Removes optional argument [access] from [as_zone].

Adds function [as_zone_result] that returns a zone result, without converting
error cases.

Changes the Inout plugin accordingly.

Removes unused declarations in plugins registration files.

Type [cacheable] is now defined in Eval.
Type [call_result] is defined in Builtins.
Changes the type of callbacks Db.Call_Type_Value_Callbacks.

this is a generalization of `check` vs. `assert` to other annotations. Not all
annotations are relevant though. Currently, there are more annotation nodes in
the AST that can have a flag `{ tp_only_check }` than was deemed useful in
pub/frama-c#25, but said flag can in fact safely be ignored. Moreover, this
commit only add this flag in the AST, but provides no further mean to set it to
true except for the original `check` keyword (i.e. on `AAssert`). The parser
and the behavior of the plugins that can handle the flag will be updated in
subsequent commits

Handles \exit_status exactly as \result.

Fixes a performance issue.

- 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.

Initialized const variables should be included as outputs of the function.

(blind make headers from specifications)

- 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.
