Import a bunch of new tests by jstava. Mostly everything pass, they however tend to expose the lvremove -ff vg ordering bug.

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

Use PV UUID in hash for device name when exporting metadata. Currently code uses pv_dev_name() for hash when getting internal "pvX" name. This produce corrupted metadata if PVs are missing, pv->dev is NULL and all these missing devices returns one name (using "unknown device" for all missing devices as hash key).

vgcfgrestore: fix crash on restore of wrong vgname When vgname has not existed in metadata, it has crashed on double free in format_instance destroy() - since VG was created, used FID and was released - which also released FID, so further use was accessing bad memory. Fix it for this code path before release_vg() so FID will exists when _vg_read_file_name() returns NULL.

# vgcfgbackup correctly stores metadata LVM1 with missing PVs
Restrict lvm1 partial mode. Current lvm1 allocation code seems to not properly map segments on missing PVs. For now disable this functionality. (It never worked and previous commit just introduced segfault here.) So the partial mode in lvm1 can only process missing PVs with no LV segments only. Also do not use random PV UUID for missing part but use fixed string derived from VG UUID (to not confuse clvmd tests).
