feat(library/init/meta): introv tactic
...
@Armael: this commit implements the `introv` tactic.
The implementation uses an auxiliary `intros_dep` that introduces new
hypotheses with forward dependencies.
The `tactic.introv` tactic implemented at library/init/meta/tactic.lean
is the main implementation, but it is not nice for interactive use since
users would have to write
```
tactic.introv [`h1, `h2]
```
To make it more conveninent to use, we define another
```
meta def introv (ns : parse ident_*) : tactic unit :=
tactic.introv ns >> return ()
```
This one is in the namespace `tactic.interactive`, and
uses parser extensions. The argument `parse ident_*` instructs
the parser to parse 0 or more identifiers and create a term
of type `list name` containing these identifiers.

And `done` is more descriptive anyway.

fix(frontends/lean): fixes #1468
...
@kha I had to add yet another hack to fix this issue.
In notation declarations, names are resolved at notation declaration time.
So, users do not expect them to be resolved again at tactic execution time.
I addressed this problem by wrapping constants occurring in notation
declarations with a "frozen_name" annotation. This transformation is
only performed if m_in_quote is true.
Then resolve_names_fn at elaborator.cpp will not try to resolve the
names again.
This change broke two other modules. `-` notation for inverting
equations at `rw`, and `calc` expressions inside quotes.
The broke for the same reason. They were not expecting the constants
to be wrapped with an annotation.
