598134b8e7 Pass struct device around internally rather than dev_t. 
Add 3rd daemon return state "unknown" for lookups that are carried out
successfully but don't find the item requested.
Avoid issuing error messages when it's expected that a device that's
being looked up in lvmetad might not be there.

197d0d4af6 Fix estimation of pool metadata device size 
If no size was give the later added minimal size check efectively
disable this code. Also the argument for size now must be kept
in sector_size, so adding division by SECTOR_SIZE (moved into
a const expression)

e3e0811b67 Allow multiple device names with pvscan --lvmetad. 
Hold global lock in pvscan --lvmetad.  (This might need refinement.)
Add PV name to "PV gone" messages.
Adjust some log message severities.  (More changes needed.)

7659a953a7 Remove support for TRIM message 
It's been unsupporte for now - and it's not going to be
implemented for thin pool kernel driver - so dropping
appearence of TRIM from libdm and lvm.

db424996be s/CPG_/CS_: Various CPG constants are going away, even though CPG itself stays 
F17 is getting rid of OpenAIS libraries (and checkpointing).  While the
CPG stuff is staying, some if its constants are being removed.  So, we
must adjust and use the remaining constants which the CPG constants were based on.

c53667ac45 Check for version string buffer 
Since lvm seems to call driver_version(NULL, 0)  this would lead
to crash. Though the combination of the code is probably very hard to hit.
If the user doesn't supply version buffer, just skip printing to buffer.

052269aa2c Wipe initial 4KiB for non-zeroed thin volumes 
If the thin pool has disabled zeroing  (created with -Zn), we at least
clear initial 4KiB of such thin volume (provisions 1st block).

If lvcreate is executed with '-an' command will abort (same way like we for
normal LV - however for normal LV option -Zn may skip clearing completely,
for thin volumes this option is not supported (applies only for pools).

50bdd70043 Allow cluster mirrors to handle the absence of the checkpoint lib (libSaCkpt). 
The OpenAIS checkpoint library is going away; therefore, cmirrord must
operate without it.  The algorithms the handle the timing of when to send
a checkpoint, the determination of what to send, and which ongoing cluster
requests are relevent with respect to the checkpoints are unaffected.  We
need only replace the functions that actually perform the storing/transmitting
and retrieving/receiving of the checkpoint data.  Rather than store the
checkpoint data in an OpenAIS checkpoint file, we simply transmit it along
with the message that notifies the incoming node that the checkpoint is
ready.

6508cc6805 Pass 'single_device' parameter down to suppress 'Can't find uuid' messages
