5406191cb9 lvchange: allow changing properties on thin pool data lv
Add an exception to not allowing lvchange to change properties
on hidden LVs.  When a thin pool data LV is a cache LV, we
need to allow changing cache properties on the tdata sublv of
the thin pool.

cf73f6cf61 lvcreate: Fix mirror percentage size calculations.
Trap cases where the percentage calculation currently leads to an empty
LV and the message:

  Internal error: Unable to create new logical volume with no extents

Additionally convert the calculated number of extents from physical to
logical when creating a mirror using a percentage that is based on
Physical Extents.  Otherwise a command like 'lvcreate -m3 -l80%FREE'
can never leave any free space.

This brings the behaviour closer to that of lvresize.
(A further patch is needed to cover all the raid types.)

54726a4950 fix running commands from a script file
Using any arg with a command name in a script file
would cause the command to fail.

The name of the script file being executed was being passed
to lvm_register_commands() and define_commands(), which
prevented command defs from being defined (simple commands
were still being defined only by name which was enough for those
to still work when run trivially with no args).

4f9ff14508 pvcreate: add prompt when setting dev size
If the device size does not match the size requested

Make the pvcreate checking/prompting code handle
multiple prompts for the same device, since the
new prompt can be in addition to the existing
prompt when the PV is in a VG.

a4f07b701a commands: check required option value when matching command
A command def can include a specific constant option value,
but the value was not being checked for optional opts.

e.g. this is an incorrect command and does not match any
command defs:

lvconvert --type cache --cachepool vg/lv

However, it was mistakely being matched to this cmd def,
where the required options match, but the optional options
do not:

lonvert --cachepool LV_linear_striped_raid_cachepool
OO: --type cache-pool, ...

The optional options were mistakely considered matching
because 'cache' and 'cache-pool' were not being compared.

7ccb4825c7 lvchange/lvconvert: fix missing lvmlockd LV locks
lvchange/lvconvert operations that do not require the LV
to already be active need to acquire a transient LV lock
before changing/converting the LV to ensure the LV is not
active on another host.  If the LV is already active,
a persistent LV lock already exists on the host and the
transient LV lock request is a no-op.

Some lvmlockd locks in lvchange were lost in the cmd def
changes.  The lvmlockd locks in lvconvert seem to have
been missed from the start.

a7d4156a9a lvchange: fix --poll value when set from option
The actual value specified by the --poll y|n option was not
being used.  The way the --poll value is used is hidden
through an indirection where the value is stored in a
global variable at the start of the command, and then the
value is read from there later.  Setting the global
variable early in the command had been lost with the
cmd def changes.

1c41898c07 vgchange/lvchange: fix poll and monitor use
Fill in some gaps where old versions of lvm allowed
--poll and --monitor in combination with other operations,
but those combinations had been lost since the cmd def work.
(The new cmd def code also added some combinations that
had been missed by the old code.)

Changes:

lvchange --activate: add poll and monitor options, and
                     add calls to them in implementation.

lvchange --refresh: add monitor option (poll already there),
                    and call to monitor in implementation.

lvchange <metadata ops>: add poll and monitor options, and
                         add calls to them in implementation.

vgchange <metadata ops>: add poll option (call to poll
                         already in implementation).

vgchange --refresh: remove monitor option (not used by code)

lvchange --persistent y: add poll and monitor options, and
                         add calls to them, and to activate
                         in the implementation. (Making it
                         match the main lvchange metadata
                         command.)

Summary of current usage:

lvchange --activate: monitor, poll
vgchange --activate: monitor, poll

lvchange --refresh: monitor, poll
vgchange --refresh: poll

lvchange --monitor: ok
lvchange --poll: ok
lvchange --monitor --poll: ok
vgchange --monitor: ok
vgchange --poll: ok
vgchange --monitor --poll: ok

lvchange <metadata ops>: monitor, poll
vgchange <metadata ops>: poll

162272e5a5 commands: ignore partial option in most cases
These days --partial is only used with activation in
lvchange/vgchange.  It probably had another meaning
at some point in history which is no longer used,
so ignore it in those cases.

When included in the OO list, the option is advertised in
help/man output, implying it is meaningful to the command,
when in fact the command never uses it.
The IO list means the option won't cause an error if it's
used, but is not displayed as an valid option for the command.
If the option is not included in either OO or IO lists,
using the option would cause a command error, which would cause
problems for anyone is using the option for historical reasons.
