fe0922b8a6 dmsetup: simplify branching in _stats_update_file()
The fallback branch in _stats_update_file() is redundant (since the
branch taken when the daemon starts successfully must jump to the
'out' label anyway): remove it and re-order the conditions to
improve readability.

396377bc03 pre-release
Removing some unused new lines and changing some incorrect "can't
release until this is fixed" comments.  Rename license.txt to make
it clear its merely an included file, not itself a licence.

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

6165e09221 lvchange: reject setting all raid1 images to writemostly
raid1 doesn't allow to set all images to writemostly because at
least one image is required to receive any written data immediately.

The dm-raid target will detect such invalid request and
fail it iwith a kernel error message.

Reject such request in uspace displaying a respective error message.

0dabe7237c commands: fix commands with run with path basename
The recent command definitions commit took the command
name from argv[0] without applying basename to the value,
so a pathname, e.g. /usr/sbin, would cause lvm to not
recognize the command name.

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)

3be2e61c9f Revert "lvcreate: continue to accept --thinpool with -L and -V but not -T"
This reverts commit 642d682d8d.

Using the thinpool option with this cmd def makes it
indistinct from other cmd defs where thinpool is a
required option.

642d682d8d lvcreate: continue to accept --thinpool with -L and -V but not -T
lvcreate --thinpool POOL1 -L 100M --virtualsize 100M snapper_thinp

https://bugzilla.redhat.com/1434027

(The general rule is that a command is accepted if it is unambiguous.
The combination -L -V --thinpool uniquely identifies the operation.)

38292ca1d0 commands: fix command matching for unused options
When a given command:

- matches command definition A based on required options,
  but uses optional options that are not accepted by A.

- matches command definition B based on required options,
  (but fewer required items than A), and uses no
  unaccepted optional options.

then B is the correct choice.  Command A would fail because
of the unaccepted optional options.  The logic was mistakenly
letting A win because it had a greater number of required option
matches, without accounting for the optional option mismatches.

49cd54fc3a commands: fix lvcreate mirrors/stripes options
Systematically outline every combination of:
--type striped, --type mirror, --type raid, --mirrors, --stripes
and make sure each is assigned to one specific cmd def.

This revealed that a new command def is needed for
lvcreate that uses both --mirrors and --stripes
but no --type option.

The use of LVCREATE_RAID shortcut for an option set
resulted in mirrors/stripes being included in optional
opts set when they were already in the required list.

c8671f6f79 commands: use correct relative signs with mirror option
As was recently done with relative signes for sizes/extents,

lvcreate --mirrors now does not accept or advertise an
optional minus sign with the value.  lvconvert --mirrors
accepts +|-.

15682270f4 commands: fix lvconvert options for mirrors/stripes
The LVCONVERT_RAID shortcut for including options ended
up including mirrors/stripes as optional opts in defs where
they were already required, or in defs where they would
not be used.  Remove the option set and specify in each
case only the options wanted.

4d0793f0ec pool: rework handling of passed args
As now we can properly recognize all paramerters for pool creation,
we may drop PASS_ARG_  defines and rely on '_UNSELECTED' or 0 entries
as being those without user given args.

When setting are not given on command line - 'update' function
fill them from profiles or configuration. For this  'profile' arg
was needed to be passed around and since  'VG' itself is not needed,
it's been all replaced with 'cmd, profile, extents_size' args.

Reuse same code for getting/setting cache parameters with lvcreate.

So there is single one place how to get vars from profiles and configs.

Variables declarations are moved to start of function and
there is no need to initialize them as they are always
defined by functions get_cache_params() and get_pool_params().
