Update tests Indent Shell improvements - use internal function for checks Use PVs in "" (LV and VG cannot have spaces) Several test very starting 'dmeventd' without annoucing it via prepade_dmeventd. Fix some of test actually.

Substantial rework of the functional test support code. Some new features: - somewhat neater, more consistent and more readable output - possible to set any lvm.conf value: aux lvmconf "section/key = value" - LVM_TEST_NODEBUG to suppress the (lengthy) "## DEBUG" output - back-substitution on test output ($TESTDIR/$PREFIX -> @TESTDIR@/@PREFIX@) - support code moved from test/ to test/lib/ --> less clutter

Disallow snapshots of mirror segment types. Snapshots of RAID logical volumes are allowed (including "raid1"). However, snapshots of "mirror" logical volumes has been disallowed due to unsolvable issues inherent to the design. The fact that mirroring (dm-raid1.c) must stop all I/O as the result of a failure and wait for userspace intervention can lead to a circular dependency if userspace is simultaneously waiting for snapshots (on mirrors) to make an I/O update before proceeding. Various snapshot on mirror tests have been removed as a result.

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.
