Convert test to use only ext4 instead of 300M demanding XFS.
Shorten 'B' files to 4K and use 4K strip size with >raid1 arrays
so we do not risk spreading of the file across stripe.
Also use easier 'aux corrupt_dev()' method to introduce a bit
corruption into a block device with integrity.
TODO: shorten _wait_recalc (should't be needed).
Add function to corrupt some bytes in give file path presenting
a device. 1st. patern in just once replaced with 2nd. pattern.
Usable to simulate some bit corruption for integrity devices.
Convert test to use a single skeleton and only different pieces
keep in separate tests.
Lower raid disk usage to smaller size and switch to ext4
as way less demanding fileystem.
Instead of using size of 'empty header' in vdopool use fixed size 4K
for a 'wrappeing' vdo-pool device.
This fixes the issue when user tried to activate vdo-pool after
a conversion from vdo managed device with 'vgchange -ay' - where
this command activated all LVs with 'vdo-pool' wrapping device as well,
but this converted pool uses 0-length header.
This 4k size should usually prevent other tools like 'blkid' recognize
such device as anything - so it shouldn't cause any problems with
duplicate indentification of devices.
Correcting output results from configure script when
printing locking dir.
Shuffle dmfilemapd close to dmeventd option and tracing.
Couple indent changes.
syscall 186 is specific to x86 64bit. As this is different from arch
to arch and between same arch different arch size we will only grab
thread ID using built-in python support if it is supported.

When the daemon is starting we do an initial fetch of lvm state. If we
happened to get some type of failure with lvm during this time we would
exit. During error injection testing this happened enough that
the unit tests were unable to finish. Add retries to ensure we can get
started during error injection testing.
Previously we were injecting a missing key in the lv, vg, and pv.
Given the order of processing in lvmdbusd, this prevented us from
exercising all the error paths. Change to returning just 1 instead.
When we sort the LVs, we can stumble on a missing key, protect against
this as well.
Seen in error injection testing:

Remove old code that became incorrect at some point.
It's probably a fragment of an old condition that was left
behind because it wasn't understood. We don't want to drop
the MISSING_PV flag just because the PV has no mda in use.
The device that was missing may have stale data, so the user
needs to decide if the device should be removed or restored.
Different sequences of steps that could be used to handle raid LVs
after VG takeover (what would happen in cluster failover) combined
with the loss of a disk.
