Accepted forward declared structs do not get a type in Go

[CtrlZvi]

Forward declared (incomplete) structs will never have a type created for them in Go. This leads to generated code that cannot be compiled. I think it makes sense to generate them as a new named type with underlying type of the C.struct_* type would be a good way to handle it.

Example inputs that show the problem:

struct foo;

struct foo* bar();

// To define bar for test purposes
#include "test.h"

struct foo* bar() {
    return 0;
}

GENERATOR:
  PackageName: test
  Includes: ["test.h"]

PARSER:
  SourcesPaths: ["test.h"]

TRANSLATOR:
    MemTips:
      - {target: ^foo$, self: raw}
    Rules:
      type:
        - {action: accept, from: ^foo$}
      function:
        - {action: accept, from: ^bar$}

Hm, this is strange, as I remember I actually complete the initial declaration once the body of the struct is available later.

See for example https://github.com/xlab/alac-go/blob/master/alac/alac.h#L6 is this the same case?

Not quite. In this case the struct is never completed in the headers. It's only ever forward declared.
