90423c1200 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.

ba428469e6 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.

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)

6f8bd07b40 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.

7a5a5cb06f Add some messages that indicate completion of RAID device replacement.
There were no messages printed upon completiion of RAID device replacement.
This could cause confusion/concern during automated recovery, because the
user sees the failure messages but no other messages indicating correction.

d81498a824 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.

96f82296ae 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.

1456c3b298 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.
