[Eva] Checks consistency between the builtin type and the replaced C function

Closes #671

See merge request frama-c/frama-c!2499

This annotation sets the maximum number of subdivisions in the evaluation
of expressions at a given statement.

Overrides the global option -eva-subdivide-non-linear for the given functions.

Prerequisite for new options or annotations to configure more finely
the subdivisions.
In partition.ml, the subdivisions are disabled.
Other files always use the default value of subdivisions.

This new parameter [subdivnb] is optional, and the value of the global option
-eva-subdivide-non-linear is used by default.

The maximal number of subdivisions is a new field of the context record for the
forward evaluation functions, as it is also used when calling the oracle.

The valuation is no longer optional, as it should always be explicitly given for
efficiency reasons.
The order between arguments has also been made uniform (context, then valuation,
then other arguments).

All forward evaluation functions use the same arguments without modifying them:
- the current state of the abstract domain;
- the remaining fuel;
- the oracle.
These arguments are now gathered into a context, which will facilitate the
introduction of new similar arguments.

Removes the reference for the oracle.

New function Builtins.is_builtin_overridden that indicates whether a function
is replaced by a builtin.
This function remains correct after loading the result of a previous analysis,
and can thus be used by other plugins using Eva's results.
Thus, Db.Value.use_spec_instead_of_definition now uses this function.

The builtin __fc_vla_alloc is used for the generated function __builtin_alloca,
whose name is indeed "__fc_vla_alloc".

Replaced by the warning category builtins:override for more than a year.

This function links the kernel functions to their builtins for a given analysis.
Checks that the builtin replacing a function has a compatible type and a
specification. These requirements are not checked each time a builtin is used.

The type of a builtin is now a function "unit -> typ" applied when the analysis
starts, allowing builtins to use types defined from the machdep, such as size_t.

If provided, the expected type is compared to the actual type of the C function
to be replaced by the builtin. In case of inconsistency, the builtin is not used
and a warning is emitted.
