st/bin: Delegate child allocation to layout manager
Since commit ed3b8d093e16, the actor's single-child policy is
enforced even when using the generic add/remove_child() methods.
This makes it possible to follow GTK/AdwBin's lead and replace
out custom child allocation with a BinLayout, without changing
the actor's semantics in a fundamental way.
However this does change slightly how the child is allocated, as
it now only expands according to its expand properties, not when
the alignment is set to FILL.
Even after the preparations in the previous commit, some fallout
is still likely, but it will be easy to address, and the cleanup
is significant enough to justify it.

Right now, St.Bin ignores the child's expand properties, and

dbusService: Exempt org.gnome.Shell from sender tracking
If an interface has any signals, we don't want to auto-shutdown
while a caller is still connected to a signal.
Unfortunately we can't tell whether there are any signal connections,
so we track all callers instead, and keep the service alive while
any of them is still on the bus.
For services that we call from gnome-shell itself - like screencasts
or extensions - this has the unintended side effect of effectively
disabling auto-shutdown.
Address this by exempting the org.gnome.Shell name from sender
tracking.
Services that we expect to keep running for the lifetime of the
shell already disable auto-shutdown, so the only downside is a
small startup delay to resolve the well-known shell name.

happens to satisfy these conditions by chance which then leads to the
class string containing some of this unrelated memory. Or it might lead
to a segfault.

tools: Remove outdated jhbuild setup script
As useful as the custom jhbuild setup was at the time, it has been
superseded by jhbuild proper (which gained the ability to install
system dependencies since) or alternatives like containers.
Given that the script hasn't been meaningfully updated for almost
10 years, its list of dependencies is hopelessly outdated, and it's
therefore more likely to confuse newcomers than being of actual
help.
As much as I have fond memories of the script when starting out,
it's finally time to retire.
Wrapping the gnome-shell call with `dbus-run-session` is *mostly*
enough for testing, but not quite.
When running without gnome-session, the wayland display is not
propagated to the D-Bus daemon, so any app that is D-Bus activated
still opens in the host session.
This can be worked around by using a specific wayland-display name
and exporting it to the `dbus-run-session` environment up-front.
At this point the invocation is finicky enough to justify another
convenience script. This also gives us a place to expose some
useful features for testing, like forcing a right-to-left layout
or simulating the greeter.
We don't require any build steps other than the standard meson
commands, but entering a toolbox and running 2-3 meson commands
still adds some friction.
Add a small convencience script that
- finds the toplevel source directory (similar to `jhbuild make`)
- enters the speficied toolbox (or the configured default)
- automatically picks a build directory based on the toolbox name
- builds and installs the project to /usr (inside the toolbox)
It also allows specifying meson -D options to change the build
configuration, and to optionally run `meson dist`.
Setting up more than one gnome-shell toolbox is uncommon, and users
shouldn't have to specify --set-default for other tools to pick the
right default.
It would be possible to detect the number of containers that were
created from the shell toolbox image, but the far easier option is
to just set up the first container as default.

would fit into the allocated size or -1 (i.e. no limit) if there are no
children. So for the initial search there is no limit and in the app
search all matching apps get added as possible results, which due to the
search term being only a single character is almost all installed apps.
This now causes allocation to be run for all these results, despite the
vast majority of them never being visible, which on slower machines can
cause noticeable delays before the search results are displayed.
This now adds the ability for search providers to specify a maximum
