c2c028c680 tests: reduce number of created LVs
lvm2 for a while already optimizes 'vgremove' operation to
a single commit when possible if all LVs can be
easily deactivated.

So the number of LVs doesn't matter much - but the tested
case 'test_delete_non_complete_job' seems to be taking
some time anyway to capture the exception.

So just reducing the running time of the test significatanly
as we don't need to create 64LVs for 4 'execution mode' runs.

60bad2f22d lv_types: sort order of types
Order is used for man page generation (although not completely).
So place  'zero & error' to the end of list.
Keep  linear,striped,snapshot in front.
For the rest use alphabetic order.

always production same results for all  'opt_enum' values

1a219c69ee lvmcmdline: runtime function resolving
Instead of resolving and storing 'command_fn'
withing 'struct command' use just funtion enum
and resolve function pointer just in place,
where it is really needed - first try to resolve
'new style' and fallback to 'old style' named.

bebbb1e66a command: use command_id_to_enum
Instead of storing command_id as string, direcly
translate string to enum index and use 'command_enum()'
to get string when needed for printing.

This way we can easily detect error in the structure
while parsing it - and we can later avoid separate
'translation' loop.

5840f90e82 command: refactor code for simplier lookup
We can more efficiently use command_name struct to
lookup for  lvm_command_enum and avoid many repeated
command name searches since we already know
the enum index that is now stored in 'struct command'.

82617852a4 lvmcmdline: use strcut as const
Constity members in cmdline_context, would be nice, to replace
this static struct with couple function calls.

Also replace some 'while' loops with for loops, so code
is more readable.

abe1b49b47 command: refactor struct command_name
Split struct command_name to the constant part (keep the name)
and new 'struct command_name_args' which holds runtime computed
info.   To get to the _args part - we can easily use
lvm_command_enum as equivalent index.

Constified part 'struct command_name' is now fully stored
in .data.rel.ro segment, while command_name_args part goes
to .bss segment.

Code will be further reduced with next refactoring.

1c396598ff command: futher move to single struct

b678decfca tests: kill process in flock group
There is no reason to wait for 10sec when removing 'vg' at test

for testing)

So the correction was OK, however we missed to fix also
cut&paste bug here - as the second check should be
actually checking  field->type.
