The corosync cluster interface for clvmd did not correctly
deal with node up/down events so that when a node was removed
from the cluster clvmd would prevent remote operations
from happening, as it thought the node was up but not
running clvmd.
This patch fixes that code by simplifying the case to node
being up or down - which was the original intention
and is supported by pacemaker and CPG in the higher layers.

When NULL info struct is passed in - function is usable
as a quick query for lv_is_active_locally() - with a bonus
we may query for layered device.
So it could be seen as a more efficient lv_is_active_locally().
A know issue with kmem_cach is causing failures while testing
RAID 4/5/6 device replacement. Blacklist the offending kernel
so that these tests are not performed there.
Add internal devtypes reporting command to display built-in recognised
block device types. (The output does not include any additional
types added by a configuration file.)

Device Types Fields
-------------------
devtype_all - All fields in this section.
devtype_name - Name of Device Type exactly as it appears in /proc/devices.
devtype_max_partitions - Maximum number of partitions. (How many device minor numbers get reserved for each device.)
devtype_description - Description of Device Type.
> lvm devtypes
DevType MaxParts Description
aoe 16 ATA over Ethernet
ataraid 16 ATA Raid
bcache 1 bcache block device cache
blkext 1 Extended device partitions

The traditional style used for optional editable definitions
/* #define X /* */
produces a bogus warning from gcc -Wall.
Rather than suppressing this with -Wno-comment, switch over to
the // comment style.
Since our current vgcfgbackup/restore doesn't deal
with difference of active volumes between current and
restored set of volumes - run test with inactive LVs.
The lvm2-activation-net.service was ordered only with respect to iscsi
and fcoe service before. In addition to that, we also need ordering
with respect to lvm2-activation.service to prevent parallel vgchange -aay
runs which may cause some problems during activation.
See also https://bugs.gentoo.org/show_bug.cgi?id=480066.
With this patch, the ordering is firmly set to:
lvm2-activation-early.service -> lvm2-activation.service -> lvm2-activation-net.service

Rewrite check lv_on and add new lv_tree_on
Move more pvmove test unrelated code out to check & get sections
(so they do not obfuscate trace output unnecesserily)
Use new lv_tree_on()
NOTE: unsure how the snapshot origin should be accounted here.
Split pmove-all-segments into separate tests for raid and thins
(so the test output properly shows what has been skipped in test)
Update usage of "" around shell vars.
trim needs to trim both sides now.
trim also removes debug.log since it's only called when lvm command
has finished properly (so if something fails afterward, there
is no missleading debug trace in the log)
'die' evaluates given string - so \n could be used for
multiline error report
Also remove debug.log since the command finished properly when we
call 'die'
Note: we should not call 'die' after lvm command failure.
lvchange-raid.sh checks to ensure that the 'p'artial flag takes
precedence over the 'w'ritemostly flag by disabling and reenabling
a device in the array. Most of the time this works fine, but
sometimes the kernel can notice the device failure before it is
reenabled. In that case, the attr flag will not return to 'w', but
to 'r'efresh. This is because 'r'efresh also takes precedence over
the 'w'ritemostly flag. So, we also do a quick check for 'r' and
not just 'w'.
The DM_ACTIVATION and DM_UDEV_PRIMARY_SOURCE_FLAG needs to be kept the
way it was for backward compatibility (e.g. the old rules are still
in initramfs). This way the check in whether the device should be
scanned in 69-dm-lvmetad.rules is even easier.
Add a very simple hack for embeding /var/log/messages into
the tests output - it's not ideal since it sometimes breaks lines,
but still gives valuable info.
