Instead of passing glob tactics through the infamous globTacticIn hack and
antiquotation feature of the Ltac syntax, we put them in the interpretation
environment as closures. This should be used everywhere to get rid of this
buggy antiquotation syntax.
This fixes bug #2800.

The [guard] tactic accepts simple tests (on integers) as argument, succeeds if the test passes and fails if the test fails.
Together with [numgoal] can be used to fork on the number of goals of a tactic.
The syntax is not very robust (in particular [guard n<=1] is correct but not [guard (n<=1)]). Maybe tests should be moved to the general parser to allow for more flexibility.

the GTac module. A ['a Gtac.t] is a special case of tactic that
may depend on the current goals, or not. Internally, it construct
a list of results, one for each focussed goal, if the tactic is
actually dependent.
This allows for an interpretation of whole-goal tactic that does
work, which was not the case for the previous implementation,
which did to many Proofview.Goal.enter.

"foobar" constr(x1) ... constr(xn)

in retrieving the arguments in the tactic environment rather than
as directly passed to the TacExtend node.

With ocaml 4.01, the 'unused open' warning also checks the mli :-)
Beware: some open are reported as useless when compiling with camlp5,
but are necessary for compatibility with camlp4. These open are now
marked with a comment.

There are many functions in Tacinterp which use a goal as a proxy for the pair of an environment and an evar_map. But do not build LCF tactics with them. They don't play well with the new style of tactics.
I've changed some of them to explicitely take an environment and an evar_map instead.

Internalization was done relative to a goal. It doesn't make sense in the
case of all:. When we make a tactic with all: the environment for
internalization is taken to be the global environment.

It was a bad idea. The new API based on lists seems more sensible.

On the compilation of Coq, we can see an increase of ~20% compile time on
my completely non-scientific tests. Hopefully this can be fixed.
There are a lot of low hanging fruits, but this is an iso-functionality commit.
With a few exceptions which were not necessary for the compilation of the theories:
- The declarative mode is not yet ported
- The timeout tactical is currently deactivated because it needs some subtle
I/O. The framework is ready to handle it, but I haven't done it yet.
- For much the same reason, the ltac debugger is unplugged. It will be more
difficult, but will eventually be back.
A few comments:
I occasionnally used a coercion from [unit Proofview.tactic] to the old
[Prooftype.tactic]. It should work smoothely, but loses any backtracking
information: the coerced tactics has at most one success.
- It is used in autorewrite (it shouldn't be a problem there). Autorewrite's
code is fairly old and tricky
- It is used in eauto, mostly for "Hint Extern". It may be an issue as time goes
as we might want to have various success in a "Hint Extern". But it would
require a heavy port of eauto.ml4
- It is used in typeclass eauto, but with a little help from Matthieu, it should
be easy to port the whole thing to the new tactic engine, actually simplifying
the code.
- It is used in fourier. I believe it to be inocuous.
- It is used in firstorder and congruence. I think it's ok. Their code is
somewhat intricate and I'm not sure they would be easy to actually port.
- It is used heavily in Function. And honestly, I have no idea whether it can do
harm or not.
Updates:
(11 June 2013) Pierre-Marie Pédrot contributed the rebase over his new stream based
architecture for Ltac matching (r16533), which avoid painfully and expensively
working around the exception-throwing control flow of the previous API.
(11 October 2013) Rebasing over recent commits (somewhere in r16721-r16730)
rendered a major bug in my implementation of Tacticals.New.tclREPEAT_MAIN
apparent. It caused Field_theory.v to loop. The bug made rewrite !lemma,
rewrite ?lemma and autorewrite incorrect (tclREPEAT_MAIN was essentially
tclREPEAT, causing rewrites to be tried in the side-conditions of conditional
rewrites as well). The new implementation makes Coq faster, but it is
pretty much impossible to tell if it is significant at all.

The semantics changed slightly so it may break some scripts, though
it is very unlikely, as they would have to be quite intricated and
poorly written. Indeed, the test-suite passed just fine.

1. Genarg itself which only defines the abstract datatypes needed.
2. Genintern, first file of interp/, defining the intern and subst
functions.
3. Geninterp, first file of tactics/, defining the interp function.
4. Genprint, first file of printing/, dealing with the printers.
The Genarg file has no dependency and is in lib/, so that we can put
generic arguments everywhere, and in particular in ASTs.

constr as argument (rather than openconstr) assumed that the evar_map
output by pretyping was irrelevant as the final constr didn't have any evars.
However, if said constr was defined using pre-existing evars from the
context, the evars may be instantiated by pretyping, hence dropping the
output evar_map led to inconsistent proof terms.
This fixes bug #2739 ( https://coq.inria.fr/bugs/show_bug.cgi?id=2739 ).
Thanks Arthur for noticing it.
Note: change still has the bug, because more serious issues interfered with
my fix.
