	tools          : args.h commands.h lvconvert.c lvcreate.c 

Log message:
	This patch changes the arguments that specify the mirror
	log type.  Previously, we had a '--corelog' argument that
	would change the default type from 'disk' to 'core'.  I
	think that creates too much confusion - especially when
	doing conversions on mirrors.
	
	The new argument '--log' takes either "disk" or "core"
	as a parameter.  This could be expanded in the future
	for additional logging types as well.
	
	Examples:
	# Creating a 2-way mirror
	$> lvcreate -m1 ... # implicitly use default disk logging
	$> lvcreate -m1 --log disk ... # explicit disk logging
	$> lvcreate -m1 --log core ... # specify core logging
	$> lvcreate -m1 --corelog ... # old way still works
	
	# Conversion examples
	$> lvconvert --log core ... # convert to core logging
	$> lvconvert --log disk ... # convert to disk logging
	$> lvconvert -mX --corelog ... # old way still works
	$> lvconvert -mX ... # old way of converting to disk logging still works
	
	Changes are reflected in the man pages.
