bbc1f4d461 fix: throwAppTypeMismatch should be polymorphic 
We use it from `TermElabM` and `MetaM`, and they have different
`TermElabM` implementations.

05e5d934d3 feat: change default precedence for new syntax 
Now, the following example produces a syntax error.
```lean
macro "foo!" x:term : term => `($x + 1)

check id foo! 10
```

@Kha, I think the heuristic is simple and defensible.
If the new syntax starts and ends with token, than the precedence is
`maxPrec`. Otherwise, it is `leadPrec`.

see #180

dc9626ceab feat: try to improve weird error message 
@Kha Before this commit, we were producing the error "expected command" at the `let` token
```lean
check id let x := 1; x
```
The new error is "expected command, but found term; this error may be
due to parsing precedence levels, consider parenthesizing the term".

The example above looks artificial, but it will happen all the time as
users start to define their own notation.

cab56d1e1b chore: do not invoke the hooks from addImported 
@Kha I am working on issue
https://github.com/leanprover/lean4/issues/175

I am using solution 2 described there. The hooks will be at `AttrM`
instead of `CoreM`.

AFAICT code deleted by this commit is not necessary.

151e877513 refactor: seal EnvExtension type 
The motivation is to prevent users from tinkering with its internal
implementation details that rely on unsafe features.
The new test crashed before this commit.

3ee9cdd2dc doc: document issue 
@Kha One possible fix: we store `currNamespace` and `openDecls` at `CoreM`.
The issue is similar to the one we had with the pretty printer.
