386e91addb libdm: add dm_message_supports_precise_timestamps() 
Add a function to test whether the kernel precise_timestamps
feature is available in the current device-mapper driver version.

Presence of precise_timestamps also implies the availability of
latency histograms.

ce2e60ab45 lvmlockd: change log_error to log_debug for non error 
It's not uncommon for a command like vgchange -an to
deactivate and unlock LVs that were not active, so
don't lock that as an error.

7b570840cd lockd: no error when unlock fails 
The unlock call will fail in expected and normal cases,
and should not cause the command to fail.  (An actual
unlock in the lock manager should never fail.)

c1bd76d6fc configure: check for -lm and log10 function 
We already use -lm functions in a couple of places (these are
satisfied by gcc built-ins for most builds): add a configure.in
check and explicitly link to -lm.

12acf852c5 dmsetup: check timerfd reads for valid byte count (Coverity) 
The timerfd guarantees that it will return 8 bytes when a read(2)
is issued (a uint64_t giving the number of timer events during the
call). Check that it does so and log a non-fatal error if the byte
count is not 8.

4227b2ebb4 libdm-stats: only return uint64_t when required

only used to signal success/failure: change all these uses to
return a simple int instead.
