Also replace direct accesses into the type structure to get the return
type of a function with the same function.

Use it to retrieve statements contained in interface types.

Use it for retrieving the parent interface for interfaces.

Use it for retrieving the type that a pointer refers to.

Use it whenever retrieving the element type of an array.

Split out the defining of coclass types in the parser into a function.

It can trivially be derived from the type field now.

widl: Move creation of module type into a separate function, type_new_module and give it a special FC type.

Make duptype static and rename alias to type_new_alias.

Use type_is_alias to replace cumbersome "type->kind == TKIND_ALIAS" expressions.
Use type_get_real_type to simplify some code.

Store array type properties in the details union to save a bit of
memory and to make the general properties more obvious.

When the character or paragraph format is changed the paragraph that
is changed is already marked to be rewrapped, so ME_MarkAllForWrapping
shouldn't be called.  Since ME_RewrapRepaint uses this function, it
shouldn't be called in these circumstances, since rewrapping all the
text can cause noticable delays when working with a lot of text.

A common case for richedit controls are that a large amount of text is
set initially with word wrap enabled.  This causes the initially
wrapping of the text, which also calculates the text length.  After
this the vertical scrollbar will be shown, which causes the text to be
rewrapped again.  After this there are two redundant rewraps that are
done which this patch eliminates.

Pass parameters on the stack instead of retrieving them from the code
stream; this ensures that the code contains only valid instructions.

Also assume that all register functions are stdcall.
