1538615e8c feat(util): allow some math alphanum symbol latin letter variations 
Add the Script, Double-struck, and Fractur blocks from,
https://unicode.org/charts/PDF/U1D400.pdf
to is_letter_like() so they may be bound to variables.

c195d7c2a1 feat(library/tactic/simp_tactic): improve mk_simp_attr 
- An new simp attribute may depend on other existing attributes

- Add `[norm]` simp attribute. It is an extension of the default `[simp]` attribute.
  It should be used to add extra rules for normalizing goals.
  These extra rules are used to produce normal forms and/or reduce the
  number of constants used in a goal. Here is an example coming from a
  discussion with @kha. When working with monads, we may want to
  eliminate `<$>` by using the lemma `f <$> x = x >>= pure ∘ f`.
  This lemma is in the `[norm]` simp set, but it is not in `[simp]`

26da50ab0e feat(library/vm/vm_string): efficient iterator.extract 
@kha I've added

   iterator.extract : iterator -> iterator -> option string

It returns `none` if the iterators are "incompatible".
If this function is inconvenient to use, we can change it and return the
empty string in these cases.

Given iterators `it1` and `it2`, if they are sharing the same string
object in memory, then the cost is O(pos(it2) - pos(it1)).
If not, we have an extra O(N) step where we check whether the strings
being iterated by it1 and it2 are equal (`N` is the size of the strings).
In most applications, I believe the iterators will share the string
object.

I didn't test the code much. BTW, I found an unrelated bug at
vm_string.cpp. So, I'm not very confident this code is rock solid.

587540f11b feat(frontends/lean): add abbreviation command 
This command is not just a cosmetic feature.
We need it to defined `id_rhs` before the tactic framework is defined.
We want `id_rhs` to be used in all definitions generated by the equation
compiler. Right now, it is only used in definitions defined after the
tactic framework.

b7de24715b fix(util/rbtree): make sure traversal methods do not crash if given function updates the tree 
This is a fix for a nasty bug at `type_context::set_instance_fingerprint`.
This method traverses the local context `m_lctx` and invokes `is_class`
which may invoke `whnf`, and `whnf` may temporarily update the local
context. The local context is implemented using a `rb_tree`.
Note that the updates performed by `whnf` are temporary, but it
its representation in memory may be different.
