David Teigland e59027e4f7 devices file: back up each version
Create backup copies of system.devices in /etc/lvm/devices/backup
named system.devices-YYYYMMDD.HHMMSS.NNNN.  NNNN is the version
counter from the file.

Each time that an lvm command writes a new system.devices file,
it also writes the same file in the backup directory.

A new comment line is added to system.devices with HASH=<num>
where <num> is a crc calculated from the uncommented lines in
system.devices.  This lets lvm detect if the file has been
modified outside of lvm itself.

If system.devices is edited directly, the next time a command
reads the file, the crc will not match the HASH value.  The
command will then rewrite system.devices with the correct HASH
value, and create a backup reflecting the edits.

A default limit of 50 backup files is kept, configurable by
lvm.conf devicesfile_backup_limit (set to 0 to disable backups.)
