Update CHANGES, no evar_map is produced by pattern_of_constr anymore.

- Had to add a Sigma.to_evar_map
- Had to rework coqdep_common.ml{,i} and coqdep.ml

for reporting it.
A "cut" was not appropriately chained on the second goal but on both
goals, with the chaining on the first goal introducing noise.

Keep user-side information on the names used in instances of universe
polymorphic references and use them for printing.

Side effects are now an opaque data type, called private_constant, you can
only obtain from safe_typing. When add_constant is called on a
definition_entry that contains private constants, they are either
- inlined in the main proof term but not re-checked
- declared globally without re-checking them
As a safety measure, the opaque data type contains a pointer to the
revstruct (an internal field of safe_env that changes every time a new
constant is added), and such pointer is compared with the current value
store in safe_env when the private_constant is inlined. Only when the
comparison is successful the private_constant is not re-checked. Otherwise
else it is. In short, we accept into the kernel private constant only
when they arrive in the very same order and on top of the very same env
they arrived when we fist checked them.
Note: private_constants produced by workers never pass the safety
measure (the revstruct pointer is an Ephemeron). Sending back the
entire revstruct is possible but: 1. we lack a way to quickly compare
two revstructs, 2. it can be large.

Since the functions of this plugin exit by raising exceptions, globing
was never restarted. This prevented coqdoc from generating a proper
output whenever some feature of this plugin was used. There does not seem
to be any parsing of dynamic expressions, so pausing globing does not make
much sense in the first place.

This is not perfect though, some primitives are unsound, and some
higher-order API should use polymorphic functions so as not to depend
on a given level.

The evar_map's that are used to typecheck terms must now always be
initialized with the global universe graphs using Evd.from_env, so any
failure to initialize and thread evar_map's correctly results in errors.

The previous extraction of [Z.div] for Haskell did not properly handle
divide-by-zero. Fix it by introducing an explicit [if] statement in the
generated Haskell code.
Also, introduce a similar extraction rule for [Z.modulo], with the same
check for modulo-by-zero.

The previous extraction of [Nat.div] for Haskell did not properly handle
divide-by-zero. Fix it by introducing an explicit [if] statement in the
generated Haskell code.
Also, introduce a similar extraction rule for [Nat.modulo], with the same

Use expand projection to come back to the projection-as-constant encoding, dealing with parameters correctly.

This mirrors the existing extraction libraries for OCaml.
One wart: the extraction for [string] requires that the Haskell code
imports Data.Bits and Data.Char. Coq has no way to add extra import
statements to the extracted code. So we have to rely on the user to
somehow import these libraries (e.g., using the -pgmF ghc option).
