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
