RAID: Make "raid10" the default striped + mirror segment type

Browse Source 
When both the '-i' and '-m' arguments are specified on the command
line, use the "raid10" segment type.  This way, the native RAID10
personality is used through dm-raid rather than layering a mirror
on striped LVs.  If the old behavior is desired, the '--type'
argument to use would be "mirror" rather than "raid10".
