8a9c1b37ad Fix error path for create_toolcontext
Never return unfinished toolcontext - since error path is hit on
various stages of initialization we cannot leave it partially uninitialized,
since we would need to spread many more test across the code for config_valid.
Instead return NULL and properly release udev library resources as well.

dd121cf5ff Fix warn message and update man page
Fix regression in man page. The chunk size is in kilobyte units on command line
input though in the source code we work with sector size unit
so make it clear in the man page.

Update chunksize for thin pool in man page - it's max value is 1024M == 1G.

Fix warning range message to show proper max value.

3cf63e35bf Fit thin pool metadata into 128MB
If the lvcreate may decide some automagical values for a user,
try to keep the pool metadata size into 128MB range for optimal
perfomance (as suggested by Joe).

So if the pool metadata size and chunk_size were not specified,
try to select such values they would fit into 128MB size.

b608869a26 Check for multiple mangled names in auto mangling mode.
Auto mode can't deal with multiple mangled names. We can do that while working
in hex mode, but in auto mode, this would lead to device name ambiguity.

a const expression)

c3cb4bb872 Duplicate standard in/out descriptors for daemon
Addressing somewhat tricky bug here.
Since stdin,stdout,stderr were closed it's been occasionally possible to
see some unexpected messages to be flowing into a clvmd and generating some
randomly sized allocation of many megabytes. Since the message was not
being generated by standard send_message() construction, after some more
testing it apperead to be a debug log message - thus something has flown
to local socket opened on strandard out descriptor.

To fix the issue - use standard file descriptor duplication code for daemons.

For making easier debugging of polling daemon - developer might want to recompile
without modifition of standard file descriptors.

d6463f4890 Initialize dmeventd monitoring for every command
Read lvm.conf setting for monitoring for each command. So we should not
activate monitoring if the default compilation is set to monitor during
lvconvert commnads.

Patch also removes check for  clustered VG and allows to disable monitoring
for clustered VG with the assumption, the problem with monitoring and dmeventd
flag passing for INGNORE is already fixed.

d6f91a013b Change confusing message that is printed when a RAID device fails.
s/Issue/Use/, otherwise it is easy to misread "Issue" as "Issuing" - causing
the user confusion as to whether the action was performed automatically or
whether they need to issue the command.

7daa233e48 Fix possible NULL pointer dereferences when updating mirror log.
'_lv_update_log_type' takes a lvconvert_params argument so that it can pass
down the user's preference of 'region_size' and allocation_policy.  When
'mirror_remove_missing' was introduced (commit ID
95986e42a1) it didn't make sense to pass down
user preferences - so NULL was given instead.  While it may never happen in
practice, static analysis reveals that this argument could be dereferenced.
So, if the user preferences were not passed in, glean the necessary fields
from what is already set in the LV.
