This fixes cases such as missing const when having a @by_ref
return type. The const should not be avoided there because it
is not returning the whole type as const, just what the pointer
dereferences to.
This adds a new unified syntax for giving declarations C names.
Classes: class @c_name(Foo) Foo ...
Types: type @c_name(Foo) Foo: Bar ...
Structs: struct @c_name(Foo) Foo ...
and so on. Type instances properly inherit those. This also cleans
up some other parts of the source code.
Fixes T6716.
This is to prepare for type/class renaming support. This adds
the necessary API to retrieve C-specific names. Other refactoring
is necessary elsewhere for now.
This also renames the old API eolian_class_c_name_get to
eolian_class_c_macro_get to avoid conflict as well as clarify
the intention.
Summary:
This removes all Eolian API that deals with handling of legacy
code. It also removes the code using it in the generator as well
as bindings, but for now keeps generation of .eo.legacy.h types,
as there are still instances in our codebase where things are
otherwise broken. We can remove the rest once that is resolved.

This feature was kind of ill-conceived and never worked properly.
Since there isn't enough time to make it work right at this point
and there are no users of it in the API, remove it for now.
It might get added in the next release cycle, in a proper form.

This adds support for inlist structs, a special type of struct
that can only be used with inlists. This differs from regular
structs in a couple ways:
1) They are stored separately. Just like structs, enums, aliases
have their own storage, so do inlist structs.
2) They can't be @extern, nor they can be opaque.
3) They are their own type of typedecl.
4) When they contain only one field, this field must be a value
type always, cannot be a pointer.
Like regular structs, they can have arbitrary fields, and they
can have a pre-set free function via @free().
In C, the inlist structs will be generated exactly like ordinary
ones, except they will have EINA_INLIST before the first field.
Other binding generators can deal with them as they wish, for
example to provide high level interfaces to them.
This does not yet do the plumbing necessary to hook these into
the type system, nor it adds generator support.
@feature
This finally enables looking up things from the current unit
rather than from a backing storage in the Eolian state. This
also means that the benefits of having a unit system will
finally be visible.
This makes sure variables are stored as well as types within their
respective units. Also, declarations are now refcounted just like
any other Eolian object.
Eolian now properly merges all unit hashes (e.g. unit A has
children B and C, hashes of B and C are merged into A's hashes
in order to be able to look up B and C's contents via A) and
maintains a (potentially cyclic) children graph.
Not everything is yet added into all hashes, but at least the
building blocks are there.
As it is no longer necessary to pass unit when evaluating exprs,
it is not necessary to pass it here either. Convert all the APIs
to the new style and update all instances in our tree.
This disallows deeply nested pointers, you can only explicitly
ptr() on types that are strictly value types.
For a few cases where it was necessary to override this behavior,
you can use legacy(ptr(x)) as a temporary measure.
This is a new type representing a mutable string (no const).
Regular strings cannot be made mutable with @owned because
they might be hidden behind typedefs.
For example, aliases to ownable types are now also ownable,
which wasn't possible in the previous version, where you could
only own actual expanded ownable types.
We don't need to keep this in eo files anymore because the APIs
using them are now fully in C. This also allows removal of the
event callback builtin from Eolian.
Adds two new type types, STATIC_ARRAY and TERMINATED_ARRAY. Static arrays are
only allowed as struct members right now - they translate to regular C static
arrays (allowing them elsewhere wouldn't be good, as C isn't very good at
working with the size information). Terminated arrays are basically sequences
of data terminated at the end. The base type of static arrays can be any type
that is not marked ref (explicit ref may get allowed later). The base type of
terminated arrays has the same restriction plus that it has to be either
implicitly reference type (i.e. translating to pointer in C), integer type
or a character. In case of ref types, the terminator is NULL. In case of
integer types, the terminator is a zero. In case of character types, the
terminator is also a zero (null terminator like C strings).
