Revised infrastructure for lazy loading of opaque proofs

 Get rid of the LightenLibrary hack : no more last-minute
 collect of opaque terms and Obj.magic tricks. Instead, we
 make coqc accumulate the opaque terms as soon as constant_bodies
 are created outside sections. In these cases, the opaque
 terms are placed in a special table, and some (DirPath.t * int)
 are used as indexes in constant_body. In an interactive session,
 the local opaque terms stay directly stored in the constant_body.

 The structure of .vo file stays similar : magic number, regular
 library structure, digest of the first part, array of opaque terms.
 In addition, we now have a final checksum for checking the
 integrity of the whole .vo file. The other difference is that
 lazy_constr aren't changed into int indexes in .vo files, but are
 now coded as (substitution list * DirPath.t * int). In particular
 this approach allows to refer to opaque terms from another
 library. This (and accumulating substitutions in lazy_constr)
 seems to greatly help decreasing the size of opaque tables :
 -20% of vo size on the standard library :-). The compilation times
 are slightly better, but that can be statistic noise.

 The -force-load-proofs isn't active anymore : it behaves now
 just like -lazy-load-proofs. The -dont-load-proofs mode has
 slightly changed : opaque terms aren't seen as axioms anymore,
 but accessing their bodies will raise an error.

 Btw, API change : Declareops.body_of_constant now produces directly
 a constr option instead of a constr_substituted option
