f88ce5fb99 lvconvert: include swap behavior in generic pool syntax
For this syntax:
lvconvert --thinpool LV1 --poolmetadata LV2
lvconvert --cachepool LV1 --poolmetadata LV2

Restore the metadata swapping behavior in addition to
the pool creation behavior.  When LV1 is already a pool,
the metadata LV will be swapped with LV2.
When LV1 is not a pool, it will be converted to a
pool using the specified LV for metadata.

This syntax is no longer advertised because of the
ambiguous behavior.  The primary syntaxes for pool
creation and metadata swapping will be the advertised
methods.

56deed9d54 commands: compensate --uuid
As we now user binary search - it's nondeterministict
which of the same 'args' will be give - so duplicates
need 'extra' care.

So provide same hack for output for --uuidstr_ARG as
for input.

Solves 'pvscan -u'.

772834e40a commands: optimize binary search
Since there is a lot of options and lot of searches,
use binary search to keep strcmp at minimum.

The interesting part is - alphabetically sorted array contains
duplicates and some of them are not the 'right anwer', so
after we find matching string but not matching long_ARG,
we may need to check if the surrouding strings are the right matching
one.

The single loops is used also for strictly define --foo_long
(i.e. --stripes)  and just differs at final part.

TODO1: replace strstr call with some flag (just like short_opt).
TODO2: drop '--' from being stored and tests by strcmp.

298b11aed1 commands: track errors in command def parsing
When parsing command defs, track and report all
errors that are found.  Add an error return case
from define_commands so the standard error exit

1cb95fa5a0 commands: initialize commands[] once
When using liblvm2cmd, a process can do multiple
init/exit calls, i.e.

lvm2_init(); lvm2_run(); lvm2_exit();
lvm2_init(); lvm2_run(); lvm2_exit();
...

define_commands() needs to set up the global commands[]
definitions only the first time.

286d39ee3c lvconvert: handle old arg quirk when combining snapshot
The old ad hoc arg parsing when combining a split snapshot
allowed the first lv to have a vgname, but not the second.
Since lvconvert now uses the standard arg parsing in
process_each_lv(), the old one-off behavior requires a
work around.

d3af0e7528 lvcreate: LVM_VG_NAME applies even without name arg

7417c8acfa Revert "lvconvert: enable previous syntax to swap metadata"
This reverts commit 717363bb94.

These alternate forms for swapping metadata cannot be
distinguished from the command for creating a pool.
If we were to add these alternate forms for swapping
metadata, we would need to overload the pool creation
command defs, making those definitions ambiguous.
