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.

Each regular class can now have a section called 'composite',
which can contain interfaces and interfaces only. This defines
a list of interfaces that are allowed to be unimplemented on the
class, as it is assumed the class will be composited with some
other class implementing those interfaces.
Only regular classes can have this, as only regular classes can
be instantiated.
It will also be necessary to check whether the classes in the
section appear somewhere within the inheritance tree. For now,
this testing is not being done.
Example of usage:
composite {
Some.Magic.Interface;
Another.Magic.Interface;
}
directly in the class body.
The checks are only done for regular classes. It's also disabled
by default as too many methods would be unimplemented.
Use EOLIAN_CLASS_UNIMPLEMENTED_WARN=1 to enable the errors.
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.
Most of the time you need to retrieve the class from the string
anyway, so remove this relic of old Eolian and gain some small
performance benefits and extra convenience.
Subtly breaks API but everything should be updated.
Previously events used to use class name as a prefix and ignored eo_prefix
when specified. This is no longer the case. Events follow eo_prefix by default
now. In order to get around this for classes where this is undesirable, a new
field event_prefix was added which takes priority over eo_prefix. If neither
is specified, class name is used like previously.

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.
This commit also does several side (related) changes. Particularly, it updates
the Eolian C generator to use the new API, it adds missing expr types (null, char)
and masks, updates the API dealing with default return values to use expressions
instead of strings and does several fixes (mainly in lexer) around the place.
It also disallows single quoted strings as those are reserved for characters.
For this purpose, several other changes were made. There can now only be 1 class per file
and the class name has to match the file name. Also, I replaced the list of classes with
a hash, allowing for fast indexing (crucial for parser performance - otherwise it was
very slow).
This also adds a new API, eolian_type_class_get.
