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.

This way, we avoid relying on the add_auto_init hook. This hook
is left for the moment, but could probably be removed someday.
We also stop using create_hint_db, which has an effect on the libstack.
This wasn't a problem per se, but could if init_summaries is used more
(for instance to temporary reset coq).

States.freeze takes ~marshallable:bool, so that (only) when we want to
marshal data to disk/network we can ask the freeze functions of the
summary to force lazy values. The flag is propagated to Lib and Summary.

4. context.ml: Rel/Named context and all that;
5. term.ml: derived utility operations on terms; also includes constr.ml

the new Int module. Only the most obvious were removed, so there
are a lot more in the wild.
This may sound heavyweight, but it has two advantages:
1. Monomorphization is explicit, hence we do not miss particular
optimizations of equality when doing it carelessly with the generic
equality.
2. When we have removed all the generic equalities on integers, we
will be able to write something like "let (=) = ()" to retrieve all
its other uses (mostly faulty) spread throughout the code, statically.

instead of a general constr: this is the most common case and does
not loose generality (one can simply define constrs before Hint Resolving
them). Benefits:
- Natural semantics for typeclasses, not class resolution needed at
Hint Resolve time, meaning less trouble for users as well.
- Ability to [Hint Remove] any hint so declared.
- Simplifies the implementation as well.

This instance of gen_tactic_expr was used only to decorate
tactics via Refiner.abstract_tactics and alii, but these
expressions are now ignored by the new proof-engine (no "info"...).

any function of CList in the List namespace (and in particular, this
permits optimized reimplementations of the List functions, as, for
example, tail-rec implementations.

I was afraid that such a brutal refactoring breaks some obscure
invariant about linking order and side-effects but the standard
library still compiles.

To mitigate the lack of a general "info" tactical, let's
introduce some specialized tactics info_trivial, info_auto
and info_eauto that display the basic tactics used when
solving a goal.
We also add tactics "debug trivial" and "debug auto" which
display every basic tactics attempted by trivial or auto.
Triggering the "info" or "debug" mode for auto, eauto, trivial
can also be done now via global options, such as Set Debug Auto
or Set Info Eauto. In case both debug and info modes are
activated, the debug mode takes precedence.
NB: it would be nice to name these tactics "info xxx" instead
of "info_xxx", but I don't see how to implement a "info eauto"
in eauto.ml4 (hence by TACTIC EXTEND) while keeping
a generic "info foo" tactic in g_ltac.ml4 (useful to display
a nice message about the unavailability of the general info).

This adds two experimental features to the typeclass implementation:
- Path cuts: a way to specify through regular expressions on instance names
search pathes that should be avoided (e.g. [proper_flip proper_flip]).
Regular expression matching is implemented through naïve derivatives.
- Forward hints for subclasses: e.g. [Equivalence -> Reflexive] is no
longer applied backwards, but introducing a specific [Equivalence] in the
environment register a [Reflexive] hint as well. Currently not
backwards-compatible, the next patch will allow to specify direction
of subclasses hints.

Suggestion of Tom Prince, that told me that he has adapted the rippling
tactic to use the "nocore" pseudo-database. Since this tactic was the
only user of these optional arguments ?use_core_db, let's remove them.

These annotations are purely optional, but could be quite helpful
when trying to understand the code, and in particular trying to
trace which which data-structure may end in the libobject part
of a vo. By the way, we performed some code simplifications :
- in Library, a part of the REQUIRE objects was unused.
- in Declaremods, we removed some checks that were marked as
useless, this allows to slightly simplify the stored objects.
To investigate someday : in recordops, the RECMETHODS is storing
some evar_maps. This is ok for the moment, but might not be in
the future (cf previous commit on auto hints). This RECMETHODS
was not detected by my earlier tests : not used in the stdlib ?

It appears that registration of hints is the only place (at least
when compiling stdlib) where Univ.universes (the graph of universes)
is stored in vo. More precisely, a Hint Resolve will place in vo
a pri_auto_tactic, which may contain some clausenv, which contain
both a env and a evar_map, each of them containing a Univ.universes
In fact, even env and evar_map are also never stored in vo apart
from hints registration.
Currently, there's nothing wrong in this storing of env / evar_map /
universes. In fact, it seems that every stored universes are actually
empty. Same for env, thanks to awkward lines { cl with env=empty_env }.
But this may hinder potential evolutions of Univ.universes toward a
private per-session representation. Conclusion: it is cleaner
(and not that hard) to store a Term.types instead of the clausenv
in vo, and reconstitute the clausenv at Require-time. On a compilation
of the stdlib, the time effect is hardly noticable (<1%).
NB: a Univ.universes is also stored in initial.coq, but this is a
different story (Write State ...)
