This hasn't worked for a while, since the test always runs the nested
backend, meaning it's a Wayland compositor. To unblock testing window
management in combination to monitor changes, lets remove the
unreachable X11 WM paths, so that we can start using virtual monitors.

util-private.h includes glib-i18n-lib.h, which requires GETTEXT_PACKAGE
to be defined. The define comes from config.h,
but that cannot be included in headers, so we have to make sure
that any source file that pulls in util-private.h (or a header
that includes it) includes config.h first.

In some hardware configurations, presentation timestamps could be
missing from some page flip events, leading to a temporary loss of
vblank synchronization.
This occurs at least with AMD GPUs for atomic commits that only update
the cursor plane. [0]
In those cases, it's better to calculate the next update time
according to the last valid presentation timestamp instead of relying
on the dispatch lateness.

The image build step is prone to race conditions, e.g. token changes. It
also tends to hit sporadic connection errors to FDO's gitlab. To
minimize the risk of these types of issues block pipelines, always retry
the image building step if it failed.
This has the unwanted consequence that changes to the image building
that results in the script actually failing, but right now there doesn't
appear to be a way to distinguish between actual build errors, and the
mentioned race conditions, as both cause the script to fail.

mutter needs GDK to use the x11 backend. It already calls
gdk_set_allowed_backends ("x11") for this purpose; however, if
GDK_BACKEND=wayland (or any other non-x11 backend possibly) happened to
be in the environment, GDK would fail to initialize at all. This would
result in mutter not registering as X11 window manager, and all X11
clients hanging.
Big thanks to Olivier Fourdan for figuring this out!
v2:
* Restore original value of GDK_BACKEND environment variable after
initializing GDK.

Both the fragend and vertend shader state was called
"CoglPipelineShaderState", which was rather annoying, especially when
the type needs to be exposed outside of the .c file as part of moving
out unit tests. Make the types unique. This also avoids confusing what
type one is looking at.

It consists of only a macro and build description logic.
Adds a macro for simpler tests that doesn't require a context; unit
tests requiring a context should use the same framework as conform
tests.

All working tests have already migrated to the test suite using mutter;
move the old unported tests over too, and remove the conform test
framework, as it is no longer used.
