a62949c49b refactor: add type LevelMVarId (and abbreviation LMarId) 
Motivation: make sure we do not mixup metavariable ids for
expression and universe level.

2a940dd4ae feat: add Expr.collectFVars, LocalDecl.collectFVars, Pattern.collectFVars, and AltLHS.collectFVars 
They are all in `MetaM`.

These are helper functions for issue #1237. We need to "cleanup" the
local context before trying to compile the match-expression.

058aea8922 fix: withSaveInfoContext at Inductive.lean 
It was in the context of `withInductiveLocalDecls`. This introduced
unnecessary `_root_` in the info view and hover information.

For example, when hovering over
```lean
inductive Ty where
  | int
  | bool
  | fn (a r : Ty)
```
We would get `Ty.int : _root_.Ty` when hovering over the `int`.

272dd5533f chore: style use · instead of . for lambda dot notation 
We are considering removing `.` as an alternative for `·` in the
lambda dot notation (e.g., `(·+·)`).
Reasons:
- `.` is not a perfect replacement for `·` (e.g., `(·.insert ·)`)
- `.` is too overloaded: `(f.x)` and `(f .x)` and `(f . x)`. We want to keep the first two.

4ee131981d feat: in an inductive family the longest fixed prefix of indices is now promoted to parameters 
This modification is relevant for fixing regressions on recent changes
to the auto implicit behavior for inductive families.

The following declarations are now accepted:
```lean
inductive HasType : Fin n → Vector Ty n → Ty → Type where
  | stop : HasType 0 (ty :: ctx) ty
  | pop  : HasType k ctx ty → HasType k.succ (u :: ctx) ty

inductive Sublist : List α → List α → Prop
  | slnil : Sublist [] []
  | cons l₁ l₂ a : Sublist l₁ l₂ → Sublist l₁ (a :: l₂)
  | cons2 l₁ l₂ a : Sublist l₁ l₂ → Sublist (a :: l₁) (a :: l₂)

inductive Lst : Type u → Type u
  | nil  : Lst α
  | cons : α → Lst α → Lst α
```

TODO: universe inference for `inductive` should be improved. The
current approach is not good enough when we have auto implicits.

TODO: allow implicit fixed indices that do not depend on indices that
cannot be moved to become parameters.

7b84b4cdaa fix: improve inductive indices elaboration 
TODO: convert fixed indices to parameters. Motivation: types such as
```lean

  | mk : Foo []
```
Users should not need to write
```lean
inductive Foo {α} : List α → Type
  | mk : Foo []
```
