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).

Some functions from pretyping/typing.ml and their derivatives were potential
source of evarmap leaks, as they dropped their resulting evarmap. This commit
clarifies the situation by renaming them according to a unsafe_* scheme. Their
sound variant is likewise renamed to their old name. The following renamings
were made.
- Typing.type_of -> unsafe_type_of
- Typing.e_type_of -> type_of
- A new e_type_of function that matches the e_ prefix policy
- Tacmach.pf_type_of -> pf_unsafe_type_of
- A new safe pf_type_of function.
All uses of unsafe_* functions should be eventually eliminated.

Since error messages are ultimately passed to Format, which has its own
buffers for concatenating strings, using concatenation for preparing error
messages just doubles the workload and increases memory pressure.

We provide an eliminator ensuring that the AST will be used to build a tactic,
so that we can stuff arbitrary things inside. An escape function is also provided
for backward compatibility.

This patch allows Coq terms to be extracted into the widely used JSON
format. This is useful in at least two cases:
- One might want to manipulate Coq values outside of Coq, but without
being forced to use one of the three existing extraction languages
(OCaml, Haskell, or Scheme), and without having to compile Coq's
extracted result. This is especially useful when a Coq evaluation
produces some data structure that needs to be moved out of Coq.
Having to invoke an OCaml/Haskell/Scheme compiler just to get a
data structure out of Coq is somewhat awkward.
- One might want to experiment with extracting Coq code into other
languages (Go, Javascript, etc), without having to write the whole
extraction logic in OCaml and recompile Coq's extraction plugin
each time. This makes it easy to quickly prototype extraction
in any language, without having to build Coq from source.
Extraction to JSON is implemented by adding the JSON "pseudo-language"
to the extraction facility. Thus, one can extract the JSON encoding
of a single term using:
Extraction Language JSON.
Extraction qualid.
and extract an entire Coq library "ident" into "ident.json" using:
Extraction Language JSON.
Extraction Library ident.

The extraction machinery has specialized support for extracting [ascii]
characters into native characters in the target language, as opposed
to using an explicit constructor from 8 boolean bits. This works by
hard-coding the name of the character type in the target language.
Unfortunately, the hard-coded type for Haskell was "Char", not the
fully-qualified "Prelude.Char". As a result, it was impossible to
extract characters into Haskell without getting type errors about "Char".
This patch changes this hard-coded name to "Prelude.Char".

Commit 84c2433a introduced the Any type alias as the Haskell extracted
version of MiniML's Tunknown. However, the code to define the Any
type alias was generated conditional on usf.magic. As it turns out,
sometimes Tunknown appears even if usf.magic is false (i.e., even if
MLmagic does not appear anywhere in the AST). This produced Haskell
code that would not compile; e.g.:
% coqtop
Coq < Extraction Language Haskell.
Coq < Extraction Library Datatypes.
The file Datatypes.hs has been created by extraction.
% ghc Datatypes.hs
[1 of 1] Compiling Datatypes ( Datatypes.hs, Datatypes.o )
Datatypes.hs:261:17: Not in scope: type constructor or class `Any'
Datatypes.hs:261:24: Not in scope: type constructor or class `Any'
The fix is straightforward: produce the code that defines the Any type
alias if usf.tunknown is true.

So that the commands are assigned the appropriate status of syntax-changing or not, as well as the proof mode they are setting.

It will not work in CoqIDE though, which handles printing its own way. It's a general remark that we have many ways of printing things in Coq and we should look for a unified structured framework to be shared between interfaces.

I had previously mistakenly enforced the property that after solving every goal in a block, unfocusing was performed automatically until one goal is in focus. This is not how the declarative mode is supposed to behave. Rather every focus must be explicitely unfocused by a closing command.
This hit a few bad interaction with the pure representation of proof introduced for the asynchronous processing.
Some of the invariants seem fragile, so this minimally disruptive solution is probably not long-term. In particular since each block uses the same focus kind, an `end <block>` may close another block than intended if the number of unfocussing command executed is not the right one.
