5507307b5f lvconvert: use command defs for raid/mirror types
All lvconvert functionality has been moved out of the
previous monolithic lvconvert code, except conversions
related to raid/mirror/striped/linear.  This switches
that remaining code to be based on command defs, and
standard process_each_lv arg processing.  This final
switch results in quite a bit of dead code that is
also removed.

81e84556b5 process_each_lv: add check_single_lv function
The new check_single_lv() function is called prior to the
existing process_single_lv().  If the check function returns 0,
the LV will not be processed.

The check_single_lv function is meant to be a standard method
to validate the combination of specific command + specific LV,
and decide if the combination is allowed.  The check_single
function can be used by anything that calls process_each_lv.

As commands are migrated to take advantage of command
definitions, each command definition gets its own entry
point which calls process_each for itself, passing a
pair of check_single/process_single functions which can
be specific to the narrowly defined command def.

c903d0e4b3 commands: new method for defining commands
. Define a prototype for every lvm command.
. Match every user command with one definition.
. Generate help text and man pages from them.

The new file command-lines.in defines a prototype for every
unique lvm command.  A unique lvm command is a unique
combination of: command name + required option args +
required positional args.  Each of these prototypes also
includes the optional option args and optional positional
args that the command will accept, a description, and a
unique string ID for the definition.  Any valid command
will match one of the prototypes.

Here's an example of the lvresize command definitions from
command-lines.in, there are three unique lvresize commands:

lvresize --size SizeMB LV
OO: --alloc Alloc, --autobackup Bool, --force,
--nofsck, --nosync, --noudevsync, --reportformat String, --resizefs,
--stripes Number, --stripesize SizeKB, --poolmetadatasize SizeMB
OP: PV ...
ID: lvresize_by_size
DESC: Resize an LV by a specified size.

lvresize LV PV ...
OO: --alloc Alloc, --autobackup Bool, --force,
--nofsck, --nosync, --noudevsync,
--reportformat String, --resizefs, --stripes Number, --stripesize SizeKB
ID: lvresize_by_pv
DESC: Resize an LV by specified PV extents.
FLAGS: SECONDARY_SYNTAX

lvresize --poolmetadatasize SizeMB LV_thinpool
OO: --alloc Alloc, --autobackup Bool, --force,
--nofsck, --nosync, --noudevsync,
--reportformat String, --stripes Number, --stripesize SizeKB
OP: PV ...
ID: lvresize_pool_metadata_by_size
DESC: Resize a pool metadata SubLV by a specified size.

The three commands have separate definitions because they have
different required parameters.  Required parameters are specified
on the first line of the definition.  Optional options are
listed after OO, and optional positional args are listed after OP.

This data is used to generate corresponding command definition
structures for lvm in command-lines.h.  usage/help output is also
auto generated, so it is always in sync with the definitions.

Every user-entered command is compared against the set of
command structures, and matched with one.  An error is
reported if an entered command does not have the required
parameters for any definition.  The closest match is printed
as a suggestion, and running lvresize --help will display
the usage for each possible lvresize command.

The prototype syntax used for help/man output includes
required --option and positional args on the first line,
and optional --option and positional args enclosed in [ ]
on subsequent lines.

  command_name <required_opt_args> <required_pos_args>
          [ <optional_opt_args> ]
          [ <optional_pos_args> ]

Command definitions that are not to be advertised/suggested
have the flag SECONDARY_SYNTAX.  These commands will not be
printed in the normal help output.

Man page prototypes are also generated from the same original
command definitions, and are always in sync with the code
and help text.

Very early in command execution, a matching command definition
is found.  lvm then knows the operation being done, and that
the provided args conform to the definition.  This will allow
lots of ad hoc checking/validation to be removed throughout
the code.

Each command definition can also be routed to a specific
function to implement it.  The function is associated with
an enum value for the command definition (generated from
the ID string.)  These per-command-definition implementation
functions have not yet been created, so all commands
currently fall back to the existing per-command-name
implementation functions.

Using per-command-definition functions will allow lots of
code to be removed which tries to figure out what the
command is meant to do.  This is currently based on ad hoc
and complicated option analysis.  When using the new
functions, what the command is doing is already known
from the associated command definition.

a warning to syslog when it exceeds 80% full.
The warning is repeated when more then 85%, 90% and 95%
of the thin pool is filled. See
.BR lvm.conf (5).
When a thin pool fills over 50% (data or metadata) thin plugin calls
configured \fIdmeventd/thin_command\fP with every 5% increase.
With default setting it calls internal
\fBlvm lvextend --use-policies\fP to resize thin pool
when it's been filled above configured threshold
\fIactivation/thin_pool_autoextend_threshold\fP.
If the command fails, dmeventd thin plugin will keep
retrying execution with increasing time delay between
retries upto 42 minutes.
User may also configure external command to support more advanced
maintenance operations of a thin pool.
Such external command can e.g. remove some unneeded snapshots,
use \fBfstrim\fP(8) to free recover space in a thin pool,
but also can use \fBlvextend --use-policies\fP if other actions
have not released enough space.
Command is executed with environmental variable
\fBLVM_RUN_BY_DMEVENTD=1\fP so any lvm2 command executed
in this environment will not try to interact with dmeventd.
To see the fullness of a thin pool command may check these
two environmental variables
\fBDMEVENTD_THIN_POOL_DATA\fP and \fBDMEVENTD_THIN_POOL_DATA\fP.
Command can also read status with tools like \fBlvs\fP(8).

lvconvert changes the LV type and includes utilities for LV data
maintenance. The LV type controls data layout and redundancy.
The LV type is also called the segment type or segtype.
To display the current LV type, run the command:
.B lvs \-o name,segtype
.I LV
The
.B linear
type is equivalent to the
.B striped
type when one stripe exists.
In that case, the types can sometimes be used interchangably.
In most cases, the
.B mirror
type is deprecated and the
.B raid1
type should be used. They are both implementations of mirroring.
In some cases, an LV is a single device mapper (dm) layer above physical
devices. In other cases, hidden LVs (dm devices) are layered between the
visible LV and physical devices. LVs in the middle layers are called sub LVs.
A command run on a visible LV sometimes operates on a sub LV rather than
the specified LV. In other cases, a sub LV must be specified directly on
the command line.
Sub LVs can be displayed with the command

lvcreate creates a new LV in a VG. For standard LVs, this requires
allocating logical extents from the VG's free physical extents. If there
is not enough free space, then the VG can be extended (see
\fBvgextend\fP(8)) with other PVs, or existing LVs can be reduced or
removed (see \fBlvremove\fP, \fBlvreduce\fP.)
To control which PVs a new LV will use, specify one or more PVs as
position args at the end of the command line. lvcreate will allocate
physical extents only from the specified PVs.
lvcreate can also create snapshots of existing LVs, e.g. for backup
purposes. The data in a new snapshot LV represents the content of the
original LV from the time the snapshot was created.
RAID LVs can be created by specifying an LV type when creating the LV (see
\fBlvmraid\fP(7)). Different RAID levels require different numbers of
unique PVs be available in the VG for allocation.
Thin pools (for thin provisioning) and cache pools (for caching) are
represented by special LVs with types thin-pool and cache-pool (see
\fBlvmthin\fP(7) and \fBlvmcache\fP(7)). The pool LVs are not usable as
standard block devices, but the LV names act references to the pools.
Thin LVs are thinly provisioned from a thin pool, and are created with a
virtual size rather than a physical size. A cache LV is the combination of
a standard LV with a cache pool, used to cache active portions of the LV
to improve performance.
.SS Usage notes
In the usage section below, \fB--size\fP \fINumber\fP can be replaced
in each case with \fB--extents\fP \fINumberExtents\fP. Also see both
descriptions the options section.
In the usage section below, \fB--name\fP is omitted from the required
options, even though it is typically used. When the name is not
specified, a new LV name is generated with the "lvol" prefix and a unique
numeric suffix. Also see the description in the options section.

pvmove moves the allocated physical extents (PEs) on a source PV to one or
more destination PVs. You can optionally specify a source LV in which
case only extents used by that LV will be moved to free (or specified)
extents on the destination PV. If no destination PV is specified, the
normal allocation rules for the VG are used.
If pvmove is interrupted for any reason (e.g. the machine crashes) then
run pvmove again without any PV arguments to restart any operations that
were in progress from the last checkpoint. Alternatively, use the abort
option at any time to abort the operation. The resulting location of LVs
after an abort depends on whether the atomic option was used.
More than one pvmove can run concurrently if they are moving data from
different source PVs, but additional pvmoves will ignore any LVs already
