This is the serious functionality change in this runqueue patch series of changes. Rather than two phases of execution, the scenequeue setscene phase, followed by normal task exeuction, this change allows them to execute in parallel together. To do this we need to handle marking of tasks as covered/uncovered in a piecemeal fashion on a task by task basis rather than in a single function. The code will block normal task exeuction until any setcene task which could cover that task is executed and its status is known. There is a slight optimisation which could be possible here at the risk of races but that doesn't seem worthwhile. The state engine isn't entirely cleaned up in this commit (see FIXME) and the setscenewhitelist functionality is broken by it (see following patches) however its good enough to test with normal workflows.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
