[kvm-unit-tests,0/7] more migration enhancements and tests

Message

This series applies on top of the multi-migration patches and just
has assorted things I've been collecting.

- New migrate_skip() command that tidies up the wart of using
  migrate_once() to skip migration.
- New "continuous migration" mode where the harness just
  migrates the test contually while it is running.
- Put some migration tests in gitlab CI for powerpc and s390.
- Add a test case that can reproduce the QEMU TCG dirty bitmap
  migration bug.

Nicholas Piggin (7):
  arch-run: Keep infifo open
  migration: Add a migrate_skip command
  (arm|s390): Use migrate_skip in test cases
  powerpc: add asm/time.h header with delay and get_clock_us/ms
  arch-run: Add a "continuous" migration option for tests
  gitlab-ci: Run migration selftest on s390x and powerpc
  common: add memory dirtying vs migration test
