46a75dedb4 Use new dmeventd_lvm2_command function in dmeventd plugins. 
For snapshot, prepare whole command in front into private buffer.
Add also some missing '\n' for syslog messages.
For raid and mirror only convert creation of command line string.
This should avoid any unbound growth of mempool for dm_split_names.

9e1ccf81c7 Drop extra stat before open of device 
Since the !(dev->flags & DEV_REGULAR) code path just called
dev_name_confirmed() which has just called 'stat()' inside,
remove duplicate second stat() call here.

88f8cbbb2e Do not lstat common path prefix 
When both path have identical prefix i.e. /dev/disk/by-id
skip  2 x lstat() for /dev  /dev/disk /dev/disk/by-id
and directly lstat() only different part of the path.

Reduces amount of lstat calls on system with lots of devices.

235028bf0f Add common initialization code for struct device

member values are initialized.

93bb35fd2b Always zalloc device structure 
Since there is zalloc behind the macro, put 'z' into the name.
Make the 'use_malloc' code path also using zalloc() call,
so it also give zeroed area.

49d06db518 Add policy based automated repair of RAID logical volumes 
The RAID plug-in for dmeventd now calls 'lvconvert --repair' to address failures
of devices in a RAID logical volume.  The action taken can be either to "warn"
or "allocate" a new device from any spares that may be available in the
volume group.  The action is designated by setting 'raid_fault_policy' in
lvm.conf - the default being "warn".
