dmeventd: fix linking with libdevmapper

libdm library instead of its internal version

So external user of libdevmapper-event library has no other option
then to link with released libdevmapper library.

The complexity comes with lvm2 plugins.
The lvm2 plugin itself uses internal version of device_mapper,

any breakage on compatibility of internal i.e. dm_task_run structures.

the metadata area (page size offset from the start of the
device) and the first PE (1 MiB by default due to

area on machines with 4KiB page size (1024 KiB - 4 KiB),
and smaller on machines with larger page size.

If default_data_alignment was set to 0 (disabled), then
DEFAULT_PVMETADATASIZE 255 would take effect, and produce a
metadata area that was 188 KiB and pe_start of 192 KiB.
This was too small for common use.

This is fixed by making the default metadata area size a

Since _create_and_load_v4() reused already existing dm task from
DM_DEVICE_RELOAD it has also kept passing its table parameters
to DM_DEVICE_RESUME ioctl - but this ioctl is supposed to not take
any argument and thus there is no wiping of passed data - and
since kernel returns buffer and shortens dmi->data_size accordingly,
anything past returned data size remained uncleared in zfree()
function.

after use, but they may have been left in place.
