7162a25b0b Support 16GB for thin pool metadata 
Add some hack math to allow 16GB devices to be passed as thinpool metadata.
Since kernel has put in limit to not allow which are just bigger then
some predefined constant in kernel but not matching 16GB so any device bigger
is rejected.

FIXME: Current code still might need more tweaks to be more generic.

6c7a6c07ee Add support for thin check 
Use libdm callback to execute thin_check before activation
thin pool and after deactivation as well.

the tool.

9c159ea320 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.

1babf24949 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)

d06f64dd29 Allow multiple device names with pvscan --lvmetad.

Adjust some log message severities.  (More changes needed.)

6a5706a3a5 Remove support for TRIM message

appearence of TRIM from libdm and lvm.

2ce9693341 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.

521ddeaecc 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.

24ab6328f7 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).

62e38da133 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.
