[kvm-unit-tests PATCH v1 0/4] s390x: add migration test suport

[Nico Boehr <nrb@linux.ibm.com>]

Add migration test support for s390x.

arm and powerpc already support basic migration tests.

If a test is in the migration group, it can print "migrate" on its console. This
will cause it to be migrated to a new QEMU instance. When migration is finished,
the test will be able to read a newline from its standard input.

We need the following pieces for this to work under s390x:

* read support for the sclp console. This can be very basic, it doesn't even
  have to read anything useful, we just need to know something happened on
  the console.
* s390/run adjustments to call the migration helper script.

  lib: s390x: add support for SCLP console read
  s390x: add support for migration tests
  s390x: don't run migration tests under PV
