Clean-up of proof_type.ml : no more Nested nor abstract_tactic_box

 Nested was never constructed, while the notion of abstract_tactic_box
 is obsolete (cf. Refiner.abstract_tactic).

Clean-up : removal of Proof_type.tactic_expr

 This instance of gen_tactic_expr was used only to decorate
 tactics via Refiner.abstract_tactics and alii, but these
 expressions are now ignored by the new proof-engine (no "info"...).

Adapt pieces of code needing -rectypes

 * in Matching and Tacinterp : ad-hoc types for encoding matching
   result and "next" continuation

 * in Class_tactics, occurrences of types such as
    "type t = (foo * (unit->t) option"
   have been specialized to something like
     type t = TNone | TSome of foo * (unit -> t)

remove dumptree.ml4

 This file was providing the "Dump Tree" command to display
 the state of a proof in XML. This command has been broken since
 the integration of Arnaud's proof engine. Nobody cared enough
 to adapt this to the new framework, moreover the trend is
 rather now to use the xml-base dialog mode of coqtop,
 so I simply remove this obsolete code.

Turn mltop.ml4 into a regular ocaml file

 The IFDEF's in mltop.ml4 were there to support platforms with
 a native ocaml compiler but no dynlink.cmxa, a situation that
 should be pretty rare in the Coq community nowadays (playing
 with coqtop on ARM, anyone ?). So we now refuse to build
 a native coqtop unless dynlink.cmxa exists (cf ./configure),
 and we explain how to create a dummy one if necessary
 (cf dev/dynlink.ml). This way, we can clean-up mltop.ml,
 and remove ugly special rules in Makefile and myocamlbuild

 NB: I checked that this shouldn't have any impact on Coq's
 debian packages on exotic architectures (arm, mips, ...),
 since apparently on these architectures no ocamlopt at all
 are shipped, and coq packages are already byte-only
