This generates additional macros to help keeping implementation simple,
guarded with WIDL_using ifdefs, like this:
#ifdef WIDL_using_Windows_Foo
#define IFooVtbl __x_ABI_CWindows_CFoo_CIFooVtbl
#define IFoo __x_ABI_CWindows_CFoo_CIFoo
#define IFoo_DoFoo __x_ABI_CWindows_CFoo_CIFoo_DoFoo
#endif /* WIDL_using_Windows_Foo */
Implementation files can define the desired WIDL_using preprocessor
macros before including the header, and then implement or use the
interface methods with the simple non-prefixed names instead.

MinGW g++ requires initialized selectany to have extern linkage.
Also, because of the various ways WCHAR may be defined, using an array
initializer is the simplest way to support all cases.

This allows parameterized interfaces to be instanciated in declare
blocks, in the same way MIDL does, generating a new interface to the
header from the parameterized type template, replacing its parameters
with the given types.

And add IVectorView<T> and IIterator<T> parameterized interfaces to
windows.foundation.idl for illustration and future use. They won't
generate any additional code until they are fully specialized.
This is a WIDL-specific feature, but MIDL has some magic knowledge of
these Windows.Foundation.Collections interface templates, and we need a
way to instruct WIDL about them too.
Having these interfaces declared in the IDL, guarded with __WIDL__ ifdef
is easier and more flexible than re-creating the types by hand in WIDL
source.

For types under a non-global namespace.
MIDL generates prefixed mangled name for every use of enum, struct and
union types. When the types are in the global namespace, the typedef
name is used instead.

This function lacks a declaration in header.h and isn't used
outside of this source file.
This fixes warnings about missing a prototype, when built as part
of mingw-w64-tools (where it is built with -Wmissing-prototypes).

This mainly affects 64-bit winelib applications, and potentially mingw-w64
usage of the Wine headers. As explained in commit
fabfa59aea, MSVC returns aggregates through an
implicit parameter immediately after the this/interface pointer. GCC's
"ms_abi" attribute is supposed to match this, but unfortunately current
versions of g++ (confirmed up to at least g++ 6.3) place the implicit return
pointer before the this/interface pointer. See also
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52792.
This commit takes an approach similar to the earlier commit
fabfa59aea5c5b3201142382038beb3e76cb7567: For ABI compatibility the return
pointer is listed as an explicit parameter in the vtbl entry, while an inline
helper is provided for source code compatibility.
