h`
when performing non-dependent elimination. This was problematic when
writing tactic scripts for automating proofs.
