The interface was ready for this API but it was not provided.
So implement this, using a thread that calls the sync API for now.
Add tests.
Helps with: GNOME/glib#157
`GSocketClient` chains its internal `GCancellable` objects to ones
provided by the caller in two places using `g_cancellable_connect()`.
However, it never calls `g_cancellable_disconnect()`, instead relying
(incorrectly) on the `GCancellable` provided by the caller being
short-lived.
In the (valid) situation where a caller reuses one `GCancellable` for
multiple socket client calls, or for calls across multiple socket
clients, this will cause the internal `GCancellable` objects from those
`GSocketClient`s to accumulate, with one reference left each (which is
the reference from the `g_cancellable_connect()` closure).
These `GCancellable` instances aren’t technically leaked, as they will
all be freed when the caller’s `GCancellable` is disposed, but they are
no longer useful and there is no bound on the number of them which will
hang around.
For a program doing a lot of socket operations, this still-reachable
memory usage can become significant.
Fix the problem by adding paired `g_cancellable_disconnect()` calls.
It’s not possible to add a unit test as we can’t measure still-reachable
memory growth before the end of a unit test when everything has to be
freed.

This prevents `-Wunused-function` warnings on platforms which don’t have
`HAVE_OPTIONAL_FLAGS` defined.

g_object_new_with_custom_constructor needs to handle
freezing notifications in the same way as
g_object_new_internal.
Fixing a bug pointed out by Christian Hergert.
The corner-case we are handling here is that
we don't freeze the notify queue in g_object_init
(because there's no custom ->notify vfunc, but
then we gain a notify handler during instance
init, and instance init also triggers a
notification. Handle this by jit freezing
notification in g_object_notify_by_spec_internal.
Note that this is bad code - instance init really
shouldn't be doing things like this.
Testcase included.
Fixes: #2665
We need to match the conditions in g_object_init
for when we already have a freeze. Without that,
we underflow the freeze count and trigger a
warning.
Fixes: #2666
Beef up the singleton testcase to reproduce a
freeze count underflow when setting properties
at construction time, with a custom constructor.

These are deprecated, but it’s easy enough to test them anyway. This
bumps up code coverage a bit and hopefully ensures we don’t accidentally
regress on them in future.

At the moment these tests basically just ensure that the program’s
compiled properly and doesn’t crash on startup. They don’t check
functionality very deeply.
But they’re a start.

This has been documented in `man gobject-query` for a long time, but

This makes the output a lot nicer to read:
```
│
├void
│
├GInterface
│ │
│ └GTypePlugin
│
├gchar
⋮
```
rather than
```
|
`void
|
`GInterface
|
`GTypePlugin
|
`gchar
⋮
```
It includes a change to correctly use vertical tees at the top level by
correctly setting the sibling node rather than always setting it to
zero.

This doesn’t change the tests’ behaviour, but moves them to a slightly
more logical location.
They are still not installed or run by default.
