c33770c02d lvmlockd: do not allow mirror LV to be activated shared
This reverts 518a8e8cfb
  "lvmlockd: activate mirror LVs in shared mode with cmirrord"

because while activating a mirror LV with cmirrord worked,
changes to the active cmirror did not work.

b5f444d447 man: updates to lvmlockd
The terminology has migrated toward using "shared VG"
rather than "lockd VG".

Also improve the wording in a number of places.

e53cfc6a88 lvmlockd: update method for changing clustered VG
The previous method for forcibly changing a clustered VG
to a local VG involved using -cn and locking_type 0.
Since those options are deprecated, replace it with
the same command used for other forced lock type changes:
vgchange --locktype none --lockopt force.

f2ee0e7aca pvmove: require LV name in a shared VG
In a shared VG, only allow pvmove with a named LV,
so that only PE's used by the LV will be moved.
The LV is then activated exclusively, ensuring that
the PE's being moved are not used from another host.

Previously, pvmove was mistakenly allowed on a full PV.
This won't work when LVs using that PV are active on
other hosts.

f611b68f3c vgchange: separate change locktype and allow recovery
Add an independent command definition for "vgchange --locktype",
and split the implementation out of the set of common metadata
changes.  It is unlike normal metadata changes, and can only
be run by itself.  (Changing the lock type is similar in
principle to changing the VG name or the VG system ID; it
effects the ability of any host to see or access the VG.)

At some point this command lost the ability to forcibly change
the lock type of a shared VG to "none" (making it a local VG).
This can be necessary to repair shared VGs (e.g. recovery steps
that occur in vg_read are disabled for shared VGs because
they are not locked properly, or recovering sanlock locks
when the PV holding them is lost.)

"vgchange --locktype none --lockopt force VG" is used as the
method of forcing the shared VG to become local so that it
can be repaired.

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

ca905681cc man: Revise internal man page generation process.
For each section 8 man page, a .8_gen file is created from one of:
  .8_main            - Old-style man page - content used directly
  .8_des and .8_end  - Description and end section of a generated page
  .8_pregen	     - Pre-generated page used if the generator fails

Other man sections are not generated and use the suffix .5_main or .7_main.

Developers should use 'make generate' to regenerate the .8_pregen files.
