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.

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.

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.
