Richard Purdie 2ffbb020fe bitbake: bitbake-worker: Try and avoid potential short write events issues
We're seeing occasional issues where builds fail as events were written from the
worker children in the form <event>partial data<event>full event</event>.

This causes failures as bitbake server can't parse that and exits. This could
be due to short writes to the worker event pipe which we weren't checking. Check
this and loop accordingly. Also add some asserts to detect other potential causes.

Thanks to Joshua Watt for help in spotting the issue.

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.
