Jonathan Earl Brassow 3318c41356 Add ability to create mirrored logs for mirror LVs.
This check-in enables the 'mirrored' log type.  It can be specified
by using the '--mirrorlog' option as follows:
#> lvcreate -m1 --mirrorlog mirrored -L 5G -n lv vg

I've also included a couple updates to the testsuite.  These updates
include tests for the new log type, and some fixes to some of the
*lvconvert* tests.
