* w32-util.c: Include ath.h
	(HAVE_ALLOW_SET_FOREGROUND_WINDOW) [!HAVE_W32CE_SYSTEM]: Define
	it.
	(RTLD_LAZY, dlopen, dlsym,
	dlclose) [!HAVE_ALLOW_SET_FORGROUND_WINDOW]: Don't define anymore.
	(_gpgme_allow_set_foreground_window) [!HAVE_ALLOW_SET_FOREGROUND_WINDOW]:
	Make it a stub.
	(read_w32_registry_string): Use FooA variants of Windows functions
	instead of Foo (which dispatches depending on UNICODE).
	[!HAVE_W32CE_SYSTEM]: Don't check environment.
	(w32_shgetfolderpath): Remove.
	(find_program_at_standard_place): Call
	SHGetSpecialFolderPath (which is available on all Windows systems
	and also Windows CE).
	(mkstemp): Use ath_self instead of getpid.
	(_gpgme_mkstemp): Use GetTempPathA instead of GetTempPath.
