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
Eolian now separates 'parent' and 'extensions'. For regular
classes, parent is the first item in the inherits list and
extesions is the rest. For interfaces and mixins, parent is
NULL and extends is the inherits list.
The reason for this is the separation of them in syntax in near
future. It also slightly changes the behavior; since for interfaces
and mixins, parent is always NULL now, you can freely inherit from
all types of classes without needing to manually put an interface
type as the first item of the inherits list.
It is not necessary to check entire classes/typedecls/variables
when referenced, as that also checks their contents and adds
false negatives. It is enough to simply add their own unit
as a 'used' dependency and let the system do the work, besides
for actual declarations in the checked file.
