8b443c3556 gdelayedsettingsbackend: Fix applying after calling g_settings_reset()
`g_settings_reset()` changes the value of the setting to `NULL`;
`add_to_tree()` was not handling that correctly.

Add a unit test.

63abca2963 gsettings: Add missing changed() call to delayed settings backend
When resetting a key in the delayed settings backend,
g_settings_backend_changed() was not called to notify the backend of
the change.

698970f1f7 gsettingsbackend: a minor simplification
Change the order of the arguments on the (internal) keys_changed callback in
GSettingsListenerVTable.

This means that all functions in the table now fit the following signature:

  void (* f) (GObject             *target,
              GSettingsBackend    *backend,
              const gchar         *name_or_path,
              gpointer             origin_tag,
              const gchar * const *names);

allowing the possibility of arguments ignored at the end.

This allows us to simplify our dispatch-to-thread code in GSettingsBackend,
making it a bit less generic.

So far, this should be a straight refactor.

84a6e651c2 GSettingsBackend: add read_user_value() API
This will get the 'user' value from the database (ie: the one that the user has
control over).

Provide a default implementation that chains to ->read().  That will work for
all of our internal backends which don't have a concept of layering or
lockdown.

The delayed backend implments "user value" by returning anything that's
in the changeset (incuding an explicit NULL) or chaining up otherwise.

We will use this for g_settings_get_user_value().

54cc43630d Rename the generated private data getter function
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.

1361ec78cd GSettings: keep resets on loss of writability
Don't drop resets from a GDelayedSettingsBackend when the writability
changes.  Resets will always succeed, even against non-writable keys and
some people (gnome-screensaver) are using them in a way that they would
want them not to be forgotten.

0bd50b39eb Bug 623400 - acquire context before dispatching
For GSettings.

Use the functionality introduced in the last commit to simplify our
notify dispatching and increase the safety of doing so (by ensuring that
the context is acquired in the current thread for the duration of the
dispatch).

This closes bugs #623400 and #629849.

799e0242ae improve thread safety in GDelayedSettingsBackend
- hold a lock while accessing the tree of delayed values
  - use weak reference counts with the owner object to avoid doing
    g_object_notify on a dead object
  - dispatch the "has-unapplied" notify to the proper main context

61219e2640 GSettingsBackend: make signal dispatch threadsafe
This commit fixes up a few race conditions in the GSettingsBackend, mostly with
respect to change notifications occuring at the same time as the last reference
count on a GSettings is dropped.  With GDBus feeding us our incoming signals in
a separate thread, this is something that could easily happen.
