Richard Purdie a1f4d97bf8 bitbake: bitbake-worker: Allow shutdown/database flush of pseudo server at task exit
We have a problem where pseudo server processes exist after bitbake exits
and hold the pseudo database in memory. In a docker container, the processes
will be killed as the container is destroyed with no warning and no opportunity
to write the data to disk. This leads to permissions/inode corruptions and
data loss.

Send a shutdown message to pseudo which in new versions of pseudo will flush
the database, thereby fixing some of the issues people using docker containers
see.

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.
