80b717af0c commands: cheap optimisation for parser

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
path is used.

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.

6a5c9ba349 commands: use existing vg/lv name parsing functions 
inside the new lv arg parsing function.

This includes getting the VG name from the env var,
and some added checks on the format of the vg/lv string.

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 
There was a small flaw in the logic regarding when LVM_VG_NAME
can replace a VG position 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.

46b2599d5c lvconvert: use command defs for raid/mirror types 
All lvconvert functionality has been moved out of the
previous monolithic lvconvert code, except conversions
related to raid/mirror/striped/linear.  This switches
that remaining code to be based on command defs, and
standard process_each_lv arg processing.  This final
switch results in quite a bit of dead code that is
also removed.
