State Transaction Machine
The process_transaction function adds a new edge to the Dag without
executing the transaction (when possible).
The observe id function runs the transactions necessary to reach to the
state id. Transaction being on a merged branch are not executed but
stored into a future.
The finish function calls observe on the tip of the current branch.
Imperative modifications to the environment made by some tactics are
now explicitly declared by the tactic and modeled as let-in/beta-redexes
at the root of the proof term. An example is the abstract tactic.
This is the work described in the Coq Workshop 2012 paper.
Coq is compile with thread support from now on.
