6859106e2a Add support for thin check 
Use libdm callback to execute thin_check before activation
thin pool and after deactivation as well.

Supporting thin_check_executable which may pass in extra options for
the tool.

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.

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.

526655301e Check allocated pointers 
Test pointers from allocation against NULL.
Error paths should be checked, some of them probably need
some extesions.

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 
when reading VG text metadate and called from pvscan --lvmetad.

(Longer-term, that check needs moving outside of that code.)

cd1f056f20 Use unsigned type for bitmask 
Using report_type_t for bitmask is not correct, since we have not defined types
for all  bit combinations - so switching to unsigned type, since values of
report_type_t enum are unsigned.

faf8ad30f1 Just code move of hash initialization in front of function 
Make sure both hash tables are initialized before _read_sections() call.
Presents no functional change (since PV scan phase was not adding LV hashes),
but makes the code easier to handle mem failing case, and static analyzer is
hapier as well.

4960a3c7f3 Add stack traces for lock_vol failures 
Adding at least stack traces with some FIXMEs for cases,
where we might want to do something cleaver - maybe fail command
or give user hints something is not going well ?

For remote_backup is stack probably 'good' enough for now.

3b45ebe86b Check id_write_format result

d7bb0d77aa Explicitely ignore fail error on hash_insert 
We cannot do anything better here anyway - we are already in logging function,
so just ignore this issue here - it will most likely stop application later.
