testsuite/Makefile.toplevel: make terminal DUMB by default (tests rely on this)

Currently it is not equivalent to do:
  cd testsuite; make one DIR=tests/$foo
and
  cd testsuite/tests/$foo; make
because the latter will not set TERM=dumb and toplevel tests will use
nice escape-code location highlighting instead of ASCII-made squiggly
lines, which breaks the tests.

ocamlbuild: add an explicit "infer" tag for menhir (Patch by Hugo Heuzard)

This allows to prevent the --infer option from being passed to Menhir
by using the negative tag -infer.

rewrite the printing of Lazy values in toplevel/genprintval.ml

The code previously used Lazy.is_val to know whether the value was
already-evaluated (and, in this case, Lazy.force to extract this value
and print it more precisely). But it lies inside a functor that is
instantiated over different implementations of Obj, while
Lazy.{is_val,force} force the use of the Obj module of the standard
library. This could cause segfaults when this code is called from the
debugger, which instantiates it with a different Obj module talking
over a socket.

ocamldebug: fix printing of variables of lazy type

"print a" in ocamldebug when a is a forced lazy value segfaults on all
OCaml versions I tested it on. This comes from the fact that the
debugcomm.ml re-implementation of the Obj module (talking over the
debugging socket) implements Obj.tag without special-casing integers
(that is, testing is_block first), and always assumes its input is
a block.
