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

a12b3af033 lvchange: enhance avoiding multiple metadata updates/reloads/backups
Enhance commit 25b5915c9b
to process options requiring immediate metadata commits
and reloads after those we can group together doing just
one commit and an optional reload for the whole group.

Backup metadata after processing options successfully.

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.

25b5915c9b lvchange: avoid multiple metadata updates/reloads/backups
_lvchange_properties_single() processes multiple command
line arguments in a loop causing metadata updates and/or
backups per argument.

Optimize to only perform one update and/or backup
(but necessary interim ones; e.g. for --resync)
per command run.

36cac41115 man-generator/man/help: simplify hyphen escaping
Commits a29bb6a14b
    ... 5c199d99f4
narrowed down on addressing the escaping of hyphens
in the dynamic creation of manuals whilst avoiding
them in creating help texts.  This lead to a sequence
of slipping through hyphens adrressed by additional
patches in aforementioned commit series.

On the other hand, postprocessing dynamically man-generator
created and statically provided manuals catches all hyphens
in need of escaping.

Changes:
- revert the above commits whilst keeping man-generator
  streamlining and the detection of any '\' when generating
  help texts in order to avoid escapes to slip in

- Dynamically escape hyphens in manaual pages using sed(1)
  in the respective Makefile targets

- remove any manually added escaping on hyphens from any
  static manual sources or headers

14c4d32247 commands: fix combined thin pool and vol create defs
Fixes command defs related to creating a new thin pool and
then a new thin lv in the new pool.

1. lvcreate --size --virtualsize --thinpool
   Needs a cmd def, it was missing.
   The def is unique by the three required
   options: size, virtualsize and thinpool.

2. lvcreate --size --virtualsize --thinpool VG
   Needs a cmd def, it was missing.
   The def is unique by the three required
   options: size, virtualsize and thinpool,
   and one required positional arg: VG.

3. lvcreate --thin --virtualsize --size LV_new|VG
   This existing def should not accept an optional
   --type thin, which if used makes it indistinct
   from another def.

4. lvcreate --size --virtualsize VG
   This existing def should not accept an optional
   --type thin or --thin, which if used makes it
   indistinct from other defs (e.g. 3)
