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 meta-exception was already almost unused, just to distinguish
exceptions during parsing or interp.
Some code cleanup btw

Currently :
- only Admitted uses the Unsafe return status
- the status is ignored in coqtop
- Coqide sees the status but apparently doesn't use it for colouring (I'm not
sure why, but then again, it's not as if I understood coqide's code or
anything)

Meanwhile, a simplified interface is provided in loc.mli.
This also permits to put Pp in Clib, because it does not depend on
CAMLP4/5 anymore.

Migrate the backtracking code from ide_slave.ml into a new backtrack.ml.
In particular the history stack of commands that used to be there is now
non-coqide-specific.
** Adapted commands **
- "Show Script": a basic functional version is restored (and the printing
of scripts at Qed in coqtop). No indentation, one Coq command per line,
based on the vernac_expr asts recorded in the history stack, printed via
Ppvernac.
- "Back n" : now mimics the backtrack of coqide: it goes n steps back
(both commands and proofs), and maybe more if needed to avoid re-entering
a proof (it outputs a warning in this case).
- "BackTo n" : still try to go back to state n, but it also handles the
proof state, and it may end on some state n' <= n if needed to avoid
re-entering a proof. Ideally, it could someday be used by ProofGeneral
instead of the complex Backtrack command.
** Compatible commands **
- "Backtrack" is left intact from compatibility with current ProofGeneral.
We simply re-synchronize the command history stack after each Backtrack.
- "Undo" is kept as a standard command, not a backtracking one, a bit like
"Focus". Same for "Restart" and "Abort". All of these are now accepted
in coqide (Undo simply triggers a warning).
- Undocumented command "Undo To n" (counting from start of proof instead of
from end) also keep its semantics, it is simply made compatible with
the new stack mechanism.
** New restrictions **
We now forbid backtracking commands (Reset* / Back*) inside files
when Load'ing or compiling, or inside VernacList/VernacTime/VernacFail.
Too much work dealing with these situation that nobody uses.
** Internal details **
Internally, the command stack differs a bit from what was in Ide_slave
earlier (which was inspired by lisp code in ProofGeneral). We now tag
commands that are unreachable by a backtrack, due to some proof being
finished, aborted, restarted, or partly Undo'ed. This induce a bit of
bookkeeping during Qed/Abort/Restart/Undo, but then the backtracking code
is straightforward: we simply search backward the first reachable state
starting from the desired place. We don't depend anymore on the proof
names (apart in the last proof block), It's more robust this way
(think of re-entering a M.foo from an outside proof foo).
Many internal clarifications in Lib, Vernac, etc. For instance
"Reset Initial" is now just a BackTo 1, while "Reset foo" now calls
(Lib.label_before_name "foo"), and performs a BackTo to the corresponding
label.
Concerning Coqide, we directly suppress the regular printing of goals
via a flag in Vernacentries. This avoid relying on a classification
of commands in Ide_slave as earlier.

Util only depends on Ocaml stdlib and Utf8 tables.
Generic pretty printing and loc functions are in Pp.
Generic errors are in Errors.
+ Training white-spaces, useless open, prlist copies random erasure.
Too many "open Errors" on the contrary.

too late, in a global environment which was no longer the correct one,
leading to the failure of error printing (hence an anomaly) in case
the command modified the state in several steps.
Now, errors raised by vernac commands are processed in the same
(intermediate) state they were raised from, just before rolling back
to the original state.
that modify the state in several
Now, errors raised by vernac commands that modify the state in several
steps (say S1, S2, ..., Sn) are processed in the state they were
produced in (S1, S2, ... Sn-1),

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

dev/ocamlweb-doc has been erased. I hope no one still use the
"new-parse" it generate.
In dev/,
make html will generate in dev/html/ "clickable version of mlis". (as
the caml standard library)
make coq.pdf will generate nearly the same awfull stuff that coq.ps was.
make {kernel,lib,parsing,..}.{dot,png} will do the dependancy graph of
the given directory.
ocamldoc comment syntax is here :
http://caml.inria.fr/pub/docs/manual-ocaml/manual029.html
The possibility to put graphs in pdf/html seems to be lost.

Coq use case are mostly thoses :
- parsing a char stream to get a vernac expr
- evaluating a vernac expr with backtracking
- turning a knob with a vernac expr, no backtracking
- loading an entire file
- compiling an entire file
- backtracking (no clean API for this yet)
- peeking Coq state info (no clean API for this yet)

- Le parsing se fait maintenant via "constr_expr" au lieu de "Coqast.t"
- "Coqast.t" reste pour l'instant pour le pretty-printing. Un deuxième
pretty-printer dans ppconstr.ml est basé sur "constr_expr".
- Nouveau répertoire "interp" qui hérite de la partie interprétation qui
se trouvait avant dans "parsing" (constrintern.ml remplace astterm.ml;
constrextern.ml est l'équivalent de termast.ml pour le nouveau
printer; topconstr.ml; contient la définition de "constr_expr";
modintern.ml remplace astmod.ml)
- Libnames.reference tend à remplacer Libnames.qualid
