6ff65e6755 vdo: check_point_frequence is unused option
This vdo parameter existed in the early stage of integration of vdo into lvm2,
but later it's been removed from vdoformat tool - so actually if
there would be any non-zero value it would cause error on lvcreate.
Option was not stored on disk in lvm2 metadata.

Remove this vdo parameter from lvm2 sources.

(Although this vdo parameter will be still accepted on cmdline through
 --vdosettings option, but it will be ignored.)

829ab01708 device_mapper: add parser for vdo metadata
Add very simplistic parser of vdo metadata to be able to obtain
logical_blocks stored within vdo metadata - as lvm2 may
submit smaller value due to internal aligment rules.

To avoid creation of mismatching table line - use this number
instead the one provided by lvm2.

5e060b8fa7 vdo: support --vdosettings
Allow to use --vdosettings with lvcreate,lvconvert,lvchange.
Support settings currenly only configurable via lvm.conf.
With lvchange we require inactivate LV for changes to be applied.

Settings block_map_era_length has supported alias block_map_period.

3320ab8334 lib: move towards v2 version of VDO format
Drop very old original format of VDO target and focus on V2 version.
So some variables were renamed or replaced.
There is no compatibility preserved (with assumption so far this is
experimental feature and there is no real user).

Note - version currently VDO calls this version 6.2.

ccc35e2647 device-mapper: Fork libdm internally.
The device-mapper directory now holds a copy of libdm source.  At
the moment this code is identical to libdm.  Over time code will
migrate out to appropriate places (see doc/refactoring.txt).

The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).

All code using libdm should now use the version in device-mapper.
