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
