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).

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.

This changes the checks in eolian type API so that you can use the various
type funcs on incompatible types, getting a NULL in return; this allows
simplified generator logic, with error handling done on generator side,
without getting annoying messages from the Eolian lib.
This adds new APIs that deal with the new documentation syntax
provided by Eolian. The old doc comment APIs are considered
deprecated from now on and will be removed.
