Provide an additional way to request the block layer to prioritize
foreground I/O over background I/O. This patch prepares for tests with
the mq-deadline I/O scheduler. While CFQ and BFQ support a "weight"
cgroup attribute, the mq-deadline scheduler does not. The mq-deadline
I/O scheduler only supports the I/O priority class for differentiating
I/O priorities.
The io.prio.class attribute is declared optional since this attribute
only exists if CONFIG_BLK_CGROUP_IOPRIO != n in the kernel
configuration.

Despite 'require_root: true' in Android.bp for CtsInitTestCases, it can
happen that this test is run without root privileges. If that happens,
skip the ServiceStopTest.

There's a bug previsouly where we compare return value of
GetCowOpSourceInfoData() with CowOperationType. Such bugs are possible
because cow operation enums are weakly typed integers. Turn
CowOperationType into strongly typed enum to prevent such bugs.

The root cause of "After OTA, device is not responding" is that
Service::Stop() did not stop services that had been migrated to another
v2 cgroup. Add a unit test for that scenario.

CL 2828279 doesn't do what it's description says that it does. Making
Service::Stop() work for processes that have been migrated to another v2
cgroup requires changing DoKillProcessGroupOnce(). Hence this CL that
removes the early return statements from DoKillProcessGroupOnce().

Right now there is a bug in second-stage-init that screws up the
overlayfs overrides. This happens because:
1. second-stage-init mount_all might be executed in the "bootstrap"
mount namespace.
2. In order to move (MS_MOVE) submounts in fs_mgr_overlayfs_mount_all(),
we change the mount propagation type of overridden filesystems to
MS_PRIVATE.
3. This means that the "default" mount namespace would not receive the
mount events of the overlayfs overrides.
4. After /data is mounted, init would switch to the "default" namespace.
This means any new processes spawned after this period would not be
able to see the overlayfs overrides.
We fix this by changing the mount order of second-stage-init mount_all
to mount the overlayfs override of a partition immediately after the
partition is mounted. This way we don't need to move any submounts as
there can't be any, thus we don't need to set any mountpoint to
MS_PRIVATE so the mount event of the overlayfs would be propagated to
the "default" mount namespace, too.
