This reverts commit 45bd7b39a4.
The database for users on NixOS 20.09 is still encrypted so we don't
need this wrapper for users that upgrade from NixOS 20.09 to 21.05.
Starting Cagebreak as X11 client doesn't work anymore as wlroots 0.13
started to require the DRI3 extension which isn't supported by LLVMpipe:

The test broke after updating Cagebreak in #121652 (bf8679ba94).
XWayland still fails for unknown reasons:
Modifiers specified, but DRI is too old
libEGL warning: DRI2: failed to create dri screen
libEGL warning: NEEDS EXTENSION: falling back to kms_swrast
glamor: No eglstream capable devices found
glamor: 'wl_drm' not supported
Missing Wayland requirements for glamor GBM backend
Missing Wayland requirements for glamor EGLStream backend
Failed to initialize glamor, falling back to sw

The fallback to software rendering is to be expected but it looks like
XWayland is crashing with "failed to write to XWayland fd: Broken pipe".
Most programs already run natively under Wayland so extraSessionCommands
isn't as important anymore. XWayland is already covered by
"programs.xwayland.enable = mkDefault true;" in the module.
AFAIK this is the only reliable way for us to ensure SQLCipher will be
loaded instead of SQLite. It feels like a hack/workaround but according
to the SQLCipher developers [0] "this issue can and should be handled
downstream at the application level: 1. While it may feel like a
workaround, using LD_PRELOAD is a legitimate approach here because it
will substitute the system SQLite with SQLCipher which is the intended
usage model;".
This fixes#108772 for NixOS 20.09 users who upgrade to NixOS 21.05 and
replaces #117555.
For nixos-unstable users this will unfortunately break everything again
so we should add a script to ease the transition (in a separate commit
so that we can revert it for NixOS 21.05).

Well, this should test if the database is encrypted but currently it is
still unencrypted and we need to notice if this behaviour changes in the
future (as it will cause data loss, see e.g. #108772).
Anyway, this doesn't really matter for security reasons but we need this
test to prevent data loss (unfortunately Signal-Desktop and SQLCipher
handle this badly... :o).
This test is important to confirm that $WAYLAND_DISPLAY is correctly
imported via "dbus-update-activation-environment --systemd" which is
done by default since #122605 (00e8e5b123).
It ensures that the gnome3-pinentry pop-ups work as expected to avoid
regressions like #119445 (which also broke screen sharing).
This seems like a good idea in general and will at least make it easier
to get screen sharing to work (but still requires a proper NixOS
configuration including xdg-desktop-portal-wlr).
Note: It isn't necessary to set XDG_SESSION_TYPE=wayland as wlroots
already takes care of it (currently at least for the logind and libseat
session backends, the next wlroots release will require libseat):
https://github.com/swaywm/wlroots/blob/4839664a9209e2829f3f90006065229b5c17007c/backend/session/session.c#L80
The default config.in template contains
"include @sysconfdir@/sway/config.d/*" but we've dropped it to better
support non-NixOS (which seems like a mistake in retrospect).
This restores that behaviour and extends the default configuration via
nixos.conf to fix#119445.
Note: The security configurations (security.d) where dropped entirely
(but maybe they'll return).
Only "wayland_scanner" and "Version" are required so it's easier to
create wayland-scanner.pc manually than to copy it from $dev and avoid
dependency cycles.
This adds a basic test for Sway. Because Sway is an important part of
the Wayland ecosystem, is stable, and has few dependencies this test
should also be suitable for testing core packages it depends on (e.g.
wayland, wayland-protocols, wlroots, xwayland, mesa, libglvnd, libdrm,
and soon libseat).
The test is modeled after the suggested way of using Sway, i.e. logging
in via a virtual console (tty1) and copying the configuration from
/etc/sway/config (we replace Mod4 (the GNU/Tux key - you've replaced
that evil logo, right? :D) with Mod1 (Alt key) because QEMU monitor's
sendkey command doesn't support the former).
The shell aliases are used to make the sendkey log output shorter.

On my system I have XWayland disabled and therefore only WAYLAND_DISPLAY
is set. This ensures that the graphical output will still be enabled on
such setups (both Wayland and X11 are supported by the viewer).
We had to use fetchgit so far as the tarballs are generated on demand
and have embedded timestamps which makes their hashes unstable [0][1].
This is a problem for fetchurl but fetchzip extracts the tarballs into
the Nix store and therefore the contents will get normalized and the
hashes remain stable.

See [0]: "QEMU_OPTS is something that should be set by people running VM
tests interactively, to do port forwardings etc.
We really should not poke with it from the test script - that's what
virtualisation.qemu.options is for."

See #119615 for more details. The aarch64-linux test failed with
"qemu-system-aarch64: Virtio VGA not available" so I've restricted the
test to x86_64-linux (the virtio paravirtualized 3D graphics driver is
likely only available on very few platforms).
The result still looks far from ideal but at least it gets recognized
now. "-fa Monospace" is required to switch to a font from the FreeType
library so that "-fs 24" works.
Note: Using linuxPackages_latest is not required anymore.
