b5c8e591ed vdo: use defines also for configuration defines
Keep single source for most of values printed in lvm.conf
(still needs some conversion)

Correct max for logical threads to 60
(we may refuse some older configuration which might eventually
user higher numbers - but so far let's assume no user have ever set this
as it's been non-trivial and if would complicate code unnecessarily.)

Accept maximum of 4PiB for virtual size of VDO LV
(lvm2 will drop 'header borders to 0 for this case').

2c6a2b6e86 vdo: support vdo_pool_header_size
Add profilable configurable setting for vdo pool header size, that is
used as 'extra' empty space at the front and end of vdo-pool device
to avoid having a disk in the system the may have same data is real
vdo LV.

For some conversion cases however we may need to allow using '0' header size.

TODO: in this case we may eventually avoid adding 'linear' mapping layer
in future - but this requires further modification over lvm code base.

b4212be2e7 thin: improve 16g support for thin pool metadata
Initial support for thin-pool used slightly smaller max size 15.81GiB
for thin-pool metadata. However the real limit later settled at 15.88GiB
(difference is ~64MiB - 16448 4K blocks).

lvm2 could not simply increase the size as it has been using hard cropping
of the loaded metadata device to avoid warnings printing warning of kernel
when the size was bigger (i.e. due to bigger extent_size).

This patch adds the new lvm.conf configurable setting:
allocation/thin_pool_crop_metadata
which defaults to 0 -> no crop of metadata beyond 15.81GiB.
Only user with these sizes of metadata will be affected.

Without cropping lvm2 now limits metadata allocation size to 15.88GiB.
Any space beyond is currently not used by thin-pool target.
Even if i.e. bigger LV is used for metadata via lvconvert,
or allocated bigger because of to large extent size.

With cropping enabled (=1) lvm2 preserves the old limitation
15.81GiB and should allow to work in the evironement with
older lvm2 tools (i.e. older distribution).

Thin-pool metadata with size bigger then 15.81G is now using CROP_METADATA
flag within lvm2 metadata, so older lvm2 recognizes an
incompatible thin-pool and cannot activate such pool!

Users should use uncropped version as it is not suffering
from various issues between thin_repair results and allocated
metadata LV as thin_repair limit is 15.88GiB
Users should use cropping only when really needed!

Patch also better handles resize of thin-pool metadata and prevents resize
beoyond usable size 15.88GiB. Resize beyond 15.81GiB automatically
switches pool to no-crop version. Even with existing bigger thin-pool
metadata command 'lvextend -l+1 vg/pool_tmeta' does the change.

Patch gives better controls 'coverted' metadata LV and
reports less confusing message during conversion.

Patch set also moves the code for updating min/max into pool_manip.c
for better sharing with cache_pool code.

7b41ea61b2 config: move some config setting into commented part
It's better to set most of option as 'commented' with some
documented defaults instead of providing strict values.

This has the advantage we can eventually 'change' defualts
and get them working in future. Otherwise once the setting
is stored in lvm.conf in /etc, such setting has strictly
defined value and that can be only change with file update.

e82303fd6a lvcreate/lvconvert: optionally reenable mirrored mirror log for testing purposes only
This is a followup patch to commit edb72cb70c
to support related lvm2 test suite tests.

A 'global/support_mirrored_mirror_log' bool configuration variable gets
introduced allowing the creation of, or conversion to mirrored 'mirror'
logs if set.  The capability to create these in turn allows the rest of
the tests to perform activation of such existing LVs and their conversions
to disk/core 'mirror' logs.

Display a disclaimer warning if enabled that this is not for regular use.

Add definition of the enabled config option to respective test scripts.
