Subject: library/opaqueTables: enable their use in interactive mode

Before this patch opaque tables were only growing, making them unusable
in interactive mode (leak on Undo).

With this patch the opaque tables are functional and part of the env.
I.e. a constant_body can point to the proof term in 2 ways:
  1) directly (before the constant is discharged)
  2) indirectly, via an int, that is mapped by the opaque table to
     the proof term.
This is now consistent in batch/interactive mode

This is step 0 to make an interactive coqtop able to dump a .vo/.vi
