According to the old new thing[0], we should use the instance handle
of the GDK/GTK DLL when registering GDK-specific types in the system.
Using the instance handle for the whole application in these circumstances
is not an error, but can potentially clash with the types registered
by the application itself.
Also, extract window class icons from the GDK/GTK DLL, not from the
application executable.

The argument is eventually passed to g_conv(), so it should
be the charset, not the mime/type. Without this change the
contentype converter will fail to convert UTF-8 strings to, say,
CP-1251 later on.
Unconditionally putting 'gdkwayland_inc' in src_dir argument of gtkdoc
call tells gtkdoc-scan to scan source files in a non-existent build
directory, gdk/wayland. To avoid causing build failure when a specific
backend is disabled, we should include directories conditionally.
Otherwise gcc complains when we use these as arguments to g_new() on
32bit architectures with:

check_dir_mtime() is called by ftw() and is given
the real stat struct, not its glib version (which may
or may not be the same as "struct stat").
This is irrelevant for MSVC (it has no ftw()) and
works correctly for MinGW-w64 (which declares stat
structures correctly). If mingw.org complains, add
a special ifdef for it later.
It's quite old, but mostly harmless (both "message == WM_KEYUP"
and "message = WM_KEYUP" evaluate to not-FALSE, and message
value is not used after that line).
