Add a selftest for migration support in guest library and test harness
code. It performs migrations a tight loop to irritate races, and has
flushed out several bugs in developing in the complicated test harness
migration code already.

x86/sieve.c is used by s390x and arm via symbolic link. Make a new
directory common/ for architecture-independent tests and move

Console output required to support migration becomes quite noisy
when doing lots of migrations. Provide a migrate_quiet() call that
suppresses console output and doesn't log.

Using 1 and 2 for source and destination is confusing, particularly
now with multiple migrations that flip between them. Do a rename
pass to tidy things up.

Support multiple migrations by flipping dest file/socket variables to
source after the migration is complete, ready to start again. A new
destination is created if the test outputs the migrate line again.
Test cases may now switch to calling migrate() one or more times.

Starting a pipeline of jobs in the background does not seem to have
a simple way to reliably find the pid of a particular process in the
pipeline (because not all processes are started when the shell
continues to execute).
The way PID of QEMU is derived can result in a failure waiting on a
PID tha
Rather than put a big script into the trap handler, have it call
a function.

Migration files weren't being removed when tests were interrupted.

Thomas suggested I should split this out of the powerpc series
because it is applicable to other archs as well and it's easier
for others to review like this.
Since the v5 series:
- Split out from powerpc changes
- Fixed another small race found when running migration tests
