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].

sans examples

Main changes:
- Rewrite cfgG and cfgUR
- Use gen_heap from iris
