While these assertions look right at the first glance,
they actually crash the program. That's because GObject
insists on initializing all construct-only properties
to their default values, which results in
g_win32_registry_key_set_property() being called multiple
times with NULL string, once for each unset property.
If "path" is actually set by the caller, a subsequent
call to set "path-utf16" to NULL will fail an assertion,
since absolute_path is already non-NULL.
With assertions moved the set-to-NULL calls bail out before
an assertion is made.
An extra argument to g_win32_registry_key_get_value_w() and
g_win32_registry_key_get_value() indicates that RegLoadMUIStringW()
should be used instead of RegQueryValueExW(). It only works on
strings, and automatically resolves resource strings (the ones
that start with "@").
The extra argument is needed to find resource DLLs that are only
specified by their relative name.
There are a few places where commit 18a33f72 replaced valid (nullable)
(optional) annotations with just (optional). That has a different
meaning.
(nullable) (optional) can only be applied to gpointer* parameters, and
means that both the gpointer* and returned gpointer can be NULL. i.e.
The caller can pass in NULL to ignore the return value; and the returned
value can be NULL.
(optional) can be applied to anything* parameters, and means that the
anything* can be NULL. i.e. The caller can pass in NULL to ignore the
return value. The return value cannot be NULL.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
* Only check __OBJECT_ATTRIBUTES_DEFINED and __UNICODE_STRING_DEFINED
on MinGW (MSVC doesn't have these)
* MSVC: disable:4005 when including windows.h and ntstatus.h
* Move NTAPI cconv into the parens with the NtQueryKeyFunc
* Fix return values in some functions
