Richard Purdie d0b7471ba8 bitbake: runqueue: Fix task migration problems
Tasks were not migrating consistently, particularly:

* if a task was rehashed which had already run
* if a task which was valid became invalid due to a rehash

We need to always run the migration code for rehashed tasks and then
reprocess them for hash validity. This means rearranging the code.

It also means several tests are no longer correct and can't be written
correctly to work on all possible workflows so those are removed.

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.
