Ensure the mt::Signal lives at least as long as any callback runnning on the MainLoop.

This is (a) obviously more correct, and (b) *seems* to resolve a crazy deadlock where
the test blocks indefinitely waiting on a lock to be taken by

mirvanity: Avoid recording a spuriously low first sample due to thread
start-up races.

Although such a glitch would resolve itself and vanish at 50% test
completion, it's better to never see it at all because people will get

With this change the first sample recorded is much more likely to be
accurate and no longer an outlier that skews the results.

tests: split off the android and nested tests into their own suites (like mesa-kms and mesa-x11 have already done). make sure that the shared mtd::StubBuffer code is properly instantiating its NativeBuffer, given build conditions.

Fix bypass detection to not ignore partially intersecting buffers

Before the change the code would bypass the scene in the test case and just ignore the buffer that only partially overlaps with the full screen buffer buffer.

android: open FB HAL before HWComposer.

Some devices (for example Samsung Galaxy Tab 2 7.0) may insist that the
FB HAL be opened before HWC. This revision make HalComponentFactory to
comply to this requirement.

mtd::TriggeredMainLoop: fix spurious calls to fd sources.

FD_ISSET() is a side-effect-free expression, so this was just unconditionally calling *all* registered sources, regardless of which one(s) triggered the select().

Use the pixel format of the individual buffer stream to infer shaped()

It is a valid scenario to have an opaque buffer (or buffer stream) for the first layer in a surface and have further transparent or also opaque layers on top. This change removes the constant "non_rectangular" parameter of BasicSurface, and instead looks at the actual streams that are attached to surface.

With mir_presentation_queue it might be worth thinking about going one step further and actually look at the mg::Buffer that would be drawn next. An attempt to do so showed that it would require a few further refactoring steps in our integration test setup.
