Prevent lvresize from being able to resize internal LVs: mirror legs
(*_mimage_*), mirror log (*_mlog), snapshot placeholder LVs (snapshot*)
and others. Resizing these would leads to unexpected metadata and
sometimes crashes (in case of growing snapshot*).
Allow the number of logical extents to be expressed (for a snapshot) as
a percentage of the total space in the Origin Logical Volume with the
suffix %ORIGIN.
Update the relevant man pages accordingly. Eliminate inconsistencies
between the man pages and tools/commands.h

- fix missing unlocking of VG
lvcreate -l 100%PVS -n lv1 vg_test
Please specify physical volume(s) with %PVS
Internal error: Volume Group vg_test was not unlocked
- if no PVS specified, use all available
Fix segfault if %PVS in lvresize without PVs list.
Fix vg_read() error paths to properly release upon vg_read_error().
Note that in the iterator paths (process_each_*()), we release
inside the iterator so no individual cleanup is needed. However there
are a number of other places we missed the cleanup. Proper cleanup
when vg_read_error() is true should be calling vg_release(vg), since
there should be no locks held if we get an error (except in certain
special cases, which IMO we should work to remove from the code).
Unfortunately the testsuite is unable to detect these types of memory
leaks. Most of them can be easily seen if you try an operation
(e.g. lvcreate) with a volume group that does not exist. Error
message looks like this:
Volume group "vg2" not found
You have a memory leak (not released memory pool):
[0x1975eb8]

The backup() call store metadata from memory.
But in cluster backup() call performs
remote nodes metadata backup and it reads data from disk.
For metadata backup consistency,
patch moves all backup() calls after vg_commit.
(Moreover, some tools already do that this way.)
Using argv[] list in exec_cmd() to allow more params for external commands.
Fsadm does not allow checking mounted filesystem.
Fsadm no longer accepts 'any other key' as 'no' answer to y/n.
Fsadm improved handling of command line options.
BEFORE:
tools/lvm lvresize -l +4 vg22/lv1linear
Volume group "vg22" not found
Volume group vg22 doesn't exist
AFTER:
tools/lvm lvresize -l +4 vg22/lv1linear
Volume group "vg22" not found
Fix unfilled paramater passed to fsadm from lvresize
Update fsadm to call lvresize if the partition size differs (with option -l)
Fix fsadm to support vg/lv name (like the rest of lv-tools)
Fix missing VG unlocks in some pvchange error paths.
Add some missing validation of VG names.
Rename validate_vg_name() to validate_new_vg_name().
Change orphan lock to VG_ORPHANS.
Change format1 to use ORPHAN as orphan VG name.
e.g. lvcreate -l 100%FREE to create an LV using all available space.
lvextend -l 50%LV to increase an LV by 50% of its existing size.
lvcreate -l 20%VG to create an LV using 20% of the total VG size.
Add --config for overriding most config file settings from cmdline.
Quote arguments when printing command line.
Remove linefeed from 'initialising logging' message.
Add 'Completed' debug message.
Don't attempt library exit after reloading config files.
Always compile with libdevmapper, even if device-mapper is disabled.
