Add an implementation of non-thread-emulated async close of a GIOStream
if either of the underlying stream objects support it.
This prevents us from calling close() functions from another thread on
an object that may not be expecting that. It also allows us to skip the
thread entirely in case our objects support a pure async close.

It’s not enough to close a connection by calling g_input_stream_close()
and g_output_stream_close() on its two substreams: to close the
underlying socket, one must use g_io_stream_close(). Document that.

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
Rather than doing a two step first-check-the-GAsyncResult-subtype-then-
check-the-tag, add a GAsyncResult-level method so that you can do them
both at once, simplifying the code for "short-circuit" async return
values where the vmethod never gets called.

Finish deprecating the "handle GSimpleAsyncResult errors in the
wrapper function" idiom (and protect against future GSimpleAsyncResult
deprecation warnings) by adding a "legacy" GAsyncResult method
to do it in those classes/methods where it had been traditionally
done.
(This applies only to wrapper methods; in cases where an _async
vmethod explicitly uses GSimpleAsyncResult, its corresponding _finish
vmethod still uses g_simple_async_result_propagate_error.)

Originally, the standard idiom with GSimpleAsyncResult was to handle
all errors in the _finish wrapper function, so that vmethods only had
to deal with successful results. But this means that chaining up to a
parent _finish vmethod won't work correctly. Fix this by also checking
for errors in all the relevant vmethods. (We have to redundantly check
in both the vmethod and the wrapper to preserve compatibility.)
