[Eva] Base: rewrites is_valid_offset and valid_offset

[Libc] remove unnecessary include

See merge request frama-c/frama-c!2213

The extraneous include prevents gzip from compiling.

It is now invalid to read/write an empty struct in an Invalid base (such as the
null base).

- shares and moves the functions [reduce_offset_by_validity] of Locations and
  Precise_locs into base.ml.
- replaces the boolean argument ~for_writing into the new type access, that
  represents Read, Write or No_access. Without any access, offsets must point
  into or just beyond the base validity.
- fixes the support of accesses of size 0: they are now invalid:
  + in bases with Invalid validity;
  + one past a base validity unless the base ends with an empty struct.

If needed, this boolean could be computed by the callers of these functions via
Base.is_valid_offset.
In Base, do not export offset_is_in_validity, that was only used to compute
this boolean.

Since commit #8783731f and #28139960 this option is not needed anymore.
I updated LUncov (which was the only plugin using it) to remove it as well

Avoid alpha-conversion clashes

Closes #618

Do not use two distinct undo stacks for taking care of which symbols are in use
at a given program point. Let `Alpha` manages everything internally.
