This was meant to happen but did not previously happen. It is not
ideal to do it now but better do it while we still can.
In short, this removes one half of the variables API (keeps
constants as they are) and repurposes the API to be only for
constants. This is also better for consistency to match errors.
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.
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.
Nothing parses yet, and no API is exposed. Also, move the remaining instances of file
inside of existing structures to Eolian_Object and parse basename only once.
