You can now declare errors like this:
error Foo = "message"; [[documentation]]
Then you can use them as types like this:
foo {
return: error(Error1, Error2, ...);
}
They have a separate type category and storage. They are checked
for redefinitions the same as anything else though. This does
not add any generator support nor it adds any advanced checking.

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.

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.
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.
These types are of questionable value and the API was not entirely
thought out - remove for now, and if a legitimate use is found
later, they may be readded (with a better API), but typically it
seems best to redesign the bad APIs around safe containers...
First steps toward explicit function pointer support in eolian.
To declare a function pointer type, use the following syntax, similar to
a regular eolian method declaration.
function FunctionName {
params {
...
}
return: Return type
}
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).
@feature
Inner type can now be retrieved as a base type of the type.
If the type has two inner types or more, there is a new API that allows you to
get the second inner type by calling it on the first one (same would apply to
getting third via second etc.).
This API is simpler to use and doesn't require an iterator.
It's now possible to mark struct fields and function params as "references",
which causes them to become pointers in C (in bindings, they become whatever
is necessary). They're not a part of the type and are much more restricted
than pointers, allowing bindings to be easier. This system will be gradually
utilized and expanded as required.
