While we don't actually require a more recent version at build time,
we do need the latest stable version at runtime. There's no strong
reason for making that differentiation, so bump the requirement.

The browser plugin is crashy and broken; there are dozens of bugs filed
against it on Bugzilla and nobody is looking at them. Chrome and Firefox
have both dropped support for NPAPI plugins. Epiphany still has support,
but it's hidden behind a gsetting and all the UI to enable it has been
removed, so very few users would be able to figure out how to enable.
I've even previously considered blacklisting this plugin in the past due
to all the crashes.
Since this plugin has not actually worked in any browsers for a long
time now, time to delete it.

While the new per-desktop overrides in GIO are easier to use for
both developers and users, it is still inconvenient for everyone
who changed the defaults using the old overrides hack to lose
their settings. Address this by running a small script on startup
that migrates existing settings.

Depending on hardware and recorded volume level, turning up the speakers
to the maximum volume may not be enough and the user will want to amplify
the volume above 100%. Currently this requires opening the sound Settings
panel which gets cumbersome when required repeatedly.
To support this case better, allow raising the sound volume above 100%
directly from the system menu if the feature is enabled via the
`allow-volume-above-100-percent` key in `org.gnome.desktop.sound`.
Add a debug command (to be executed manually via Alt+F2) to check
that all of gnome-shell's file descriptors have the CLOEXEC flag set.
This is important so that internal file descriptors do not get passed
to apps when they are launched.
It prints a warning message for every fd that does not have the flag set.
fdwalk() is used from the standard library if available (it is not
available in glibc), otherwise we use the same implementation as glib
has internally.

When the amount of free memory on the system is somewhat low, gnome-shell
will sometimes fail to launch apps, reporting the error:
fork(): Cannot allocate memory
fork() is failing here because while cloning the process virtual address
space, Linux worries that the thread being forked may end up COWing the
entire address space of the parent process (gnome-shell, which is
memory-hungry), and there is not enough free memory to permit that to
happen. This check is somewhat irrelevant because we are only forking
to immediately exec(), which will discard the whole virtual address
space anyway.
This issue can be avoided by using a new optimized gspawn codepath in
the latest glib development version, which uses posix_spawn() internally.
For the optimized codepath to be used, we must not pass a child_setup
function, so the the file descriptor management is reimplemented here
using new glib API to pass fds to the child process. The old API will
continue to be used on older glib versions.
We must also change the spawn flags for this code path to be hit.
I checked that gnome-shell's open file descriptors are all CLOEXEC
so using G_SPAWN_LEAVE_DESCRIPTORS_OPEN should be safe.
This will result in more resilient app launching when memory is low,
since the optimized spawn path avoids cloning the virtual address
space of the parent process (gnome-shell) and avoids the irrelevant
memory overcommit check.

Some systems define it to /usr/lib64 on 64-bit systems, which is not
where systemd looks for unit files. Just hardcode 'lib' in the install
prefix until we get to use the pkg-config file.

So that we can be started by systemd --user, instead of gnome-session.
There are three units:
- gnome-shell.service: Start gnome-shell itself.
- gnome-shell-x11.target, gnome-shell-wayland.target: Sync points for
units that need to care if x11 or wayland is in use.
gnome-settings-daemon will use these, for example.

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

Package managers usually take care of compiling GSettings schemas and
updating the .desktop database on installation, but when building
manually from source, we should perform the aforementioned actions
ourselves.

find_program() defaults to require the program in question, and as
failing to locate it is now fatal, there's no longer a need for
checking whether it was found later.
