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 2011-01-05 03:16:18 +03:00			`. lib/test`

Fix test to use explicit /dev/mapper/ node, /proc/mounts should not change this... (failed on RHEL5) 2011-03-02 16:49:29 +03:00			`mount $DM_DEV_DIR/mapper/$vg-snap mnt`
