The current implementation was still using continuation passing-style, and
furthermore was triggering a focus on the goals. We take advantage of the
tactic features instead.

Note: I removed what seemed to be dead code in recdef.ml (local_assum
and local_def introduced with econstr branch), assuming that this is
what should be done.

Today, both modes are controlled by a single flag, however this is a
bit misleading as is_silent really means "quiet", that is to say `coqc
-q` whereas "verbose" is Coq normal operation.
We also restore proper behavior of goal printing in coqtop on quiet
mode, thanks to @Matafou for the report.

We remove `edit_id` from the STM. In PIDE they serve a different
purpose, however in Coq they were of limited utility and required many
special cases all around the code.
Indeed, parsing is not an asynchronous operation in Coq, thus having
feedback about parsing didn't make much sense. All clients indeed
ignore such feedback and handle parsing in a synchronous way.
XML protocol clients are unaffected, they rely on the instead on the
Fail value.
This commit supersedes PR#203.

We use heaps instead of continuously adding elements to an ordered list,
which was quadratic in the worst case.
As a byproduct, this solves bug #5359, which was due to a stack overflow on
big lists.

Several cleanups were performed.
1. Removal of dead code lurking around.
2. Removal of global variables used to pass arguments to functions, as well as
unnecessary mutable state here and there. We rely on state-passing and
encapsulated mutable state.
3. Removal of crazy reference manipulation and its replacement with proper list
handling, as well as cleaning up the source and taking advantage of invariants.
This should solve algorithmic limitations of the previous code.
4. Opacification of some structures to have a clearer idea of the code
requirements.
5. Cleaning of debug printing functions. We thunk the computation of the
debugging data, whose computation can be costly for no reason, and we rely
on Feedback-based interaction instead of Printf-debugging.

We remove the camlp4 compatibility layer, and try to clean up
most structures. `parsing/compat` is gone.
We added some documentation to the lexer/parser interfaces that are
often obscured by module includes.

Getting a key only needs to observe the root of a term. This hotspot was
observed in HoTT.

The transition has been done a bit brutally. I think we can still save a
lot of useless normalizations here and there by providing the right API
in EConstr. Nonetheless, this is a first step.

|
|
For now we only normalize sorts, and we leave instances for the next
commit.

This is a patch fulfilling the relevant remark of Maxime that an
explicit information at the ML type level would be better than "cast
surgery" to carry the optional type of a let-in.
There are a very few semantic changes.
- a "(x:t:=c)" in a block of binders is now written in the more
standard way "(x:=c:t)"
- in notations, the type of a let-in is not displayed if not
explicitly asked so.
See discussion at PR #417 for more information.

This is a bit long, but it is to keep a symmetry with constr_expr.

Deprecating abstract_constr_expr in favor of mkCLambdaN,
prod_constr_expr in favor of mkCProdN.
Note: They did not do exactly the same, the first ones were
interpreting "(x y z:_)" as "(x:_) (y:_) (z:_)" while the second ones
were preserving the original sharing of the type, what I think is the
correct thing to do.
So, there is also a "fix" of semantic here.

This reverts commit 6d2802075606dcddb02dd13cbaf38ff76f8bf242, which is
an 8.6 only commit.

We make apparent in the API that the implicit tactic is set or not. This was
costing a lot in Pretyping for no useful reason, as it is almost always unset
and the default implementation was just failing immediately.
|
|
All functions where actually called with the second argument of the pending
problem being the current evar map. We simply remove this useless and
error-prone second component.
