In all files, all occurrences of "[eva] done for function" have been replaced
by "[eva] Done for function".

On some loops allocating memory, the size of the allocated base can be
increased at each iteration without widening, thus preventing the convergence
of the analysis.
In lmap, when the widening has no effect, we widen the size of such allocated
bases to avoid such issues.

- always remove FC's internal attribute everywhere before deciding whether
  a cast is needed.
- ACSL and C decisions to cast are similar
- only unroll type for checking equality. If a cast is needed, keep
  typedef (if any) as target

- Fix Value/Value#5
- Fix Value/Value#14

Some case studies (e.g. dyad) use some ugly casts from fd_set_t which lead
to the analysis stopping too early.
Changing the representation of fd_set_t should also help it better conform to
the standard (since a fd_set_t should be able to hold FD_SETSIZE elements).

[Ptests] preserve LOG after STDOPT directive

This is absolutely not a sneaky attempt to relaunch a build (now that OCI seems
in better shape) pushing a nearly empty commit.
