Since record cannot be recursive, induction principles for them are
just wasted ressources. With this patch, we turn off there generation
by default. The flag "Set/Unset Record Elimination Schemes" allows
to start producing them again.
For compatibility, we adapt "induction" and similar tactics that
rely on the existence of induction principles : on a record,
"induction" is now silently converted into "destruct".

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.

- Clib that does not depend on camlpX and is made to be shared by all coq
tools/scripts/...
- Lib that is Coqtop specific
As a side effect for the build system :
- Coq_config is in Clib and does not appears in makefiles
- only the BEST version of coqc and coqmktop is made
- ocamlbuild build system fails latter but is still broken
(ocamldebug finds automatically Unix but not Str. I've probably done something wrong here.)

Sortclass].

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.

This command isn't trivial to port to the forthcoming evolution of
backtracking in coqtop. Moreover, it isn't clear whether this
"Delete" works well in advanced situation (was not updating
frozen states).

The optimisation done of Namegen.visibly_occur_id did not preserve
the previous behavior when pr_constr/constr_extern/detype were
called on a term with free rel variables. We backtrack on it to
go back to the 8.2 behavior.
Seized this opportunity to clarify the meaning of the at_top flag
in constrextern.ml and printer.ml and to rename it into
goal_concl_style. The badly-named at_top flag was introduced in
Coq 6.3 in 1999 to mean that when printing variables bound in the
goal, names had to avoid the names of the variables of the goal
context, so as to keep naming stable when using "intro"; in
r4458, printing improved by not avoiding names that were short
names of global definitions, e.g. "S", or "O" (except when the
at_top flag was on for compatibility reasons).
Other printing strategies could be possible in the
non-goal-concl-style mode. For instance, all bound variables
could be made distinct in a given expression, even if no clash
occur, therefore following so-called Barendregt's
convention. This could be done by setting "avoid"
to "ids_of_rel_context (rel_context env)" in extern_constr and
extern_type (and then, Namegen.visibly_occur_id could be
re-simplified again!).

Added support for recursive entries in ARGUMENT EXTEND, for right-hand

referring to "loc". Also fixed parsing level of initial value in

"f atomic_tac" as a short-hand for "f ltac:(atomic_tac)" for "f" an
Ltac function - see Tacinterp.add_primitive_tactic).
More precisely, when parsing "f ref" and "ref" is recognized as the
name of some TACTIC-EXTEND-defined tactic parsable as an atomic tactic
(like "eauto", "firstorder", "discriminate", ...), the code was
correct only when a rule of the form `TACTIC EXTEND ... [ "foo" -> ...] END'
was given (where "foo" has no arguments in the rule) but not when a rule
of the form `TACTIC EXTEND ... [ "foo" tactic_opt(p) -> ...] END' was given
(where "foo" had an optional argument in the rule). In particular,
"firstorder" was in this case.
More generally, if, for an extra argument able to parse the empty string, a rule
`TACTIC EXTEND ... [ "foo" my_special_extra_arg(p) -> ...] END' was given,
then "foo" was not recognized as parseable as an atomic string (this
happened e.g. for "eauto"). This is now also fixed.
There was also another bug when the internal name of tactic was not
the same as the user-level name of the tactic. This is the reason why
"congruence" was not recognized when given as argument of an ltac (its
internal name is "cc").
Incidentally removed the redundant last line in the parsing rule for
"firstorder".
