- Remove commented out code
- Pull std++ related lemmas into a separate file

In this file I will keep all the comments regarding different aspects
of formalisation.

The current prove does not reuse certain lemmas

Following the advice of Amin Timany
generalize all the compatibility lemmas
at the same time by declaring a mask E in a Section.

We are switich away from De Bruijn indices because
1) it's hard to read terms with De Bruijn indices
2) they are making lots of things slower

And improve the proof of the fundamental property

The new _with_lock rule does not mentioned lower level details of the
relational interpretation.

A new formulation allows for doing more work inside HOSL.

Γ ⊨ e ≤log≤ e' : τ <=>
∀ Δ vvs ρ,
  spec_ctx ρ -∗
  □ ⟦ Γ ⟧* Δ vvs -∗
  ⟦ τ ⟧ₑ Δ (e.[env_subst (vvs.*1)], e'.[env_subst (vvs.*2)])

Slightly generalize the way tac_tp_bind works and rewrite the
fundamental property for F_mu_ref_conc using tp_ tactics

Previously [tp_alloc] would just delete [j \Mapsto fill K (Alloc e)]
from the context without a replacement.

- Make sure that the whole project compiles

Almost all tactics are implemented for manipulating expressions in
the [j \Mapsto fill K e].
